How do i test a house electrical circuit


Well, sir, that will depend on our level of electrical knowledge.
Several options:
Try this, especially for a novice, is buy a ohm meter/electrical tester at a store and follow the instructions.
These cost in the neighborhood of 10 to 15 dollars at stores like car parts stores, Sears, or Wal-mart.
Another way is to buy an electrical tester that looks like a pencil, made of plastic, that you insert into an electrical outlet, or touch and electrical wire, and it will light up if you have electricity in the wire.
One more piece of information:
Where is or where are the "hot" ( dangerous) wires?
Answer:
If it is a wall outlet, the smallest of the two parallel straight slots in the outlet should be the "hot" (110volt) wire.
The other is the ground.
If you are testing a dryer outlet, the two side lugs are both 110 volt, and the bottom ( or top ) " L " shaped lug is the ground.
If you have a 4-slot socket, the side lug holes are hot, the top and the bottom ones are ground.
God bless your efforts.

After taken photos the image out of focus


On the front of the camera body, below the lens release button you should find a two position switch labeled "AF" & "M" This is the "Auto Focus - Manual" selector switch. Make sure the selector is set to "AF" for auto focusing.

Your lens may have a similar focus selector switch on its barrel. There are two types of switches used - depending on the lens. The first is labeled "M/A" and "M" The "M/A" position indicates it is in "Auto Focus" mode with a "Manual" focus over ride capability. You can simply twist the focus ring to change the focus to a point other than that chosen by the camera's auto focus system. The "M" position is Manual Focus mode. No focusing operations will be performed by the D80 auto focus system - focusing must be done by the photographer.

The second type has "A" & "M" positions. These represent Auto and Manual focus. The difference between this type switch and the "A/M & "M" switch is that when in "A", the camera will no allow the focus to be changed manually. There will be opposition to twisting the focus ring in the position. Forcing it will likely result in damage. The selector switch must be changed to "M" to change the focus.

If either switch is set to manual, the auto focus system will be disabled, so it is very important to have them both set to "A" or "A/M".

I hope this helps. Please rate my reply - thanks!

What a 2-range voltage tester used for


This simple, inexpensive tester is described by the manufacturer as a 2 range voltage tester. It appears to have two ranges of voltage that it can test for the presence 110-120 or 220-240 volts in a circuit. There is nothing to interpret, the device will indicate one or the other and whether AC or DC.

This could be useful for testing electrical circuits in homes in the US & Canada (and other places that use 120/240 utility system voltages). It will not help with finding split circuits, and will not be able to accurately display the actual voltage on a circuit. If there is a problem of a back fed circuit, passing 60 or so volts, the unit may indicate either no voltage, 110 volts or some other indication of voltage; but can not indicate how much voltage is present.

This device function more like a test light than anything else, and an inexpensive meter for $20 would provide much more information and have greater capabilities. Electricians do not use test lights or devices like this because not enough information is provided. I know you're not an electrician - but this tool is probably only good enough to let you know that some voltage above x number of volts and below 130 or more than 130 but less than 250 is present - that's about it.

I couldn't recommend the use of test light or testers like this to anyone. Just my two cents. Good luck!

I have 1994 town car the fuse keep blowing 15a number 1 as soon as i touch it the fuse blow can any one help me robertj125@hotmail.com


Probably your compressor for the air suspension. You can put a 12 volt light bulb in the circuit in place of the fuse while you diagnose the problem.

Here's the circuit.

2b94f90.gif Inspection and Verification
  1. Verify the vehicle owner's original concern by operating the vehicle to duplicate the condition.
  1. Inspect to determine if one of the following mechanical or electrical concerns apply:

    Mechanical Electrical
    • Shock absorber failure
    • Leak from air line(s)
    • Leak from air spring(s)
    • Ruptured air spring(s)
    • Height sensor damaged
    • Height sensor off ball studs
    · Open Fuses:
    • Town Car
      • Power Distribution Box Fuse U (30A MAXI)
      • Instrument Panel Fuse Panel Number 1 (15A)
    • Crown Victoria/Grand Marquis
      • Power Distribution Box Fuse AIR SUSPN PUMP (30A MAXI)
      • Instrument Panel Fuse Panel Number 1 (15A)
    • Loose Connectors
    • Corroded Connectors


You need a dealer tester for this check

AUTO TEST DIAGNOSTICS At the beginning of the automatic portion of the test, the control module checks for defective control module (DTC 70), for unstable battery voltage (DTC 80), then for shorted or open conditions that would create DTCs 39 through 46, and 68 through 71. If shorts or opens are detected, the automatic portion of the test is ended and a DTC 13 (Auto Test Failed) will be displayed on the SUPER STAR II tester. If no shorts or opens are detected, the automatic portion of the test continues. The control module attempts to raise and lower the vehicle to verify that all three air suspension height sensor states (trim, high, and low) can be reached. A properly functioning vehicle will be at trim height at the end of the Auto Test. If all three states are not reached, the Auto Test will end and again a DTC 13 will be displayed. A DTC 12 will be displayed at the end of the Auto Test only if everything checked to this point is functional. After the DTC 12 (or DTC 13) is displayed, the control module is ready to check for manual inputs. The manual inputs check the steering sensor and the door courtesy lamp switch circuits. During the manual test, the module continually monitors the door Circuit 159 or 24 and the steering sensor Circuits 633 and 634 Town Car, Circuits 834 and 835 Crown Victoria/Grand Marquis for activity. To pass the manual test the control module must detect that all four doors have been opened and closed, and that the steering wheel has been turned at least 1/4 turn in each direction. After the manual test, the STAR tester button must be toggled, or the control module will continue to monitor the manual test inputs indefinitely. Either a DTC 11 (Air Suspension OK) or other DTCs will be displayed at this time. After the Auto/Manual tests, the DTCs will be displayed automatically. Each DTC detected will be displayed for about 15 seconds. The code display will continue until all DTCs have been displayed. The display will repeat the DTC until the STAR test button is released (up). After all DTCs are written down, the pressed tester button may be released. DO NOT disconnect or turn OFF the tester. The tester is ready to enter the Functional Test.

I have an rs232 cable attached to kyrptview cable box via a usb adaptor.. Cant get my pc to see the box.. its a dell pentium 4 on windows xp.. any help pls


I assume the RS232 cable is going to a serial port? I think you should add a USB card to your system. The old async chips used to support RS232 ports are not fast enough to take USB info.

Printronix5003H+ table mismatch


I'm sure you have fixed your printer by now... but reflash the printer.

Flash memory is contained in SIMMs (single in-line memory modules) located
on the controller board. Printer emulation and operating system software are
loaded into flash memory at the factory, but you will install software in some
situations:
• The customer buys the PGL or VGL graphics, Expansion-CT, or IPDS
option after the printer is installed
• The customer needs to upgrade printer software
• The customer needs different emulation software
• You have replaced the controller board
• You have added or replaced the flash memory SIMM
Emulation and operating system software are stored as a compressed file on
a 3.5 inch floppy diskette. This file is “executable.” You will expand it and copy
it into printer flash memory.
You can load software through the serial, parallel, or Ethernet port of the
printer.
1. If the printer has an Ethernet interface, refer to the PrintNet User’s Manual
for the download instructions. You are finished with this procedure. If you
are going to load memory through the serial or parallel port, continue with
this procedure.
2. Make a printout of all saved configurations. (Refer to the User’s Manual.)
(Installing new software erases all saved configurations. You will use the
printouts to restore printer configuration.)
3. Set the printer power switch to O (off).
4. If the printer is already connected to the serial or parallel port of a
computer capable of running an MS-DOS® based PKZIP® self-extracting
file, go to step 11. If not, go to step 5.
5. Unplug the AC power cord from the printer.
6. Disconnect all data input cables from the printer interfaces.
7. Connect a parallel data cable to the LPT1 port or a serial data cable to the
COM1 port of an IBM-compatible computer that is using the PC-DOS™ or
MS-DOS operating system.
NOTE: You can connect the cable to the LPT2 port if the LPT1 port is alreadyin use. The load commands are different if you use this port, as
described in the note after step 18.
8. Connect the data cable to the appropriate I/O port of the printer.
9. Plug the AC power cord into the printer.
10. Power on the computer.
11. Insert the emulation or upgrade diskette into diskette drive A (or B) of the
computer.
12. Make the diskette drive the active drive by typing the following at the DOS
prompt:
A:<return> (If the diskette is in drive B, type B:<return>)
13. Get the name of the compressed file on the diskette by listing the
contents of the diskette; at the DOS prompt type:
DIR<return>
The compressed file on the diskette takes the form FILENAME.EXE
Now write down the complete name of the file with the .EXE extension.
14. On the printer control panel, press and hold down the ON LINE + PAPER
ADVANCE keys. Without releasing the keys, power the printer on.
Continue holding the ON LINE and PAPER ADVANCE keys down for five
seconds, then release them.
NOTE: The port default is CENTRONICS; this is the standard load through
the parallel port. If you want to use the default, continue at step 18.
15. When you see “WAITING FOR PROGRAM DOWNLOAD” on the LCD,
press the < (NEXT) key. “SELECT DOWNLOAD PORT =
DATAPRODUCT” appears on the LCD.
16. Press < (NEXT) again to cycle through the download ports available in
the printer:
DATAPRODUCT (parallel)
CENTRONICS* (parallel) (default port)
RS232-9600 (RS-232 serial, 9600 baud)
RS232-19.2K (RS-232 serial, 19200 baud)
RS232-38.4K (RS-232 serial, 38400 baud)
RS232-115K (RS-232 serial, 115000 baud)
RS422-9600 (RS-422 serial, 9600 baud)
RS422-19.2 (RS-422 serial, 19200 baud)
RS422-38.4K (RS-422 serial, 38400 baud)
RS422-115K (RS-422 serial, 115000 baud)
17. When the printer download port you want to use is displayed on the LCD,
press ENTER. “WAITING DOWNLOAD / PORT = <your selection>
appears on the display.
18. At the DOS prompt on the computer type:
FILENAME.EXE -pb<return>
where FILENAME.EXE is the compressed file you noted in step 13. This
command decompresses the file on the diskette and copies it as a binary
file into the flash memory on the printer controller board.
NOTE: If you are loading the file using the LPT2 port on the computer, enter
the following DOS command:
FILENAME.EXE -pb 2 <Return>
The 9600 baud rate is the only selection older versions of DOS can
use. The baud rate information entered in the following DOS
commands must match the selection you made in step 16.
the load process and status. (LCD messages are listed in Table 2,
page 37.)
CAUTION Do not interrupt the downloading process once it has started.
Interrupting a download will damage the flash memory on the controller
board and PrintNet card ( if installed).
19. When the new program has successfully loaded into memory and the
printer has reset itself, set the printer power switch to O (off).
20. Unplug the AC power cord from the printer.
21. Remove the diskette from the computer and store it with the printer.

Zebra Z4MPlus doesnt communicate with PC


Ok,

This machine has a parallel port. Try to print via parallel cable. If it works, consider staying with it. Serial ports are a pain to manage.
If you absolutely have to do it via rs232 though....
Question 1. Has it ever printed?
If yes, Go into Windows Printers and Faxes control and select the Zebra or whatever printer that you are using. Right click on it and you should get a menu that at the bottom say "Properties", select that, then you should get a new window with tabs at the top. You want the tab for "Ports". Select it and you will see all of the different output ports that you can direct your printing. RS232 is a COM port. So start at COM1, check it and try to print. If that doesn't work, go to COM2, etc.

Last resort, If you can't get control via the printer driver program, you will have to try redirecting the print manually (now you will understand why I said to stay with parallel output).
What you have to do is redirect your printing via the dos "mode" command.
Under "Start Menu" goto "Run" and put in "CMD" and click "OK".

This opens a black square window with a cursor blinking. Type in this:
mode com1:9600,n,8,1 (enter)

mode lpt2=com1 (enter)

Tell your program to use LPT2 if you can and see if it works.
By now a parallel cable instead of RS232 should be looking really good.
Good luck!

Black-box regd


There are NO drivers needed or even provided by BlackBox for this device. It simply uses hardware circuits to convert an RS232 signal to a RS 422/485 signal. My first reaction to this question is: Do you have your PC serial port at 9600baud which is the default RS232 signalling rate for this device? (I guess I probably won't hear a response on this as the question is almost a year old, with no attempts by anyone to solve it. I'm the only glutton for punishment.)
