    sorry i have used this about 12 months ago but because i have lost the instructions iam a bit lost

    If you do not have a basic understanding of the meter, I would advise you to be very careful with it's use. Too easy to get hurt without proper training, people tend to forget that electricity can kill when they cannot see it. I'd prefer to not try to instruct you on the use online.

I understand your question.

My concern is trying to explain operation of a meter that will or can be used on live electrical could result in someone getting hurt.

Here's a few simple directions (assume this is a digital meter, if it is an analog (needle pointer) meter, then my instructions might be a bit different.

General rule: Most meters have multiple voltage selections. Always start at the highest voltage selection and if the reading is too small to accurately read, slowly choose lower settings until you reach a voltage selection that gives a proper reading.

General Safety: Never touch anything metal while working with electricity. Remove all jewelry (watches, rings, (yes, even that wedding band, your spouse would rather see you alive with all of your fingers), necklaces, piercings, etc.)

Wear rubber shoes, do not stand in water, if you are sweaty, dry off and cool off.

Old electrician trick of the trade to prevent shock is to always work with one hand behind your back or in your pocket. This prevents you from becoming part of the circuit. However, hard to take electrical measurements with one hand. Improvise.

Voltage: Use this to measure the voltage output of a circuit, includine outlets, batteries, etc.

AC Voltage (alternating currents)- This is the type of voltage you have at your wall outlets. Should place the meter at the highest setting, usually is 1500 or 600 volts. Place the metal tips of the probes on the individual contacts. Take care to never cause the probes, while in contact with the live circuit, to touch each other. If unsure if the circuit is AC or DC, start here. Then you can switch to DC. (Note: Most DC

DC Voltage (Direct Currents) : This is the voltage from batteries. Most battery voltages are 24 volts or lower. However, if you are working on a special circuit, perhaps a solar electrical panel or some other type of circuit for storing electrical power for a residential backup power source, or perhaps a Uninteruptible Power Supply (UPS) for a computer, you may see higher voltages.

Note: Even if you think you know the voltage, start at the highest setting: On analog meters, you must choose polarity (+ and -, red and black) correctly, or you could destroy the readout. However, if you were on the highest setting, the meter movement would likely try to go in the wrong direction, but the amplitude of the movement would be small enough to protect the meter.

Resistance, Ohms or Continuity (often marked by the Greek letter OMEGA, which stands for Ohms. Sorry, not sure hot to get the OMEGA letter on here) - CAUTION: Only use these settings when the taking measurements on a circuit that is not live, is not plugged in or powered by batteries. If unsure, use the voltage settings to test first, if any voltage present, cannot check the continuity. (And if you have voltage, likely there is some continuiity.) A discussion of how to use these measurements is beyond the scope of this discussion.

AMP readings: Danger, danger: Some meters have the ability to read amps. However, unless using a clamp on meter type to read, this is the most dangerous for the person and the meter. (I've blown up two meters this way. )
Basically, the meter becomes part of the circuit, and all of the electricity to power what you are testing must run through the meter. If the item being tested draws 12 amps, and you have a 10 amp meter (usually the highest amp setting on most non-commercial meters) smoke will be released by the meter and you can kiss it goodby. (Hopefull, you are still in a mode where you can pucker your lips and your hair is not also emitting the pungent odor of burnt hair.)

With a clamp on meter, this is not a problem, usually, as the meter never becomes part of the circuit.

Hopefully, this gives you a basic understanding without putting you at risk for getting hurt or killed. (Note, I have a degree in engineering, was trained by my dad from a young age to respect electricity and use meters, and I have blown up two meters though no major fires. )So, please be very careful when using a meter. Please.

I take no responsibility for any damage you do to yourself, your meter, or your home, car, etc.

I have a mini cooper 2003 and none of my brake lights work.i thought it might be brake light switch but when i put a wire across the connector lights still wont come on. fuse ok


Have you checked for power with a multimeter at the switch ? I'm going to say the obvious....you didn't say if you checked the bulbs ?
All being well there...find the grounding spur and check that is sound and that all wiring plugs are secure and not fouled up.

How do i use a multimeter


Black lead connector is the Neg. or the common, seems, goes in the bottom most socket on your meter and the red one on the very top one. Not the one marked for Amps. Then test the meter for working, turn the dial on the multimeter to resistance X1 or X100, with the meter on, touch the probes together to see meter deflection.
Make sure you put the meter on to volts after this to test voltage AC or DC.

Dse q-1559 Digital Multimeter


hi ,my q1559 is doing exactly the same ,are you using a rechargeable battery that is pretty old ? My point is I put a new battery in and it disappeared . I don't know if this is your problem but try cleaning the test meter probes connector, because the audible warning is telling you have a test lead connected to amps post whilst the switch is not turned onto measure amps..I used a cottonbud it fits perfect soaked in contact cleaner.

How to test the mulltitester in a speaker


Hello
There are mainly two type of multimeters. The first type is analogue one, which will have a needle deflects inside its dial to show measurements, and the second one is digital, which will look like a handheld calculator, in which measurements are displayed digitally. You can read it diretly from it.I don't know which type of multimeter is you are using. If it is digital one, set it to Ohms range, and connect the tow meter probs to the two terminlas of the speaker. Before doing this, check the impedence, marked on the speaker magnet. Usually it will be marked between 4 & 8Ohms. You must get this marked Ohms measured on meter scale. For bothe type of multimeter, the proceedigns are the same.Please don't hesitate to rate this solution. OK.

Dear Sir:

Thank you by your request, I will help you inmediately.

How to measure FUSEAND CONTINUITY A digitalmultimeter is the ideal multimeter t use to check fuses. You can test afuse using either a digital volt-ohmmeter or an analog volt-ohmmeter. Thedigital multimeter uses a LCD to indicate the condition of the fuse under testwhile an analog meter uses a traditional meter movement to indicate the fusecondition. Difficulty: EasyInstructions
Things You'll Need
  • Digital multimeter or analog multimeter
1. Usinga digital multimeter
o 1 Connectthe test leads to the volt-ohmmeter. Plug the black test leads into the blackjack marked "Com" or "Common" on the front of the meter.Plug the red test lead into the red jack marked "Volts/Ohms" on thefront of the meter. o 2 Setthe meter's function switch to "Ohms" and the range switch to the"R x 1" scale. If your digital multimeter is an auto ranging meter,you will not have a range switch. Instead, you'll have just a function switchbecause the meter will automatically select the right range for the quantitythat you are measuring. o 3 Turnoff the power and remove the fuse to be tested from the circuit. Never test afuse for continuity while it is still connected to the circuit that it is usedto protect. If the circuit still has voltage, the meter will be irreparablydamaged. If the fuse is still in the circuit when tested it is possible to geta false indication that the fuse is good if the meter gets a completed circuitthrough other circuit components. To be safe, always remove the fuse from thecircuit before testing it. o 4 Touchthe black test probe to one end of the fuse and the red test probe to the otherend of the fuse. It does not matter which probe you touch to which end becausefuses are not polarized. You are checking to see if there is continuity throughthe fuse element. A reading of approximately 0.5 on a digital meter's LCDindicates a good fuse. Most digital meters read their own internal fusesresistance, hence 0.5 Ohms and not 0.00 Ohms. LCD readout of "O.L."indicates no continuity through the fuse. The fuse is bad and needs to bereplaced.

Thank you in advance sincerely. God bless you.

Water may stay hot for 5 minutes then gets cold. water heater often blows breaker or pop out switch.


I suggest taking 30 minutes and testing water heater parts.
Right away we know 2 things:
-Electricity to heater is good.
-Upper element is receiving power because you have some hot water. If upper element was burned out, you would have no hot water.

That leaves 5 suspects:
Upper thermostat.
Lower thermostat.
Loose or shorted wire.
Upper element shorted to ground near center of element.
Lower element shorted or damaged in some manner.

Buy $10 milti-meter from Home Center or hardware
When test calls for testing voltage, rotate multimeter dial to 240-250-277 VAC.
When test calls for testing elements or continuity, rotate multimeter dial to Ohms.
Take 30 minutes and go down page.
Test will identify problem(s) and show how to fix it yourself.

How do I set digital multimeter to measure resistance


plug black lead into bottom socket. Red lead goes into middle socket.
Select the Ohms range on the dial... the lower left section ... Denoted by a Greek letter Omega (Upside down horseshoe)
set the range on the dial (This meter goes from 200 to 2000K ohms)
and read away....

I have two questions. The first is what is the


The dial is for selecting which of the "multi" things you need for measuring (metering).

Set the dial to the DC area and select 20V or whatever is the lowset DC voltage setting that is higher than the battery voltage.

The meter does not put a "load" on the batteries, so the test is just an estimate of freshness of the battery.

Notes:
The meter voltage does not present any danger to the user. If you are not experienced, do not check any AC voltages.
