Question about HP 48gx Calculator

1 Answer

HP 48gx I use the 48 as a data collector for land surveying. When I take the shots it records the data correct in the sideshot, traverse screen. But when I inverse from point to point in the inverse menu, it gives me a terribly wrong azimuth and distance. Is there anything I can do to fix this problem?

If you are using the TDS software it may be in the backsight menu - try changing your angle to angle right- if not already set up that way - should work

Do you have anything on the stack? The DUP function duplicates the top element of the stack. If the stack is empty then you'll get this error because the calculator can't duplicate nothing.

I just had this exact problem so I reset the memory as instructed below. Know I am back in business. Memory reset A memory reset will return the HP 48 to its factory-default state, which will erase all stored user memory. Use this feature very carefully.
  1. If necessary, turn the calculator on.
  2. Press and hold the ON+A+F keys simultaneously.
  3. Release all three keys at the same time. This should cause the calculator to display the message "Try to recover memory?"
  4. Press the A key to attempt to recover memory or the F key to erase the user memory. When A is pressed, occasionally the objects in memory are recovered in new sub-directories of HOME labeled D.01, D.02, et cetera, although there is no guarantee that all of the variables will be recovered. Pressing the F key will cause all information stored by the user to be erased from calculator memory. This will also affect any RAM card that is merged with main memory. If the card is not merged or it is write-protected, it will not be affected by this reset.
Hardware symptoms and solutions I. The display screen has a blue/purple blotch of color, even when the unit is off The screen is damaged, and the calculator requires service. Please contact HP . II. All of the pixels on the screen are lit (blue)
  1. Try to adjust the contrast by holding down the ON key and repeatedly pressing the [ - ] key.
  2. If the screen is still dark, try to halt the system using the keyboard.
  3. If this does not correct the problem, try to reset the system using the reset hole with the batteries removed.
  4. If this does not work, remove the batteries and let the unit sit for 48 hours. After 48 hours, replace the batteries. If the problem persists, attempt a memory reset. Although removing the batteries for 48 hours should erase the user memory, performing a memory reset will ensure that the calculator is reset to its factory defaults.
  5. If the problem persists, the unit requires service. Please contact HP .

Here is the link to a web site where you can find resources for the HP48GX ( apparently your calculator is an HP 48SX).

On this other site you can view surveying software for the HP 48GX that is still available for sale.

My HP 48GX with COGO Card is running slow.


Hello,
You should perform the dagnostic tests.

The following procedure valid for the 48G should work for the HP48GX.
Make the calculator perform a
Self test.
  1. Turn calculator on
  2. Press and HOLD the key [ON]
  3. Press and release the key with "E" to its right (the one before last in first row)
  4. Relaese the [ON] key.
It tests the RAM and ROM. You will see various patterns on screen. Afterwards you should see
IROM OK,
IRAM OK,
HP48GX OK
The self test will continue repeatedly until you perform a
System Halt
  1. Press and HOLD the [ON] key
  2. Press and release the "C" key
  3. Release the [ON] key.
The empty stack should appear.

If you do not see IROM OK and IRAM OK, the calculator requires service.

If the above procedure is successful, you may want
to test the keyboard.
  1. Turn calculator on
  2. Press and HOLD the [ON] key
  3. Press and release the "D" key.
  4. Release the [ON] key
  5. Press and release the "E" key. KBD 1 should appear on the top left corner of the screen.
  6. Starting at the upper left corner of the keyboard, and moving Left to right, press every key in sequence. If you follow the sequence and the keys are functioning properly you should hear a hight pitch sound at each press.
  7. If everything is OK, when you press the last key (+) the screen displays KBD 1 OK.
To exit the keyboard test proceed as described above under System Halt.

If you follow the proper sequence and a hexadecimal number appears after pressing a key, the calculator requires service.
Hope it helps.
