If your Troxler Measuring Instrument fails to display when powered on, first, plugging in the charger may turn on the instrument. Also, verify that the receptacle into which the charger is plugged has power. For older models, check the fuses located on top of each battery pack and replace them with Bussman type GMW 2 Ampere fuses if needed.
What to do if Troxler 3400-B counts moisture and density but is erratic?
If your Troxler Measuring Instruments counts moisture and density but is erratic and will not meet stability test, you may need to replace the Density or Moisture Module as required. Alternatively, consider replacing the High Voltage Module or the detectors/tubes as needed.
What to do if charger lamps come on but Troxler 3400-B still does not power on?
If the charger lamps on your Troxler Measuring Instrument come on, but the unit still does not indicate a powered on condition, consider replacing the Battery Monitor Module or the Front Panel Module.
Why is density count half the normal value on my Troxler 3400-B Measuring Instruments?
If your Troxler Measuring Instrument counts moisture correctly, but the density count is approximately half the normal value, check for a defective contact at the G-M tube. If the contact is fine, replace the defective G-M tube, or replace the Density Module.
What to do if Troxler 3400-B turns on but won't indicate counting condition?
If your Troxler Measuring Instrument turns on but will not indicate a counting condition when MEASURE is attempted, you may need to replace the High Voltage Module or the Front Panel Module.
How to repair Troxler 3400-B Measuring Instruments that counts density but not moisture?
If your Troxler Measuring Instrument counts density but not moisture, you should replace the Moisture Module, the Front Panel Module, or the He[3 ]tube.
What causes Troxler 3400-B to count moisture but not density?
If your Troxler Measuring Instrument counts moisture but not density, you may need to replace the Density Module, the Front Panel Module, or the G-M tubes.
