What to do if the display is blank on my Radiation Alert Inspector+ Measuring Instruments?
If your Radiation Alert Measuring Instrument shows a blank display, first, install a new 9-volt battery. If the count light and audio are working, the LCD may need to be replaced. This could be due to no battery, a dead battery, a poor battery connection, or a defective LCD.
Why does my Radiation Alert Inspector+ Measuring Instruments have a false high reading?
If your Radiation Alert Measuring Instrument gives a false high reading, it might be due to several reasons. First, try drying the instrument in a warm, dry place, as moisture can cause this issue; if the problem persists, it requires service. Also, remove the instrument from direct sunlight and ultraviolet sources. If the high count drops, the mica window coating may have washed off the Geiger tube due to getting wet, and the tube will need to be replaced. Replacing the Geiger tube is suggested if the issue is a continuous discharge. Lastly, move the instrument away from possible sources of electromagnetic or radio frequency radiation.
How to fix a Radiation Alert Inspector+ Measuring Instruments when the display works, but no counts are registered?
If the display of your Radiation Alert Measuring Instruments works but no counts are registered, the cause may be a defective Geiger tube or a bad cable. Look through the window to check the mica surface of the tube; if it is wrinkled or a break is visible, replace it and check the EXP cable connection.
