Why won’t it stay on / why won’t it charge?.The main disadvantage of infrared sensors is their sensitivity to mechanical disturbances. The main advantages of the Fieldpiece IR sensor are that its sensitivity will remain the same over the life of the instrument, the sensor will last the lifetime of the instrument, it will not trigger on humidity or on oil, and it has nearly the same sensitivity to most refrigerants. It detects a CHANGE in concentration, so the wand must keep moving. The DR82 uses an infrared (IR) sensor.Its major disadvantages are that the sensor becomes less sensitive over life, eventually needing replacement and it is more sensitive to some refrigerants than others. The heated diode’s advantage is that it detects absolute concentration levels so it can be held on a leak and will continue to beep. What is the difference between the DR58 and DR82?.If this does not fix the issue try replacing the sensor If it seems like your leak detector is no longer picking up leaks or is not as sensitive as it was when you first bought it, try replacing the filter. The sensor can be inserted in two different configurations, either of which will allow the DR58 to function correctly.

Carefully insert the new sensor and replace snoot.Contact your local Fieldpiece supplier and have them order part number “RHD1”.Then, unscrew the snoot on the DR58 and if replacing gently pull the sensor from the base. To install or replace the sensor, make sure the unit is turned off.
