Cleaning the 10.0 eV or 10.6 eV PID Lamp
WARNING: When the battery indicator is blank, approximately 2 weeks of battery life remain.
CAUTION:
The internal components can be static sensitive. Use caution when opening the
enclosure and handling internal components. DO NOT use any metal objects or
tools to remove the sensor.
Clean the 10.0 eV or 10.6 eV lamp if you notice a significant drop in sensitivity from one
scheduled calibration to another or if you are not able to calibrate the detector.
11.7 eV lamps should not be cleaned because of their susceptibility to moisture.
