23.3 Maintenance And Calibration
The sensor module should be calibrated if it does not pass a bump
test, but no less than every 6 months, depending on use and exposure
to gas and contamination.
23.4 Replacing the Lamp And Filter
The sensor module is shipped with the lamp, sensor, and stainless-
filter installed. Periodically check the filter for dirt and contamination,
which can impact the reading and response time.
Note: Always turn off power to the DigiPID before checking and
servicing any parts. After inspection and/or replacement of parts,
recalibrate the instrument.
The lamp and sensor are not interchangeable with parts from other
manufacturers; use only RAE Systems replacements. Use of non-
RAE Systems components will void the warranty and can
compromise the safe performance of this product.
