Turn off the instrument.2. Remove the four screws holding the MultiRAE sensor compartment cover in place.3. Remove the cover to expose the sensors.4. Gently lift out the PID module with your fingers.5. If the module requires replacement (for example, because the lamp does not illuminate, or thesensor repeatedly fails calibrations), place a new module into the slot, being careful to match theindexing keys. The sensor can only go into its slot one way.6. If you want to open the sensor module to inspect and clean the lamp and sensor electrode panel,you must use the special tool (part number G02-0306-003, package of three). Its “C”-shaped endhas small “teeth” inside. Slide the tool so that the teeth slip into the notch between the module’scap and body:7. Gently pry up the cap using a rocking motion:8. Once the cap is removed, set it aside.PID Sensor slot
