4.0 Calibration
CAUTION: In high velocity air ducts, air flow may need to be shut down before calibration takes place.
1. Verify that there is no air flow through the duct.
2. Remove the cal port plug.
3. Apply the target gas to the cal port at a flow rate of 500 milliliter per minute for combustible (FP
series) and solid state H2S (TP series) sensors. Apply a flow rate of 1000 ml/m for toxic gas (DM
series) sensors.
4. Follow calibration instructions provided in the sensor instruction manual.
5. Remove the target gas and apply a zero air standard for clearing.
6. If necessary, repeat items 3-5 as indicated in the sensor instruction manual.
7. Replace the cal port plug. Calibration is complete.

5.0 Maintenance
To remove the sensor for replacement or maintenance, perform the following steps:
1. Remove the two bolts that hold the sensor condulet to the duct mount plate.
2. Pull the sensor out of the duct mount chamber and perform necessary maintenance.
3. Reverse the procedure to replace the sensor. If necessary, lubricate the O-rings inside the duct mount
chamber so that the sensor rain shield will slide into the chamber easily.
