Step Four: Span Gas Calibration for the PID Sensor
4.1 The final step is to calibrate the PID sensor.
4.2 Connect the EntryRAE calibration adapter to the monitor (see Figure
6) and put a regulator (500 cc per minute flow rate) on the cylinder of
isobutylene.
4.3 Connect the open end of the calibration adapter to the regulator.
3.6 If calibration fails, the monitor briefly displays “Err”
above each failed sensor.
NOTE:
Stop calibration in the event that the
gas runs out or is disconnected. To interrupt
calibration, press @ . When calibration stops, the
sensors revert to their previous calibration values.
3.7 After briefly displaying the concentration, the
monitor moves on to calibrating the PID.
4.4 When “Span Cal?” appears on the display
with the VOC sensor indicated, press
Y
and turn the gas all the way on. The
monitor counts down from 30 seconds.
4.5 Turn off the gas, dicsconnect from the
adapter, and remove the calibration
adapter from the monitor.
If the calibration fails, the monitor briefly
displays “Err” above the failed sensor.
NOTE:
Stop calibration if the gas runs out
or is disconnected. To interrupt calibration,
press @. When calibration stops, the
sensors revert to their previous calibration
values.
