7. Push the joystick down to display the “Set Sensor Zero” menu.
6.2.4 Setting Zero
IMPORTANT: This procedure should be performed under normal monitoring
conditions, without any of the target gas present. It is not recommended to use
zero air.
1.
Check the instrument’s gas concentration reading on the local display.
2.
If the display does not read a steady “0,” Use the following procedure to
adjust the zero.
3.
Push the joystick Right to enter the Zero adjust menu.
4.
Push the joystick IN, (like a doorbell) and the zero will automatically set to 0
ppm.
5.
Push the joystick UP to select the Sensor Span menu.
6.1.5 Span Calibration
CAUTION: Be sure to observe all safety guidelines when generating and using
calibration gases.
NOTE: The target gas concentration should be in the middle of the dynamic
range of the detector.
1)
Insert the sensor cell inside the Calibration cap (83505)
NOTE: DO NOT twist the sensor cell inside of the calibration cap as it will
cause the sensor electrolyte to leak. Gently rock the sensor side-to-side to
insert or remove the sensor cell to the calibration cap.
2)
Connect the Span gas regulator (CZF7R000255) to the Span gas cylinder.
3)
Connect the Sample tubing assembly to the span gas regulator and to the
calibration cap. Use the flexible tubing, (90054) to connect to the span gas
regulator. The calibration cap has a Push-to-connect connector. To insert the
tubing into the calibration cap, push the tubing firmly into the push-to-connect
on the calibration cap. (Please insure the proper flow direction on the cal cap)
