Calibration
Connecting the Gas Cylinder to the Detector
Refer to
, and the following procedures to connect
the gas cylinder to the detector for calibration. Read steps 1-6 before
starting calibration.
1. Verify the calibration gas being used matches the span
concentration value(s) that are set for the detector.
2. Attach a 0.5 l/min regulator to the gas cylinder. To calibrate with
the MicroDock II station, use a demand flow regulator and refer
to the
MicroDock II User Manual
.
3. Connect the calibration hose to the intake valve on the calibra-
tion cap and tighten the knob. Arrows on the calibration cap
indicate the direction of gas flow.
Do not attach the calibration cap until instructed to apply gas.
Note
Ensure the knob is securely fastened before applying gas. Do
not overtighten the calibration cap. Ensure strong air currents
are kept away from the exhaust side of the calibration cap, as
this can affect the calibration accuracy.
