When calibration is complete, you will see the screen change between these two:
CO:
Zeroed
CO:
0ppm
H2S: Zeroed
and
H2S: 0ppm
OXY: Zeroed
OXY: 20.9%
LEL: Zeroed
LEL: 0%LEL
When the zero calibration is successful, the display should show a reading of “20.9” for
the oxygen sensor and “0” for all other sensors.
6.5
Multiple Sensor Calibration
This function simultaneously determines the second point of the calibration curve for
multiple sensors in the monitor. The display counts down from 60 to 0 seconds, and then
shows the name of each sensor, whether it passed or failed calibration, and the calibrated
value for each sensor.
Select a sensor to calibrate by pressing [MODE] until the sensor’s name is highlighted.
Then press [Y/+] to toggle the selection on (indicated by an asterisk, *) or off (no
asterisk). To select other sensors to calibrate, press [MODE] until you reach the sensor
you want to select. Then press [Y/+].
After you have selected all the sensors you want calibrated, it is time to perform the
calibration.
1.
Attach the Calibration Adapter to the QRAE II (diffusion model only).
2.
Attach the regulator to the calibration gas cylinder.
3.
If your model is a QRAE II diffusion model, attach a hose to the Calibration
Adapter and to the regulator. If it is a QRAE II Pump model, attach a hose to the
regulator and to the inlet on the front of the QRAE II Pump.
4.
Turn on the regulator to start the Calibration Gas flow.
5.
Press [MODE] until OK is highlighted.
6.
Press [Y/+] to start calibration.
You should see a countdown from 60 seconds:
Calibration
in progress ... 60
Note:
If you see the following message, check that the gas is flowing and the hose is
attached:
No Gas Flow... Apply gas or hit any key to start.
