Considerations for Different Types of Sensors.
Step 2
In the Sensor Configuration Menu (passcode 3032), press either ARROW key
to scroll through the menu and select the channel with the Oxygen sensor you
want to calibrate. Press ENTER and use the ARROW key to scroll to Calibrate
Zero. Press ENTER and use the ARROW keys to enter a value of 0.
Attach the regulator to the cylinder of Nitrogen (N
2
), insert calibration adapter
into the sensor opening on the front of the enclosure door (see Section 7.3.1
Calibration Adapter Plug if the adapter will not fit). The Zero Calibration will
start when the flow of gas is detected.
When the process has finished and the Zero calibration was accepted, press
ENTER to Exit and remove the cylinder of Nitrogen gas. Refer to Section 7.3.3
Zero - Requires Override if the Zero calibration was not successful.
8 ACCESSORIES
8.1 Splash Guard (Option -S)
The splash guard attaches to the front of the
enclosure to protect the sensor during water spray
or washdown applications. It is factory installed and
when attached the enclosure meets IP54 standards.
To calibrate a device with a splash guard, use the Cal Clip.
NOTE:
A specialize splash guard (Option -SN) must be used for sticky gas
sensors such as Chlorine (Cl
2
), Chlorine Dioxide (ClO
2
), Hydrogen Chloride
(HCL), Hydrogen Cyanide (HCN), Hydrogen Fluoride (HF), Ozone (O
3
) and
Phosphine (PH
3
).
NOTE:
A splash guard will slow down the response time of the sensor.
