CALIBRATION
COMPLETE
Following a successful calibration, the system returns to the “Sample” mode and it will be necessary to reconnect the sample
gas line as follows:
Span Gas Calibration:
Assure there are no restrictions in vent line.
Regulate the pressure between 5-30 psig and set the flow rate to 2 SCFH for Fuel Cell sensors.
Air Calibration –
Standard Sensor and
Flow Housing:
The sample gas should still be flowing, if necessary open the FLOW valve.
With the left hand hold the gas connections of the housing and screw the oxygen sensor into the
flow housing with the right hand.
Air Calibration –
Optional Sensor and
Sensor Housing:
The sample gas should still be flowing, if necessary open the FLOW valve.
Reassemble the sensor housing.
Place the sensor face down in the bottom section of the sensor housing.
Ensure the o-ring is in place.
Install the upper section by gently pushing it straight down.
Ensure the PCB contacts the two gold pins.
Rotate the upper section of the sensor housing 90º to engage the clamp.
Using the 5/16 wrench supplied tighten the clamp bolt located in the center of the bracket attached
to bottom section with the elbow fittings to secure the sensor housing.
