Auto Zero and Oxygen Sensor Calibration

Auto Span

4. The LCD now prompts you to apply calibration gas

to the sensors.

Note

Do not apply calibration gas at this point, otherwise

auto zero may fail for that sensor and then it cannot

be spanned.

3. The LCD flashes

while the detector

automatically zeroes the toxic and combustible

sensors and calibrates the oxygen sensor. The

LCD notifies you if the auto zero has failed for a

sensor.

5. K flashes and remains displayed as you

attach the calibration cap and apply gas to the

sensors at a flow rate of 250 to 500 ml/min. (refer to

Figure 3. Applying Gas to the Sensors).

Auto Zero Sensor Fail

The audible alarm then beeps twice.
