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.

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).
