NOTE: If one of the control buttons is not pressed within 10 minutes, the
unit will return to Measuring Mode automatically.
6. Attach the regulator to the gas cylinder. The fixed-flow regulator
automatically begins introducing the calibration sample to the sensor.
7. Let the gas flow for two minutes. After two minutes, press the POWER/
MODE button. The unit will adjust the span (CO-01 and HS-01) or zero
(OX-01) based on the calibration value that was saved in step 5 above.
As soon as the unit makes the calibration adjustment, it will begin its
start-up sequence, and then it will enter Measuring Mode.
NOTE: If the 01 Series displays “FAIL” on the LCD after you press the
Power/MODE button, the sensor output may be too low or too
high or there may be a problem with the calibration gas or
calibration kit setup. Refer to the Troubleshooting section in
Maintenance to solve the problem.
8. Remove the regulator from the gas cylinder and the calibration adapter
from the unit.
NOTE: If the gas reading is high enough (low enough for the OX-01)
when the unit enters Measuring Mode, an alarm condition will
occur. If this occurs, reset the alarm using the POWER/MODE
button when the gas reading falls below (rises above for the OX-
01) the alarm point.
