111 • Calibrating and Bump Testing the PPM Combustible Sensor 10,000 ppm Gas
• To return to the BUMP screen, press POWER ENTER.
• Disconnect the humidifier from the probe.
NOTE: Grasp the humidifier tube assembly by the clear tubing at the
end, not the humidifier tube itself.
If the ppm combustible sensor fails the bump test,
• The instrument will beep and a calibration is immediately and
automatically started. Continue to apply the calibration gas.
CAL on the bottom left of the screen will alternate with APPLY.
The calibration time will begin to countdown in seconds in the
lower right of the screen. The calibration time counted down
during a calibration initiated because of a failed bump test is
the difference between the bump test gas time and the
calibration time defined in the BUMP--SET menu item in
Maintenance Mode.
