4.2.3 Replacing O-ring in Fuel Arm
If calibration fluid is leaking at the fuel arm:
1. Pull cotter pin.
2. Tilt back clamp arm.
3. Lift out fuel connector and turn over. (Do not lose
spring and washer.)
4. Remove and replace O-ring.
5. Lower arm and reinstall the cotter pin.
4.2.4 Resetting Switches
Resetting the Motor Reset Button
In the event of a motor overload condition:
1. Remove the electrical box cover (lower left side
panel).
2. Press the main motor reset button.
3. Investigate why the motor was overloaded.
Resetting Flowmeter Limit Switches
If the flowmeter displays all zeros or will not display
flow readings, the limit switches may be tripped.
1. Disconnect power to the flowmeter by switching
the On/Off Switch (left side panel) to OFF.
2. Remove console rear cover.
3. Reposition the flowmeter piston so that the
adapter block is centered in the cavity.
4. Reconnect main power.
5. Restart the calibrator by switching ON the On/Off
Switch on the left side panel of the calibrator.
6. If the flowmeter again displays all zeros check the
optical detectors. They may have to be cleaned or
replaced.
7. Restart the calibrator.
8. If the flowmeter still will not work, the main
printed circuit board (PCB) may have to be
replaced, see Section 4.2.6.
