TROUBLESHOOTING

The following represent common troubleshooting tips for the PK II tester.

8.1

CORRECTING FOR POOR WEIGHT ROTATION

If weights do not rotate freely as described in Section 6.0, Step 4, perform the following:

Step 1

Check the cleanliness of the ceramic ball and nozzle.

Step 2

Make sure the tester is level by checking the bull

’

s eye.

Step 3

Isolate tester from environmental vibrations or relocate tester.

Step 4

Check for adequate air supply.

8.2

OUTPUT AND INTERNAL LEAKAGE

The accuracy of the tester is seriously undermined by leaks in the output connections and/
or instrument being calibrated. The following procedures are recommended to isolate and
correct for leakage.

8.2.1

Output Connection Leaks

Load the tester so as to apply a pressure to
the instrument being calibrated. Close (turn
OFF) the OUTLET valve. If the pressure indi-
cated by the instrument being calibrated re-
mains constant (holds at the indicated pres-
sure), it is safe to assume there are no leaks
in the output system (between the tester and
the instrument).
