The PST-2000 cannot test voltmeter gauges. See AMETEK Dixson
Product Information Note 072-40287 for information about trouble-
shooting voltmeter gauges.
Important!
The PST-2000 cannot calibrate gauges. Do not set the tool to a par-
ticular frequency or resistance value and then check the pointer
position. Instead, use the tool to position the pointer as directed in
the procedure, note the value indicated on the tool and verify it
falls within the given frequency range listed in the Accuracy Table
referenced by that procedure.
When using the tool to position the pointer to full scale, the fre-
quency displayed on the tool corresponds to the values given in
the Accuracy Tables called out in these procedures and not with
other calibration charts and booklets.
