Triple range: 0-5kV, 5-15kV and 15-45kV
with optional accessory R-45 add-on resistor sticks.
• This meter does not measure voltage.
• Determine phase rotation on systems up to 5kV
with the selector switch set for LO range and
without the add-on resistor sticks.
• Determine phase rotation on systems up to 15kV with the
selector switch set for
HI range and without the add-on resistor sticks.
• Determine phase rotation on systems up to 45kV with the
selector switch
set for HI range and with the optional add-on resistor
sticks installed,
one on each meter stick.
The PT-5000B Proof Tester will produce 5kVDC at the test leads to confirm proper operation of the phase rotation meter. The PT-5000B operates from one 9V alkaline battery and produces approximately 5kVDC at the connecting leads. To use: 1) Connect both tester leads to the phase rotation meter probes. Isolate the ground lead from ground or any other conductor and do not touch it during the test. 2) Press and hold both TEST buttons. 3) Confirm a good battery by checking the red light on the Tester.
If the red light does not come on, replace the battery with a 9V alkaline only. 4) Verify the phase rotation meter reads approximately 5kV. 5) Release the TEST buttons and disconnect the Tester from the phase rotation meter. WARNING: Do not use the phase rotation meter if proper operation is not confirmed. WARNING: Do not use this tester except as directed. Do not use to test equipment other than the phase rotation meter. Do not apply to energized circuits or equipment. Refer all servicing to the factory. Failure to follow these instructions may lead to electric shock, severe injury or death.
