Introduction
This section of the manual contains maintenance information for the HT-PR Dielectric
Withstand Tester. This maintenance information is divided into service information, general
maintenance, a performance test, and a calibration procedure. The performance test is
recommended as an acceptance test when the instrument is first received, and later as a
preventative maintenance tool to verify proper instrument operation. A 1-year calibration cycle
is recommended to maintain the specifications given in Section 1. A three inch piece of approx.
18 AWG insulated hookup wire with each end stripped back ½" and a lead with a banana plug on
one end are required to conduct the performance test. The test equipment required for the
calibration procedure is a DMM able to read true rms 0-2000Vac
± 1%, 0-2800Vdc ± 1%, 0.2 Ω
and 1.5
Ω
1/4 w 1% resistor.
