Introduction
This section of the manual contains maintenance information for the HT-2800P
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 0-2800 Vdc
± 1% and a 3-ohm 1/4 w 1%
resistor.
