General Description

This precision instrument is an insulation meter tester and calibrator in one, specifically
designed to test and calibrate insulation test sets and megohm meters with varying ranges.
It consists of a high precision resistance box, a voltmeter and a milliamp meter.
It is constructed from very high insulation materials, including its case, and is fully isolated
from any external circuits including the mains supply.
All of the rotary selector switches are manufactured by Time Electronics, using special high
voltage low leakage wafers; the contacts are self-cleaning. This feature means they should
require no maintenance.
All parts of the instrument, including the bared leads provided (after custom 10 kV rated
probes are fitted) have been tested for safety up to ten kilovolts.
The three functions, Voltage Measure, Current Measure, and Source Resistance are
selected and used separately.
Maximum voltage is dependent upon humidity levels. Below 50% relative humidity is
recommended.
