Technical Features

Test Voltage

0 to 5 kV

Rated Current

100mA Continuous

200mA Short term

Automatic & software controlled voltage setting to avoid abrupt voltage rise.

Automatic selection of seven different modes of operation for measurement of 3 terminal object from windows based software .

1) UST - Ungrounded Specimen test - 3 combinations

This mode is used when the object under test is not grounded.

This test provides most accurate results.

2) GST - Grounded Specimen test

This mode is used when the object under test is permanently grounded. This

test is used more often in outdoor installations, power systems etc.

3) GSTg - Grounded specimen test with guard. 3 combinations.

This mode is used for measuring them stray capacitances and separating

them from basic measurement in GST mode.
