Three terminal connection
Three terminal measurement permits the connection of all three test leads for A, B and E (or tip, ring and ground). The measurement pair is selected from the A-B-E (T-R-G) button on the front panel. Selection is confirmed in the display. No disconnection of test leads to measure individual pairs are required.
Alternatively the units can be used as a conventional two terminal instrument.
Insulation resistance testing
The feedback controlled insulation test voltage is now accurate to +2% -0% compared to the original +20%, providing a more accurate test voltage without the risk of over-voltage damage to circuits.
A variable range allows the exact test voltage to be selected from 10 V up to 500 V.
