The KT62 Multi-Function tester performs six functions in one instrument.
1 Continuity tester
2 Insulation resistance tester
3 Loop impedance tester
4 Prospective short circuit current tester
5 RCD tester
6 Mains voltage warning when operating the loop impedance and
RCD mode.
The tester is designed to Safety Standard IEC 1010-1/BS EN 61010-1
CAT III(300V).
The instrument is supplied with:
1A distribution board or lighting circuit test lead for
LOOP/PSC/RCD testing.
2 A lead for LOOP/RCD testing at socket outlets.
3 A lead for insulation and continuity testing.
4 External Earth Probe for loop testing.
In the insulation resistance testing mode the instrument provides a rated
current of1mA as required in BS 7671 (IEE Wiring Regulations) and BS EN
61557-2 1997.
In the continuity testing mode the instrument provides a short circuit
current of 200mA as required in BS 7671 (IEE Wiring Regulations) and BS
EN 61557-4 1997.
Continuity and insulation resistance functions have the following features:
Live circuit warning A colour coded LED warns if the circuit
under test is live.
Continuity Null Allows automatic subtraction of test
lead resistance from continuity
measurements.
Polarity switch Allows switching of polarity during
continuity tests.
Auto discharge Electric charges stored in capacitive circuits
are discharged automatically after testing
by releasing the test button.
