5. CONTINUITY (RESISTANCE) TESTS
WARNING
ENSURE THAT CIRCUITS TO BE TESTED ARE NOT LIVE.
DISCONNECT THE INSTRUMENT FROM THE CIRCUIT UNDER TEST
BEFORE OPERATING THE FUNCTION SWITCH.
TO SELECT THE LOW RESISTANCE RANGE SELECT "CONTINUITY"
5 ．1 Test Procedure
The object of continuity testing is to measure only the resistance of the parts of
the wiring system under test. Resistance value can be obtained by applying a
certain current to the resistor under test, and measuring the voltage generated
on the both sides of the resistor under test.
Resistance value(Ω) = Voltage(V) / Current(A)
This measurement should not include the resistance of any test leads used. The
resistance of the test leads needs to be subtracted from any continuity
measurement. KEW 6010B is provided with a continuity null feature which
allows automatic compensation for any test lead resistance.
Proceed as follows:-
1．Select the continuity test by rotating the function switch.
2．Connect the ends of the test leads firmly together (see Fig 2) and press and
lock down the test button. The value of the lead resistance will be displayed.
3．Operate the AUTO NULL SWITCH, this will null out the lead resistance
and the indicated reading should go to zero.
