4. 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”
4 ．1 Instrument layout See Fig 1.
4 ．2 Test Procedure
The object of continuity testing is to measure only the resistance of the parts of
the wiring system under test. 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. Model 6011A 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 dial.
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/Uc SWITCH, this will null out the lead resistance
and the indicated reading should go to zero.
4．Release the test button. Press the test button and ensure the display reads
zero before proceeding. While using the Continuity null function, "ohm"
symbol blinks. The null value will be stored even if the function switch is
