Resistance/Continuity Measurement - Kopp GMT-19A Mode D'emploi

Resistance/Continuity Measurement

For resistance and circuit continuity testing with power OFF
1) Fully seat the test leads in the input jacks.
2) Set the function/range switch to the Rx1K position and
short the test leads together. Using the zero ohms adjust-
ment dial, slowly turn the dial until the needle indicator
reads -0- ohms at the right end of the ohms scale. If the
needle will not zero, replace the internal batteries with two
new 1.5 volt AA size batteries (see Battery Replacement) .
3) Touch the test leads to the resistance or non-energized
circuit to be measured. Measure the value of the reading
on the ohms scale and multiply the reading by 1000. If
you're making basic continuity tests, the needle indicator
should move all the way to the right side of the ohms scale
if continuity exists.
Note:
When switching the unit back and forth from ohms to other
functions, always zero the needle indicator before taking
another reading. Failure to zero the needle before taking
resistance/continuity measurements will result in inaccurate
readings.

Continuity Buzzer Setting
For quick, audible continuity checks, turn the function/range
switch to the setting. If the circuit under test has a resis-
tance of 100 ohms or less, the internal buzzer will sound when
the test leads are touched to the circuit. This makes continuity
checks quick and easy.
Note: The needle indicator will not indicate resistance values
when the tester is in the mode. Do not operate the continu-
ity buzzer continuously as this will discharge the internal
batteries.
