Dc Milliamp Measurement; Ac Voltage Measurement; Resistance/Continuity Measurement - Kopp GMT-12A Manuel D'utilisation

DC Milliamp Measurement

1) Fully seat the test leads in the correct input jacks.
2) Set the function/range switch to the 250 DCmA setting.
3) Put the test leads in series with the circuit (in line with
the circuit) so that the circuit current passes through the
multimeter in order to make the measurement. If the need-
le indicator defl ects to the left, reverse the test leads. Read
the measurement on the 0-250 scale.

AC Voltage Measurement

1) Fully seat the test leads in the correct input jacks.
2) Set the function/range switch to the appropriate AC voltage
range. If the voltage is unknown, use the highest range. If
the voltage applied falls within the range of a lower setting,
reset the function/range switch to the appropriate setting
for greater accuracy.
3) Touch the test leads to the circuit under test. With AC volta-
ge, the polarity of the test leads is not a factor.

Resistance/Continuity Measurement

For resistance and continuity testing POWER MUST BE OFF:
1) Fully seat the test leads in the input jacks.
2) Set the function/range switch to the Rx1K position (resis
tance indicated multiplied by 1000) and short the test
leads together. Using the zero ohms adjustment 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 battery with a new 1.5 volt AA
size battery (see Battery Replacement).
