7.3. Measuring Resistance
WARNING!
Never connect the test leads to a source of voltage when you have the
selected the OHMS function and plugged the test leads into the V//Hz-
terminal.
Be sure that the circuit under test has all power removed and that any
associated capacitors are fully discharged before you make a resistance
measurement.
The resistance measuring circuit compares the voltage gained through a
known resistance (internal) with the voltage developed across the
unknown resistance. So, when you check in-circuit resistance, be sure
the circuit under test has all power removed (all capacitors are fully
discharged).
1. Set the rotary selector to the position.
2. Plug the black test lead into your meter’s COM terminal and the red
test lead into your meter’s V//Hz-terminal.
3. Connect the test leads to the device you want to measure.
Notes:
If the measured resistance value exceeds the maximum value
of the range selected, "OL" appears. This indicates an
overload. Select a higher range. In this mode, the beeper
does not sound.
When you short the test leads in the 600 range, your meter
displays a small value (no more than 0.3 ). This value is
due to your meter´s and test leads internal resistance. Make
a note of this value and subtract it from small resistance
measurements for better accuracy.
