6.3. 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/
/CAP/Hz/Temp.-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 desired OHM range.
2.
Plug the black test lead into your meter’s COM terminal
and
the
r
ed
test
lead
into
your
meter’s
V/
/COM/Hz/Temp.-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 flashes. This
indicates an overload. Select a higher range. In this
mode the beeper does not sound.
* When you short the test leads in the 200
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.
