Resistance Measurements

Measure circuit resistance up to 20M Ohms.
WARNING! Do not measure resistance
on circuit with voltage running through it.
Notice: When measuring Ohms,
start with the lowest range if the
resistance is unknown.
1. Turn the Range Selector Switch
to the 200Ω position.
2. Plug the red Test Lead into the V/Ω/
Hz Jack. Plug the black Test Lead into
the COM Jack. Switch the Multimeter
ON. Short the Test Leads together.
The meter should read "0" Ohms.
3. Touch the exposed conductors
with the tips of the Test Leads.

capacitance Measurements

Measure capacitance up to 20μF.
1. Turn the Range Selector Switch to the
20μF position. Start with the highest
range if the capacitance is unknown.
WARNING! Fully discharge
capacitor before measuring.

Frequency Measurements

Measure frequency up to 20kHz.
1. Turn the Range Selector Switch
to the 20kHz position.
2. Plug the red Test Lead into the V/Ω/Hz
Jack. Plug the black Test Lead into the
COM Jack. Switch the Multimeter ON.

4. Read measurement. If the reading is
"1", set the Range Selector Switch to
the next higher Ohm (Ω) position.
5. When measuring resistance above 1
MΩ, the meter may take a few seconds
to give a stable reading. This is normal
for high resistance measurements.
6. At the 20MΩ range, the display reading
will be around 0.1 counts over the
actual measurement. These counts
should be subtracted from the resulting
reading. For example, when measuring
10 MΩ resistance, the display will read
10.1, but the correct measurement
should be 10.1-0.1=10.0MΩ
7. Remove and store Test Leads.
2. Plug capacitor into the
capacitance testing socket (Cx).
Switch the Multimeter ON.
3. Read measurement. If the reading
is less than 20μF, set the Range
Selector Switch to a lower range.
WARNING! Avoid electric shock.
Remove capacitor before switching
between testing modes.
Note: Reading is possible at input
voltages above 10Vrms, but the
accuracy is not guaranteed.
Note: In noisy enviroments, use a shield
cable to measure smaller signals.
3. Remove and store Test Leads.
