Resistance Measurement
Measure circuit resistance up to 40MΩ.
WARNING!
To prevent electric
shock, disconnect all power to
circuit and discharge all high-voltage
capacitors before measuring.
Note:
When measuring ohms, start with
lowest range if resistance is unknown.
Note;
When measuring above 1MΩ, it may
take a few seconds for reading to stabilize.
1. Plug black Test Lead into
black
COM
Jack.
Plug red Test Lead into red Input Jack.
2. Turn Rotary Switch to
Ω
position.
3. Press
SELECT
button until
MΩ
is displayed.
Note:
For low resistance measurements,
short Test Leads together. If
there is resistance present, press
REL
button to zero out resistance
for most accurate reading.
4. Carefully touch exposed
conductors with tips of probes.
5. Read measurement.
Note:
If resistance value is too
high, display will read
OL.
6. When testing is complete, turn
Rotary Switch to
OFF
, remove
Test Leads and store with Meter.
Frequency/Duty Cycle Measurement
Measure frequency up to 1MHz.
1. Plug black Test Lead into
black
COM
Jack.
Plug red Test Lead into red Input Jack.
2. Turn Rotary Switch to
Hz%
position.
3. Connect Test Leads across
circuit to be measured.
4. Read measurement.
5. Press
Hz%
button to
switch to Duty Cycle.
6. Read measurement.
7. When testing is complete, turn
Rotary Switch to
OFF
, remove
Test Leads and store with Meter.
