AC or DC Current Measurements
CAUTION: Do not make current measurements on the 10A scale for
longer than 30 seconds followed by a 15 minute cool down period.
Exceeding 30 seconds may cause damage to the meter and/or the
test leads.
1. Insert the black test lead banana plug into the negative COM jack
and the red test lead banana plug into the;
a. Positive uA/mA jack for currents to 400mA
b. Positive 10A jack for currents to 10A
2. Turn the rotary switch to the uA, mA or A position.
3. Touch the test probes in series with the circuit under test and read
the current on the display.
Resistance Measurements
1. Insert the black test lead banana plug into the negative COM jack
and the red test lead banana plug into the positive Ω jack.
Turn the rotary switch to the Ω position.
2.
3. Touch the test probes to the circuit or device under test and read
the resistance on the display.
Capacitance Measurements
1. Insert the black test lead banana plug into the negative COM jack
and the red test lead banana plug into the positive CAP jack.
2. Turn the rotary switch to the CAP position.
3. Touch the test probes to the circuit or device under test and read
the capacitance on the display.
Frequency or Duty Cycle Measurements
1. Insert the black test lead banana plug into the negative COM jack
and the red test lead banana plug into the positive HZ jack.
2. Turn the rotary switch to the Hz/% position.
3. Press the Hz/% key to select "Hz" or "%".
4. Touch the test probes to the circuit or under test and read the
frequency or duty cycle on the display.
