DC Current Measurements

WARNING:
Observe all safety precautions when working on live circuits.
Do not measure current on circuits that exceed 250V. Measurements in the 10A
range should be limited to 30 seconds maximum every 15 minutes.
1. Insert the black test lead into the
negative COM input jack.
2. For current measurements up to 10A
DC, set the rotary function switch to
the 10A range and insert the red test
lead into the 10A input jack.
3. For current measurements up to
200mA DC, set the rotary function
switch to 200mA and insert the red
test lead into the positive mA input jack.
4. Remove power from the circuit under
test, then open up the circuit at the
point where you wish to measure
current.
5. Touch the black test probe tip to the
negative side of the circuit. Touch the
red test probe tip to the positive side
of the circuit.
6. Apply power to the circuit.
7. Read the current in the display. For
mA DC measurements, reset the rotary
function switch to successively lower
positions (20mA and then 2000µA) to
obtain a higher resolution reading. The
display will indicate the proper decimal
point and value. If the polarity is
reversed, the display will show (-)
minus before the value.

Operation

Resistance Measurements

WARNING:
Never test resistance on a live circuit.
1. Set the rotary function switch to the
highest
position.
2. Insert the black test lead into the
negative COM input jack. Insert the
red test lead into the positive
input jack.
3. Touch the test probe tips across the
circuit or component under test. It is
best to disconnect one side of the
device under test so the rest of the
circuit will not interfere with the
resistance reading.
4. Read the resistance on the LCD display
and reset the rotary function switch as
needed to obtain higher resolution. The
LCD display will indicate the proper
decimal point and value.
