5-3. MV Voltage Measurements
5-4. DC Current Measurements
CAUTION:
Do not measure mV voltages if a motor on the circuit is being switched ON
or OFF. Large voltage surges may occur that can damage the meter.
CAUTION:
Do not make 20 A current measurements for longer than 30 seconds.
Exceeding 30 seconds may cause damage to the meter and/or the test leads.
1. Set the function switch to the mV position.
2. Press the
MODE
button to indicate “
DC
”or “
AC
”.
3. Insert the black test lead banana plug into the negative
COM
jack.
Insert the red test lead banana plug into the positive
V
jack.
4.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.
5.Read the mV voltage in the display.
1. Insert the black test lead banana plug into the negative
COM
jack.
2. For current measurements up to 6000 μA DC, set the
function switch to the μA position and insert the red test
lead banana plug into the μA/mA jack.
3. For current measurements up to 600 mA DC, set the
function switch to the mA position and insert the red test
lead banana plug into the μA/mA jack.
4. For current measurements up to 20 A DC, set the
function switch to the 10A/HZ/% position and insert the
red test lead banana plug into the 10 A jack.
5. Press the MODE button to indicate “DC” on the display.
6. Remove power from the circuit under test, then open
up the circuit at the point where you wish to measure
current.
7.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.
8. Apply power to the circuit.
9. Read the current in the display.
