Voltage Measurements
1. Connect the red test lead to the "V" jack and the black test lead to the "COM"
jack.
2. Set the Function/Range switch to the desired voltage range (AC or DC). The
meter will automatically select the best voltage range.
3. Connect the test leads to the device or circuit being measured.
4. For dc, a (-) sign is displayed for negative polarity; positive polarity is implied.
Current Measurements
1. Set the Function/Range switch to the desired highest 700A range (AC or
DC). In DC current measurement use

ZERO button, offset the residual
magnetic of the jaws.
2. Press the trigger to open transformer jaws and clamp onto one conductor
only. Read the current directly on the display. It is recommended that the
conductor be placed at the center of the closed jaws for maximum accuracy.
3. When the reading is lower than 430 counts, set the range switch to the next
lower range position. For maximum accuracy, select the lower range
possible without overranging the meter.
Resistance Measurements
1. Set the Function/Range switch to the resistance range.
2. Remove power from the equipment under test.
3. Connect the red test lead to the " + " jack and the black test lead to the "COM"
jack.
4. Touch the probes to the test points. In ohms, the value indicated in the
display is the measured value of resistance.
