Current Measurements
1. Set the Function/Range switch to the highest 700A ac range.
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 200 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 desired 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.
WARNING
The accuracy of the functions might be slightly affected, when exposed to
a radiated electromagnetic field environment, eg, radio, telephone or
similar.
