2.
Set the rotary switch to the current range and touch the test lead
probe tips to the circuit under test, the red test lead connection will be
displayed.
Notes
•
Set the rotary switch to higher range if not known the current range
under test, and then lower down until the best accuracy.
•
If display"OL" for over range, set the rotary switch to higher range.
•
Indicates the max current is 200mA or 10A based on jacks the red test
leads to be inserted, fuse will be blown out at over-range current.
10.3 RESISTANCE MEASUREMENT
Do not conduct resistance measurements on live circuits. Make sure
all capacitors in the circuit are depleted.
Insert black test lead into "COM" jack, and red test lead into "VΩmA"

resistance and read the value from LCD.
Notes
If display "OL" for over range, set the rotary switch to higher range. For
•
measuring over 1MΩ high resistance, the meter may take a few seconds
to stabilize the readings.
In the open circuit, the meter display "OL" to indicate no input.
•
•
To avoid electric shock, disconnect power to the unit under test and
discharge all capacitors before taking any resistance measurements.
10.4 DIODE AND CONTINUITY TEST
Do not conduct diode or continuity measurements on live circuits.
Make sure all capacitors in the circuit are depleted.
Insert black test lead into "COM" jack, and red test lead into "VΩmA"
1.
jack, the polarity of red test lead is "+".
2.
Set the rotary switch to
anode of diode and black test lead on the cathode of diode, the meter
will show the approx. forward voltage of diode.
10.5 CONTINUITY CHECK
Insert black test lead into "COM" jack, and red test lead into "VΩmA"
