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"
1.
jack.
2. Set the rotary switch to
points of circuit, if the resistance between two points less than
50Ω±30Ω, the inbuilt buzzer will be sounded
NOTES
1. Even without buzzer sounds, voltage may still exist. Do not rely solely
on non-contact voltage detection to determine the presence of voltage.
Detection operation may be subject to socket design, insulation
thickness and different type and other factors.
2. When the meter input terminals detect voltage, due to the influence of
present voltage, the voltage sensing indicator may also light.
3. Keep the appliance away from electrical noise sources during tests, i.e.
fluorescent and dimmable lights, motors, etc. These sources may
trigger NCV detection and invalidate the test.
10.6 DATA HOLD
In any range, short press
appear on the display. Short press

range, place the red test lead on the
range and touch the test leads to both
/H to lock the display value. The H sign will
/H again to exit.
