4.
Read the resistance in the LCD display
Notes
•
If display "OL" for over range, set the rotary switch to higher range. For
measuring over 40MΩ 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.
1.
Set the rotary switch to
on the display / press "FUNC" button to indicate
display.
2.
Insert the black test lead banana plug into the negative COM jack,
insert the red test lead banana plug into the positive V jack.
3.
Place the red test lead on the anode of diode and black test lead on the
cathode of diode, the meter will show the approx. forward voltage of
diode, reverse voltage will indicate OL.
4.
Touch the test probe tips to the circuit or wire you wish to check, the
max. value of resistance under check will be showed in display, if the
resistance is less than 30Ω, the audible signal will sound.
10.5 CAPACITANCE MEASUREMENT
Do not conduct capacitance measurements on live circuits. Make
sure all capacitors in the circuit are depleted.
1.
Set the rotary switch to
nF on the display.
2.
Insert the black test lead banana plug into the negative COM jack,
insert the red test lead banana plug into the positive V jack.
3.
Touch the test leads to the capacitor to be tested and read the
capacitance value in the display.
Notes
1.
The test may take more time for large capacitors to charge, wait until
the readings settle before ending the test.
