10.3 RESISTANCE MEASUREMENT
Do not conduct resistance measurements on live circuits. Make sure
all capacitors in the circuit are depleted.
Set the rotary switch in the desired "Ω
1.
Connect the red test lead to the "VHz" jack and the black test lead to
2.
the "COM" jack.
3. Connect the test leads to the resistor to be measured and read the
LCD display.
10.4 CAPACITANCE MEASUREMENT
Do not conduct capacitance measurements on live circuits. Make
sure all capacitors in the circuit are depleted.
1. Connect the red test lead to the "VHz" jack and the black test lead to
the "COM" jack.
2. Set the rotary switch in the appropriate "
3. Connect the test leads to the source to be measured and read the LCD
display.
10.5 DIODE AND CONTINUITY TEST
Do not conduct diode or continuity measurements on live circuits.
Make sure all capacitors in the circuit are depleted.
Connect the red test lead to the "VHz" jack and the black one to the
1.
"COM" jack.
Set the selector switch to the desired "
2.
3. Press SELECT to choose the diode or audible continuity measurement.
4. For measuring the diode, connect the red test lead to the anode of the
diode to be tested and the black test lead to the cathode of the diode.
The approx. forward voltage drop of the diode will be displayed.
For measuring continuity, connect the test leads to two points of the
circuit to be tested. If continuity exists, the built-in buzzer will sound.
