4. Connect the test leads to the source being 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.
1. Set the rotary switch in the “Ω ” position.
2. Press “SELECT” to choose the diode or continuity measurement mode.
3. Connect the red test lead to “VHz” jack and the black one to the
“COM” jack.
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.
10.6 FREQUENCY AND DUTY CYCLE MEASUREMENT
Do not conduct frequency or duty cycle measurements on live
circuits.
1. Set the rotary switch in the “Hz” position.
2. Press “Hz%” to choose the frequency or duty cycle measurement
mode.
3. Connect the red test lead to “VHz” jack and the black one to the
“COM” jack.
4. Connect the test leads to the source being measured and read the LCD
display.
10.7 TEMPERATURE MEASUREMENT
1. Set the rotary switch in the “°C/°F” position.
2. Press “SELECT” to choose the Celsius or Fahrenheit measurement
mode.
3. Connect the red banana plug to the “VHz” jack and the black plug to
the “COM” jack.
4. Connect the banana plugs to the source being measured and read the
LCD display.
10.8 DATA HOLD
Press “ ” to lock the displayed value. Press again to exit.
