Clamp meter
- On 20M range, the meter may take a few seconds to stabilize reading. This is normal
for high resistance measuring.
- When the input is not connected, i.e. at open circuit, the figure "OL" will be displayed
for the overrange condition.
3.2.5 Diode Test
To avoid electrical shock and/or damage to the instrument, disconnect circuit
power and discharge all high-voltage capacitors before testing diodes.
- Set the rotary switch to
- Press the yellow key once to activate Diode Test.
- Connect the black and red test leads to the COM and V terminals respectively.
- For forward-bias readings on any semiconductor component, place the red test lead on
the component's anode and place the black test lead on the component's cathode.
- The meter will show the approx. forward voltage of the diode.
3.2.6 Continuity measurement
Before taking any in-circuit measurement, remove power from the circuit being
tested and discharge all capacitor in the circuit.
- Set the rotary switch to
- Press the yellow key twice to activate Continuity Check.
- Connect the black and red test leads to the COM and V terminals respectively.
- Connect the test leads to the resistance in the circuit being measured.
- When the test lead to the circuit is below 75, a continuous beeping will indicate it.
Note:
- Continuity test is available to check open/short of the circuit Continuous beeping.
3.2.7 Temperature measurement
To avoid electrical shock and/or damage to the instrument, do not apply more
than 250VDC or 250VAC rms between the ºC terminal and the COM terminal.
To avoid electrical shock, do not use this instrument when voltages at the
measurement surface exceed 60V DC or 24VAC rms.
To avoid damage or burns, do not make temperature measurements in microwave
ovens.
- Set the rotary switch to ºC range and the LCD will show the current environment
temperature.
- Insert 'K' type thermocouple into the COM terminal and ºC terminal. Takings care to
observe the correct polarity.
- Touch the object with the thermocouple probe for measurement.
- Read the stable reading from LCD.
