8.22 MEASURING TEMPERATURE
WARNING
Risk of electric shock.
Do not input a voltage of over DC 30V and AC 60V voltage in the temperature
measurement range to avoid harm or damage to the instrument.
1. Rotate the function range switch to the temperature measurement range (select Celsius
or Fahrenheit as needed).
2. Connect the negative and positive terminals of the K-type thermocouple to the COM
input jack and jack.
8. OPERATING INSTRUCTIONS
20
8.20 DIODE TEST
Warning
Risk of electric shock.
When measuring diodes on a line, make sure that the circuit power is off and the
capacitors on the circuit are fully discharged.
1. Rotate the measuring function selection dial to the Diode position and ensure that the
power to the circuit under test is cut off
2. Press the "SEL" button to select the diode measurement function
3. Connect the black lead to the COM probe socket and the red lead to the VΩ probe
socket.
4. The meter will display the value of the diode under test. If the test polarity is reversed,
the meter will display "OL" this can be used to distinguish between the anode and
cathode diodes.
Note: The instrument shows the forward voltage drop of the measured diode.
8.21 CONTINUITY TEST
Warning
Risk of electric shock.
Make sure the circuit power is off, and the circuit capacitors completely discharged.
1. Rotate the measuring function selector dial to the continuity position and ensure that
the power to the circuit under test is off.
2. Press the "SEL" button to select the continuity measurement function
3. Connect the lead to the COM input jack and red lead to the VΩ probe socket.
4. If the measured resistance of the line is less than 40Ω, the buzzer will sound.
8.23 MEASURING INRUSH CURRENT
WARNING
Risk of electric shock.
Before removing the current clamp, remove the watch from the instrument.
1. Rotate the measurement function selection dial to the appropriate current.
2. Press the trigger to open the clamp, pass the wire to be measured into the centre of the
clamp, and then slowly release the trigger until the clamp is fully closed.
3. Press the "REL / INRUSH" key for more than 2 seconds to enter the inrush current
measurement mode. The LCD displays "- - - -" until the motor is detected.
4. Read the measurement result from the LCD.
