4. Diodes Measurement (see diagram 5)
1) Turn rotary switch to “
”
2) Insert the red test lead into the “ ” terminal and the black test lead into the “COM” terminal. Red test lead is “+” Black test
lead is “-”.
3) In a circuit, a good diode should still produce a forward voltage drop reading of 500 ~ 800mV. However, the reverse voltage
drop reading can vary depending on the resistance of other pathways between the probe tips.
Warning:
• The LCD display “OL” indication open-circuit of the tested diodes or the testing the diodes with polarity.
• To maintain the diodes measurement accuracy disconnect circuit power and discharge all the high voltage
capacitors during the measuring resistance.
• The open circuit of diodes is 2.3V.
• Do not input higher than DC 60V and AC 30V voltage to prevent any damage and accident.
5. Temperature Measurements (see diagram 7)
1. Turn rotary switch to “C”
2. K-type point contact temperature probe can only be used in the measurement below 230°C, you need to separately buy
another temperature probe.
3. The LCD displays “OL” indicating point contact temperature probe which take off. When short circuit between terminal and
COM terminal, the meter show the value of room temperature.

• Take off and well keep the point contact temperature after the measurement.
