3.7. Capacitance measurement
• Insert the black multimeter probe into “COM” end, and the red multimeter probe into “VΩHz” end;
• Select the knob to proper capacitance range,
Notes
• If the capacitance under tested is over the max. Value of selected range, LCD displays “OL”, thus should
select the knob to a higher range.
• When measuring at large capacitance range, if capacitor is crept badly or broken, LCD displays a value
and it’s unstable.
• Tested capacitor shall be completely discharged, for fear of damaging the instrument;
• Unit: 1uF=1000nF 1nF=1000pF
3.8. Frequency measurement
• Insert test leads or shielded cable into “COM” and “ V/Ω/Hz” terminal.
• Select the knob to the frequency range, insert the test leads or shielded cable to the signal source or the
load which is tested.
Notes
• The meter can still work if the input value is higher than 10Vrms, but the accuracy is not guaranteed.
• In noise environment, you’d better use shiel cable to measure a low signal.
• Don’t input voltage higher than 250V DC or AC peak value, or it may damage the meter.
• Never contact the high-voltage circuit measured.
3.9. Diode and on-off test
• Insert the black multimeter probe into “COM” hole and red multimeter probe into “VHz” hole (the
polarity of red multimeter pole is “+”;
• Rotate the functional switch to “DIODE” or “BUZZ” level;
• Measurement in forward direction: Connect the red/black multimeter probe to the positive/ negative
pole of the tested diode, and the display unit will display the approximate value of the voltage drop in
forward direction of the diode;
• The buzzer sounds if the resistance of a circuit under test is less than (50±20)Ω.
Notes
• Don’t input voltage at
level.
3.10. Temperature measurement
• Select the knob to the „°C” range, insert the cathode (black pin) of cold end (free end) of thermocouple
into ”COM” jack, anode (red pin) into “VΩ” jack, put the working end (temperature measurement port)
