LCR Measurement
Caution
When a capacitor with big capacitance, fully discharge is
recommended to prevent possible damaging the meter and
expedite the measurement.
1. Set rotary switch to LCR position.
2. Plug black test lead into the COM terminal and red test
lead into the LCR terminal.
3. To get the best accuracy, highly recommend to do
calibration before measurement.
•
Press REL Button to enter calibration mode,
“OPEn”
displays. Open test lead and press REL button to
process open calibration until PASS displays. Press
REL button again,
“Srt” displays. Short test leads press
REL button to process short calibration until PASS
displays the calibration is complete. Press REL
button again to enter LCR measurement.
4. Press SELECT button to choose L or C or R for
measurement. Parallel or series mode and test
frequency (100Hz, 1kHz or 10kHz) is chosen
automatically.
5. Connect the test leads to the component to be tested.
Allow time for the value to stabilize and then read the
value on the LCD.
6. The main display shows inductance, capacitance or
resistance value of components be tested.
7. The parameter of (Q) quality factor, (D) dissipation factor
and (
θ
)
phase angle displays on sub-display.
8. Press
θDQ
button to shift reading the parameter.
•
Q &
θ for inductance measurement.
•
D &
θ for capacitance measurement.
•
θDQ button is disabled for resistance measurement.
