Inductivity Measurement - VOLTCRAFT LCR-400 Mode D'emploi

b) Inductivity measurement
Make sure that all circuit parts, circuits and components and other objects of measurement are
disconnected from the voltage and discharged.
Switch on the measuring device at the operating button (2).
Select the measuring input for your purpose and perform calibration.
After switching on, the smart "AUTO LCR" mode is always active. Many settings are done by the meter. Of course,
you can also make the settings manually by pushing the buttons "L/C/R/DCR (3) D/Q/ESR" (8), "SER/PAL" (8),
"FREQ" (9). The main display shows the inductivity value, the subdisplay the quality factor "Q".
The measuring frequency can be selected with the button "FREQ" (9). The following values are available: 100 Hz,
120 Hz, 1 kHz, 10 kHz, 100 kHz. Every time you press it, the measured value switches. The measuring frequency
also determines the measuring range.
Switch between serial and parallel modes with the button "SER/PAL" (8). To use this function, AUTO mode must be
deactivated by pushing the buttons "L/C/R/DCR" (3). To return to AUTO mode, push the buttons "L/C/R/DCR" (3) for
approx. 3 seconds.
Connect the measuring object (coil) to the measuring input. After a short time the display shows the inductivity. Wait
until the displayed value has stabilised. This may take several seconds.
Shielded components can be connected to the integrated measuring contacts.
• If "OL" (overload) appears on the display, you have exceeded the measuring range.
• If required, select another measuring frequency with a higher measuring range.
• Remove the measuring lines from the object to be measured after completion of the measurement and switch off
the measuring device.
