Select Measuring Function; Select Measuring Frequency - VOLTCRAFT LCR-300 Mode D'emploi

In this mode, the device independently measures the most plausible measured values according to
fixed parameters. The following parameters are specified:
Parameter
θ < 11°
θ > 11°
θ < -11°
C < 5 pF

7.3. SELECT MEASuRINg fuNCTION

The measuring function is selected by the button "FUNC". Every time the button is pressed, the next
measuring function is selected. The following functions can be selected in sequence:
AUTO LCR
AUTO L – Q
AUTO C – D
AUTO R
DCR
The measured values in L, C and R measuring operation may be positive or negative.
If the main measured value in mode "L – Q" is negative (prefix "-"), the measured component is
inductive.
If the main measured value in mode "C – D" is negative, the measured component is capacita-
tive.
If a negative measured value is displayed in measuring mode „R", there is a calibration error. In
this case, perform recalibration.

7.4. SELECT MEASuRINg fREQuENCY

The measuring frequency can be changed manually, but the impedance measuring ranges are
frequency-dependent. To change, push the button "FREQ" (12). Every push changes the frequency
value in a specified step width: 100 Hz, 120 Hz, 1 kHz, 10 kHz, 100 kHz.
