Switching On The Meter; Select Measuring Function; D) Select Measuring Frequency - VOLTCRAFT LCR-400 Bedienungsanleitung

b) Switching on the meter
Before working with the meter, you have to insert the enclosed batteries. Insertion and changing
of the batteries is described in the chapter "Cleaning and maintenance".
The multimeter can be turned on and off using the operating button (2). Press the button briefly once to switch the
measuring unit on or off. Always turn the meter off when it is not in use. Deactivation is displayed with "OFF".
After activation, the measuring device is in smart AUTO-LCR mode. The last measurement frequency at the time
when the meter was turned off will be used when the meter is turned on again.
In this mode, the device independently measures the most plausible measured values according to fixed param-
eters.
The following parameters are specified:
Parameter
θ < 11°
θ > 11°
θ < -11°
C < 5 pF
c) Select measuring function
The measuring function is selected by the button "L/C/R/DCR". Every time the button is pressed, the next measuring
function is selected. The following functions can be selected in sequence:
AUTO LCR Smart auto mode for L, C and R
L Measuring range inductivity; the subdisplay shows quality factor "Q"
C Measuring range capacity; the subdisplay shows dissipation factor "D"
R Measuring range alternating current resistance
DCR Measuring range direct current resistance
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 capacitive. If a negative
measured value is displayed in measuring mode "R", there is a calibration error.
In this case, perform recalibration.

d) Select measuring frequency

The measuring frequency can be changed manually, but the impedance measuring ranges are frequency-depend-
ent. To change, push the button "FREQ" (9). Every push changes the frequency value in a specified step width:
100 Hz, 120 Hz, 1 kHz, 10 kHz, 100 kHz.
