7.3. Auto LCR smart mode
Note:
In order to avoid damaging the instrument, the capacitance
requires discharge before measuring.
* The default test mode is Auto LCR mode which could
check the type of impedance smartly.
If |θ|<11°, the Auto-R mode is selected. The parameter on
*
sub-display is θ.
If θ > 11°, the Auto-L mode is selected. The parameter on
*
sub-display is Q.
If θ < -11°, the Auto-C mode is selected. The parameter on
*
sub-display is D.
* If the C < 5pF, the parameter on sub-display is parallel
resistance Rp.
7.4. Frequency setting
Press FREQ key to select frequency value：
100/120Hz/1/10/100kHz. The LCR impedance scale ranges
are depended on the test frequency.
7.5. Data hold
Press this key to hold the measurement data and press it again
to resume the measurement.
7.6. Relative mode
During relative measurement the meter remembers the current
readings on primary display (called initial value) when pressing
the REL% key, and "REL" symbol appears on LCD. The
secondary display will show the percentage of relative value
REL%.
The REL% = (present value –initial value) / initial value x 100%.
