АМM-3320
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.
Note: In order to avoid damaging the instrument, the capacitance requires discharge before measuring.
3. Frequency setting
Press FREQ key to select frequency value： 100/120/1k/10k/100kHz. The LCR impedance scale ranges are depended on the test
frequency.
4. Data hold
Press this key to hold the measurement data and press it again to resume the measurement.
5. 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 * 100%.
Press REL% key again to show the current readings on primary display and the "REL" symbol will be blinking. The
percentage range is from -99.9% ~ 99.9%. When the present value is larger than double of initial value, the "OL%" indication
will be shown on the secondary display.
During relative measurement, analog bar is always indicating the present measurement value but not the relative value.
