OPERATION - AUTOMATIC MEASUREMENT
•
Once the meter is switched on, it defaults to AUTO LCR mode, at the frequency of
1kHz.
•
In auto mode, the meter can automatically check the impedance characteristics of
a tested object and then select L, C or R main parameter, its associated secondary
parameter and the correct serial/parallel mode accordingly.
•
Correspondence between the main and secondary parameter under auto mode:
- Capacitance (C) - Dissipation (D)
- Inductance (L) - Quality Factor (Q)
- Resistance (R) - Phase Angle (θ)
•
Under auto measurement mode, serial/parallel mode is determined based on the
impedance of the tested object.
•
The parallel mode is selected if the impedance is greater than 10kΩ.
•
The serial mode is selected if the impedance is less than 10kΩ.
DATA HOLD
•
Press and hold the
HOLD
button to freeze the data during measurement.
•
Press again to exit and return to normal measurement.
MEASUREMENT PARAMETER UNDER L/C/R MODE
•
Select the corresponding parameters under manual L/C/R mode.
Selection of main parameter:
•
Default status is AUTO LCR once powered on.
•
Select “FUNC” to select parameters of:
“AUTO LCR → AUTO L → AUTO C → AUTO R → DCR → AUTO LCR”.
Selection of secondary parameter:
•
After a main parameter has been selected, press
SER/PAL
to switch between
serial and parallel mode,
•
Press
D/Q/θ
to select “D”, “Q”, “θ”, “ESR” (“ESR” will show if under serial mode
and likewise “Rp” if parallel mode is selected).
•
Under “AUTO R” or “AUTO DCR”, the secondary parameter will be negligible.
Notes:
•
When measuring capacitance <5pF under AUTO LCR mode, “Rᵖ” will show on the
secondary display instead of Dissipation factor (D).
•
Some secondary parameters will not show on the LCD even if you have accessed
“AUTO R”, “AUTO DCR” or “AUTO LCR” mode.
MEASUREMENT FREQUENCY
•
This model can provide five frequency testing points:
100Hz/120Hz/1kHz/10kHz/100kHz.
•
Default frequency is 1kHz, although the user can press
FREQ
to select:
“1kHZ → 10kHz → 100kHz → 100Hz → 120Hz → 1kHz”.
Note: DC impedance is measured under “AUTO DCR” mode and measurement
frequency can be neglected.
