FAIL symbol will show on the primary display. Press CAL key again to save the calibration data.
Note: 1. To get the better accuracy, the open/short calibration should be done before measurement.
2. The purpose of open/short calibration is to reduce the parasitic effect of the test fixture.
3. Open or short circuit, is selected automatically according to the measurement terminal.
4. In short calibration, there may be FAIL situations, which may be caused by not using the low resistance short line or
unreliable contact, please try again after reliable short-circuit
7. Equivalent Circuit
When any L/C/R functional mode is selected, the default measurement in series or parallel mode is auto selected and the AUTO
segment will be shown on LCD display. It depends on the total equivalent impedance measured.
If the impedance is larger than 10kΩ, parallel mode is set and Lp/Cp/Rp is shown on the display.
If it is less than 10kΩ, series mode is set and Ls/Cs/Rs is shown on the display.
When SEL/PAL key is pressed, the impedance measurement will be set in series mode or in parallel mode sequentially.
Note: The actual capacitance, inductance and resistance is not ideal component of pure reactance and pure resistance. Usually
the resistance and reactance exist simultaneously. A practical impedance can be simulate by the ideal resistors and ideal
reactor (inductor or capacitor) in series or parallel form.
8. Sorting mode
The sorting mode could help the user to make a quick sort for a bunch of components. The setting steps as following:
