7. Set the LCR meter test frequency.
8. Push OPERATE to set the Product to Operate.
9. After the LCR meter measurement settles, input the measurement in the Enter Measurement Value
window on the Product.
10. Complete steps 6 to 9 until you complete all points in the sequence.
11. Alternatively, steps 18 to 22 can be measured with the charge method - follow the instructions in
the calibration verification section.
12. When a section is complete, the Product highlights the following section.
Inductance Calibration Adjustment
The Product begins with a prompt to connect an LCR meter. Do not connect the LCR meter to the DUT
at this time. Proceed as follows.
1. Set the LCR meter for Ls Mode, Level 1 V, Freq 1 kHz, Speed Slow.
2. Complete ZERO/SHORT compensation of the LCR meter and the lead set for four-wire
measurement when the single banana plugs are connected. Do not connect a strap (remove strap)
between the Guard and Ground terminals of the DUT for this function.
3. Connect the LCR meter to the Product for four-wire inductance measurements.
4. For each step, refer to Table 32 for the test frequency setup.
