lists the required equipment.
Table 20. Required Equipment for Inductance Calibration
Equipment Description
LCR Meter
BNC (M) to BNC (M) 4W lead set for LCR
BNC (F) To Single Banana Plug
To calibrate the Inductance function:
1.
Remove the Guard Ground strap on the Product.
2. Set the LCR meter for Ls Mode, Level 1V, Freq 1 kHz, Speed Slow.
3. Complete OPEN/SHORT compensation of the LCR meter and lead set including the banana to bnc
plugs. Do not connect a strap between the Guard and Ground terminals of the DUT for this
function.
4. Connect the LCR meter to the product for four-wire inductance measurements.
5. Starting at step 1, Table 21, set the LCR meter for the recommended frequency (the Product can
be verified at frequencies other than the specified, but the measured output varies within the
specifications as a function of the frequency).
6. Select the appropriate mode (Ls or Lp).
7. Output each value from the Product. Measure with the LCR meter and record in Table 21.
