Service Manual
To calibrate the Capacitance function for values <1 mF:
1. Remove the Guard Ground strap on the Product.
2. Set the LCR meter for Cp Mode, Level 1V, Freq 1 kHz, Speed Slow.
3. Complete the OPEN/SHORT compensation of the LCR meter and lead set for two-wire
measurement that includes the Y adapter and single banana 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 two wire capacitance measurements.
5. From step 1, Table 18, set the LCR meter for the recommended frequency (the Product can be
verified at frequencies other than specified, but the measured output varies within the specifications
as a function of the frequency).
6. Select appropriate mode (Cp or Cs).
7. Output from the Product. Measure with the LCR meter and record in Table 18.
