ADJUSTMENT
4. Note capacitance and dissipation factor readout on 4262A display.
5. Rotate 4262A C ZERO ADJ control ccw until capacitance readout on LCR display is
half that obtained in step 4 within a tolerance of £3 counts.
6. Adjust A12C11 until dissipation factor readout becomes double that obtained in step 4
within a tolerance of £2 counts,
Note
Because A12C11 and C ZERO ADJ controls
interact with each other, maintain capacitance
readout obtained in step 5 by controlling C
ZERO ADJ until A12C11 is properly adjusted.
