(13) Repeat technique of (9) through (14) above for remaining TI ranges and modes
that require adjustment.
(14) Exit CAL menu by pressing [QUIT] 2 times.
(15) Disconnect equipment set-up.
e. DC Current Adjustments
NOTE
Just one range may be adjusted if required, but for a full
adjustment, start with the 200 μA range and work up to the
20 A range. Zero cal point on all ranges requiring adjustment
may be completed before any range gain adjustments to avoid
multiple connect/disconnects. Any range requiring adjustment
must have all three adjustments: Zero, Range Gain + and
Range Gain .
(1) Set the rear panel CALIBRATION switch to ENABLE (if necessary).
(2) Ensure that table 13 is populated with the values obtained in appendix A
(table A-4) for the ranges requiring adjustment.
(3) Ensure that nothing is connected to all INPUT binding posts.
