Note
Settling times mentioned here assume that steps 1 through 32 are followed in sequence. If you
have just calibrated dc volts (steps 1 through 10), but do not follow the subsequent sequence, a
special settling period of 4 minutes may be required due to dielectric absorption caused by the
1
000 V dc input in step 10. Examples of this requirement include re-checking dc volts calibrati
on
(going from step 10 back to step 1) or skipping to ohms calibration (going from step 10 to step
25.)
