1-23. Additional Specifications

The following paragraphs provide additional specifications for the 5520A Calibrator ac
voltage and ac current functions. These specifications are valid after allowing a warm-up
period of 30 minutes, or twice the time the 5520A has been turned off. All extended
range specifications are based on performing the internal zero-cal function at weekly
intervals, or when the ambient temperature changes by more than 5 C.
