Additional Specifications
The following paragraphs provide additional specifications for the 5500A 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 5500A 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. (See Chapter 4,
“Front Panel Operations.”)
