Specifications
The following tables list the 5520A specifications. All specifications are valid after allowing a warm-up period of 30 minutes, or twice the time
the 5520A has been turned off. (For example, if the 5520A has been turned off for 5 minutes, the warm-up period is 10 minutes.)
All specifications apply for the temperature and time period indicated. For temperatures outside of t
cal
±5 °C (t
cal
is the ambient temperature
when the 5520A was calibrated), the temperature coefficient as stated in the General Specifications must be applied.
The specifications also assume the Calibrator is zeroed every seven days or whenever the ambient temperature changes more than 5 °C. The
tightest ohms specifications are maintained with a zero cal every 12 hours within ±1 °C of use.
Also see additional specifications later in this chapter for information on extended specifications for ac voltage and current. The dimensional
outline for the 5520A Calibrator is shown in Figure A.
