5522A
Operators Manual
General Specifications
The following tables list the 5522A specifications. All specifications are valid after allowing a warm-up period of 30
minutes, or twice the time the 5522A has been turned off. (For example, if the 5522A 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 tcal ±5 °C (tcal is the
ambient temperature when the 5522A 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.

2.99999 A are sensitive to storage temperatures above 50 °C. If the
5522A is stored above 50 °C for greater than 30 minutes, these ranges
must be re-calibrated. Otherwise, the 90 day and 1 year uncertainties
of these ranges double.

a drying-out period (with power on) of at least one week may be
required.

and/or fuse protection on the output terminals for all functions. This
protection is for applied external voltages up to ±300 V peak.
Electromagnetic fields of 1 to 3 V/m, resistance outputs have a floor
adder of 0.508 Ω. Performance not specified above 3 V/m. This
instrument may be susceptible to electro-static discharge (ESD) from
direct contact to the binding posts. Good static aware practices should
be followed when handling this and other pieces of electronic
equipment.
Line Frequency: 47 Hz to 63 Hz
Line Voltage Variation: ±10 % about line voltage setting
For optimal performance at full dual outputs (e.g. 1000 V, 20 A) choose
a ling voltage setting that is ±7.5 % from nominal.

standards used for calibration. You do not need to add anything to
determine the total specification of the 5522A for the temperature
range indicated.
