VARs When the Power Factor approaches 0.0, the Watts output uncertainty becomes unrealistic because the dominant
characteristic is the VARs (volts-amps-reactive) output. In these cases, calculate the Total VARs Output Uncertainty, as
shown in example 3:
Example 3 Output: 100 V, 1 A, 60 Hz, Power Factor = 0.174 ( =80)
Voltage Uncertainty Uncertainty for 100 V at 400 Hz is, 150 ppm + 2 mV, totaling:
-6
100 V x 190 x 10 = 15 mV added to 2 mV = 17 mV. Expressed in percent:
17 mV/100V x 100 = 0.017 % (see "AC Voltage (Sine Wave) Specifications").
Current Uncertainty Uncertainty for 1 A is 0.05 %  100 A, totaling:
1 A x 0.0005 = 500 A added to 100 A = 0.6 mA. Expressed in percent:
0.6 mA/1 A x 100 = 0.06 % (see "AC Current (Sine Waves) Specifications").

Additional Specifications

The following paragraphs provide additional specifications for the 5522A 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 5522A 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.

[1] With REF CLK set to ext, the frequency uncertainty of the 5522A is the uncertainty of the external 10 MHz clock 5 Hz. The
amplitude of the 10 MHz external reference clock signal should be between 1 V and 5 V p-p.

[1] The maximum frequency of the harmonic output is 30 kHz (10 kHz for 3 to 5 V on the Aux terminals). For example, if the
fundamental output is 5 kHz, the maximum selection is the 6th harmonic (30 kHz). All harmonic frequencies (2nd to 50th) are
available for fundamental outputs between 10 Hz and 600 Hz (200 Hz for 3 to 5 V on the Aux terminals).
