VARs When the Power Factor approaches 0.0, the watts output specification becomes unrealistic because the dominant
characteristic is the VARs (volts-amps-reactive) output. In these cases, calculate the Total VARs Output Specification, as
shown in example 3:
Example 3 Output: 100 V, 1 A, 400 Hz, Power Factor = 0.174 (Φ=80), 1-year specifications
Voltage Specification Specification for 100 V at 400 Hz is, 0.15 % + 18 mV, totaling:
100 V x 0.0015 = 150 mV added to 18 mV = 168 mV. Expressed in percent:
168 mV/100 V x 100 = 0.168 % (see “AC Voltage Specifications”).
Current Specification Specification for 1 A at 400 Hz is 0.24 % + 1200 μA, totaling:
1 A x 0.0024 = 2400 μA added to 1200 μA = 3.6 mA. Expressed in percent:
3.6 mA/1 A x 100 = 0.36 % (see “AC Current Specifications”).
VARs Adder VARs Adder for Φ = 80 at 400 Hz is 0.50 % (see “Phase Specifications”).

Unpacking and Inspection
WXWarning
The Calibrator is capable of supplying lethal voltages. To avoid
electric shock, do not touch the Calibrator’s output terminals.
Read this section before operating the Calibrator.
The Calibrator is shipped in a container that is specially designed to prevent damage
during shipping. Inspect the Calibrator carefully for damage, and immediately report any
damage to the shipper. Instructions for inspection and claims are included in the shipping
container.
If you need to reship the Calibrator, use the original container. If it is not available, you
can order a new container from Fluke by identifying the Calibrator’s model and serial
number.
When you unpack the Calibrator, check for all the standard equipment listed in Table 2.
Report any shortage to the place of purchase or to the nearest Technical Service Center.
Visit Fluke web site for Service Center locations.
If performance tests are required for your acceptance procedures, refer to Chapter 7 of the
5080A Operators Manual for instructions. Line power cords available from Fluke are
listed in Table3 and illustrated in Figure 2.
