Description

The 5077 Series 2 model is a multifunction calibrator for sourcing AC/DC voltage

and current, and single-phase power. It can be used as a workload calibrator for

verification of electrical measurement devices, or as a programmable source in an

automated test rig for meter testing.

The series 2 model offers the same coverage as it's predecessor with additional

ranges, front panel operation, and independent voltage and current functions.

This added functionality increases the workload capabilities, whilst maintaining

performance for dedicated testing of single-phase watt-meters, power meters, and

kW-Hr meters.

For power the 5077 voltage range is 2 mV to 1050 V, with current from 2 mA to 22 A.

Frequency is adjustable from 40 to 500 Hz, and phase ± 90.0° in 0.1° steps.

Alternatively power factor (PF) can be set in steps of 0.01. The output can be

displayed as VA or Watts. The wide current and voltage ranges enable verification

of power meters on either the primary side of the of the CT / VT or directly connected

to the meter (secondary side).

The standard maximum AC current output (22 A) can be extended to 100 A by using

an optional 100 A current transformer (model 9790). This extends the maximum

power to 0.1 MW/MVA. A single and 50-turn current clamp adaptor (model 9780) is

available for clamp sensor and meter calibration up to 1000 A. The 5077 features

turn coil ranges for DC and AC current, designed for use with this adaptor. Further

options include test lead sets, carry case options, and calibration software.

Simple operation

Front panel operation is easy and intuitive. Quickly select functions and ranges, set

output values and increment digits up/down via the keypad. A deviation control

feature enables the user to finely adjust the output value as a percentage

(± 9.999 %). All information is shown on a clear, easy to read alphanumeric display.

Calibrator control software

The calibrator control software provides an advanced user interface with intuitive

operation via a PC or laptop. It enables a fast method of function selection, setting

and output. Quickly adjust and deviate values, and easily select ranges and units

required. A one year license is supplied as standard.
