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° 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.

Operation via EasyCal or virtual control software
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.
The 5077-S2 can be utilised as a bench calibrator or for automated test rigs providing signal injection. Users can perform various tasks:
Test AC/DC voltage and current on multimeters, panel meters
Source independent voltage and current into automated tests
Input power into automatic test systems for manufacturing
Virtual Control Software
The new Series 2 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.
It is designed for use with keyboard & mouse, or via touch screen operation. The ease of use makes it ideal for calibration technicians performing test applications with manual procedures, or quick checking functions of measurement devices.
EasyCal Calibration Software
The 5077 can be controlled via Time Electronics EasyCal
software to automate the calibration process. This provides
increased speed of calibration and consistency of results.
Produce traceable calibration certificates and test reports
for quality standards with additional uncertainty information
for ISO 17025 conformance.

* The accuracy of the power is complex and is determined by using a formula, which combines the errors due to Voltage, Current, and Phase.
Power Accuracy (%) = SqrRt (Voltage Accuracy 2
