TESTING OF SINGLE PHASE ENERGY METER FOR ACCURACY TEST GENERAL DESCRIPTION Error Display Unit is Mircocontroller based unit for calculating error in energy meters. It accepts pulses from Reference Standard Meter and from Meter Under Test and displays error. Accordingly, PASS or FAIL LED glows to indicate whether the meter error is within allowable limits or not. Meter constants of both the meters and Error Limits are programmable and can be set through keys provided on front plate. FEATURES / SPECIFICATIONS 1. Micro Controller based System |

ELEKTRONIKS have developed an accuracy test unit for energy meters.
This facilitates the Energy Meter Manufacturers to test and adjust
the calibration accuracy within a band. This is Low Cost Solution
for accuracy check with internal Reference Standard. The error
calculation and reference standard meters are designed using latest
microcontroller based technology. Essentially, it is a variable
power source which is connected to both Reference Standard Meter
and Meter Under Test. The pulses from Reference Standard Meter
and Meter Under Test are fed to the Error Display Unit programmed
for specific parameters. It compares the energy registered by
Reference Standard Meter and Meter Under Test and calculates the
error. The error is displayed on Digital display in percentage
with resolution of 0.01.
