5.3 Meter Error Test
This page enables to perform meter error test by samples gathering. Page is activated by F2 from
Load Values screen or F1 from database (1/5 – 4/5).
Meter Error Test screen
* P10
Content:
U, I ............... Load point values
Parameters ... Parameters of tested meter
SN ................. Serial number of meter (asterisk behind the
SN indicates that at least one from above
parameters is different from meter
parameters defined in database)
Error ............ Actual measured error of meter
Samples ....... Number of measured/required meter errors
Impulses / Integration time ............. number of pulses
(with time) which make one sample
Average ........ Average error
Deviation ...... Standard deviation of measured samples
Parameters of tested meter:
Connection type ............ 3P4W, 3P3W, 2P3W, 1P3W or 1P2W (see Connection Diagrams)
Energy type .................... Active, Reactive or Apparent
Registration mode ........ LED, DISC/SO (SO = pulse output of meter), SNAP. S (=snap switch).
Switching into DISC/SO causes permanent shine of transmitter LED of
OPTS 2100 sensor, so the user can easily set the position of OPTS
2100 before calibration (more information in Accessories Guide Chapter
Optical Sensor)
Constant ......................... Constant of tested meter
Constant Unit ................. i/kWh, i/Wh, i/Ws, i/kWs, kWh/i, Wh/i, Ws/I, kWs/i, MWh/i or i/MWh
(i = pulse or rotation)
CT .................................. transformation ratio of current transformer (can be hidden in Test
settings). Changing this value influences the change of Constant value.
VT .................................. transformation ratio of voltage transformer (can be hidden in Test
settings). Changing this value influences the change of Constant value.
