This page enables to perform meter error test. Page is activated by key F2 of Load Values page or F1
from database (2/5
– 4/5).
Meter Error Test screen
* P10
Content:
U, I ................ Load point values
Parameters .. Parameters of tested meter (red color text
indicates that specific parameter is different
from parameters defined for selected meter
in database)
SN ................ Serial number of meter
Error ............ Actual measured error of meter
Samples ....... Number of measured/required meter errors
Impulses / Integration time ... number of impulses for one
sample / minimum time between two
measured error values of meter
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. Value is changing (red color) with the change
of CT ratio, VT ratio and Constant type parameters
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)
