Direction
..................... setting the sign of phase values in terms of rotation in vector
diagram; values are either
Clockwise
or
Anticlockwise
.
Relation
....................... setting the relation of current phase values; either current phase is
relative to voltage phase in given channel
(Relative)
or it is
Absolute
and measured against 1
st
voltage channel
APPARENT POWER MEAS
.... Settings of the way of calculation of overall apparent power
Method
........................ there are two methods of apparent power calculation:
-
Scalar
𝑆
𝑡𝑜𝑡𝑎𝑙
= 𝑆1 + 𝑆2 + 𝑆3
-
Vector
𝑆
𝑡𝑜𝑡𝑎𝑙
= √𝑃
2
+ 𝑄

Control keys:
F1, ESC
...... Exit (return to previous page)
F3
.............. Load default values (only for parameters in shown page!)
F4
.............. Save parameter values of all Measurement Settings screens into memory
F5
.............. Switching between screens 1/3, 2/3 and 3/3
5.7.2 Test Settings
These pages contain parameters of testing mode.
Test Settings screen 1/3
* P45

METER ERROR TEST
............ Settings of meter testing
Sample type
................
determines the way of collecting samples, it’s either
Impulses
(
Integration time
item is deactivated) or
Int. time
(
No. of impulses
item is deactivated) or
Time&Imp
when both
Impulses
and
Time
can
be defined (both must be fulfilled to obtain one sample)
Integration time
.......... minimum time between two measured error values of meter
[in seconds]
No. of impulses
.......... Number of pulses required to calculate one sample
