5.5.2.5. Measures
In measure mode, the instrument displays the saved values in TRMS as shown in the
following figures:
In this page, the following symbols are used:
V1N  Neutral - Phase L1 Voltage
V2N  Neutral - Phase L2 Voltage
V3N  Neutral - Phase L3 Voltage
VNPE  Neutral - Ground Voltage
V12  Phase L1 - Phase L2 Voltage
V23  Phase L2 - Phase L3 Voltage
V31  Phase L3 - Phase L1 Voltage
Inv%  % value of the Negative sequence unbalance
Omo%  % value of the Zero sequence unbalance
SEQ  Phase sequence:
”123” => Correct
”132” => Not correct
”023” => No Voltage on B1
”103” => No Voltage on B2
”120” => No Voltage on B3
”100” => No Voltage on B2 and B3
”020” => No Voltage on B1 and B3
”003” => No Voltage on B1 and B2
Hz  Frequency
I1  Current on Phase L1
I2  Current on Phase L2
I3  Current on Phase L3
IN  Neutral Current

The following keys are active on this page:
 The F1 key (or the PAG item on the display) advances to the following page of saved
values.
 The ESC key (or the smart icon on the display) to exit the function and go back to the
“Recording analysis” page (Fig. 124).
In this page, the following symbols are used:
Patt  System total Active Power
Preatt  Total Reactive Power
Papp  Total Apparent Power
Pf  Total Power Factor
CosPhi  System total CosPhi
CosPhi represents the theoretical limit value which
can be reached by the Power factor if all harmonics
are eliminated from the electrical system. For
dimensioning a power factor correction system,
reference is usually made to the CosPhi parameter
value.
