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).
I n 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.
