This symbol is displayed during the test and blinks.
●
This symbol is displayed when the test is paused and blinks.
Click the "Test" key to enter the test state; click "Pause" key to enter the pause state; Under the test
state, the instrument can only switch the display screen, but cannot save data, print,upload and
perform other functions. Under the pause state, the screen will display "Save", "Print", “Upload"keys,
and the users can save, print,upload and perform other operations.
7.3.4 Test Data Specification
●
System
frequency
:
The
upper
right
corner of the screen shows the frequency of the
system collected by the instrument.
●
Three phase voltage angle
: Three phase
simultaneous measurement shows three-phase
voltage angle Φa-b, Φb-c and Φc-a; single-phase
measurement does not display those angles.

●
Ux
: The reference voltage effective value contains only the fundamental wave and the 3, 5 and 7
harmonics
，
the formula is:
Ux = U1
2
+ U3
2
+ U5
2
+ U7
2
When using an induction test mode, the Ex is shown to indicate the electric field induced intensity,
and the unit is KV/m.
●
U1:
fundamental voltage effective value; When using induction testing mode, E1 is shown to indicate
the fundamental electric field induced intensity.
●
U3, U5, U7:
3, 5 and 7 harmonic voltage RMS and their relative content of fundamental voltage;
When using induction test mode, the screen displays E3, E5 and E7.
●
Ix
: full current RMS,only including the fundamental wave and 3, 5, and 7 harmonics.
●
Ixp
: full current peak, namely the peak value of Ix.
●
Ir
: the resistance current RMS, including only the fundamental wave and the 3, 5 and 7 harmonic
resistance currents.
●
Irp
: peak of resistance current, namely the peak value of Ir.
●
Ir1p
: peak of fundamental wave resistance current.
