Changes in the averaging time, cause corresponding changes in the recording
time of the measurement (double averaging time = double recording time).
When the recorder graphics reach the screen margin during recording, a
picture of this screen is saved.
The display is then deleted and the recording is continued. Up to 6 auto
screens are saved in the course of a recording. The saved screenshots can
be retrieved via the "View Auto Screenshots" menu.
Note:
Do not forget to operate the device with the DC adapter during recording in order
to prevent shutdown caused by low battery.
Active and reactive energy are not shown in the recorder function.
Analysing the measured values of the recorder function:
Use of the key <cursor>. When you invoke the cursors you can probe the
graphs and display the associated values. With ´ ´ you can select the
individual phases again.
Recording
In Record mode, the following values are recorded for every phase (L1, L2,
L3)
•
Active power (P)
•
Apparent power (S)
•
Reactive power (Q)
•
Power factor (PF)
•
Cosine
(cos
ϕ
)
•
Power of distortion (D)
These values can be analysed reported and exported with the PQLogView
software.
Note:
The cursor functions are only available in the ”Hold“ mode.
