Performing the Measurement
Once all the settings have been carried out and checked, the measurement can be
started with the menu item
.
If this is the first measurement after switching on the device or if the calibration values
were reset before the measurement (see previous page), calibration will be carried out
right after the start in order to set the preset maximum measuring current. A
corresponding notice will appear on the display.
Depending on the settings, the individual measurements will take place either in quick
succession (depending on the measuring current 2 to 10 seconds) or at 15 minute
intervals, switching between the involved phases.
The following measured values are shown on the display and continually updated during
the running measuring process as standard.
Using the
menu item during and after the measurement, the diagram types may be
switched between as follows:
R/X
Impedance resistance and reactance
|Z|/Phi
Impedance amount and phase shift angle
U/I
Current and voltage curve of the period in which the measurement took place
The measurement will end automatically as soon as the preset number of
measurements or the preset measurement time has been reached. The measurement
can be manually deactivated at any time via the
menu item.
