9.4 Measuring with PI1
Torque, rotational speed and mechanical power are measured in
real-time and averaged. They are combined with the measured
electrical values so that slip and mechanical efficiency can be
calculated.
 The device must be equipped with a PI1 process interface
 Menu item PI must be shown in the menu bar
If the analyzer is equipped with a process interface, menu item PI
is shown automatically in the menu.
 Press the measuring key for numerical display.
The measured values of channel 1 are shown.
