Display and coordinate system
The main totalizer is displayed in normal operating mode. The other display values
can be selected with the operating buttons. After approx. 1 minute, the TME400
switches back to the main totalizer.
If the display is dark, the TME400 is in energy-saving mode, where the display is
completely switched off. The incoming pulses are processed and the outputs are ac-

The display value is shown again by pressing any operating button.
Any arbitrary position in the coordinate system, which is identified by letters and num-
bers, can be reached with the arrow keys.
