Operation
Use the push button to page through the individual displays. When doing
so a differentiation is made between short and long button presses. With a
short button press (<3 seconds) you get to the next display within a loop;
with a long button press (>3 seconds) you get to the next display loop.
The "Energy" window (sequence 1.1) of the main loop is the basic display.
If the button is not pressed for approx.4 minutes, the meter automatically
switches off the display to save power (exception: an error exists). If you
press the button again, the meter returns to the basic display.

Display Error codes
If an error occurs, the error code is displayed in the main loop. All win-
dows, however, can still be accessed by pressing the button. If the button
is not pressed for approx. 4 minutes, the error code is automatically dis-
played again.
The error message automatically disappears as soon as the source of the
error is corrected. All errors that exist for longer than 6 minutes, are saved
in the error memory.
