The common measurements display (main screen) does not have an indicator LED. If

no LED is lit up below the display, this means that the common measurement
parameters are being displayed at this time. To return to the common measurements
from another display, just press the same key (the key pointed to by an illuminated
LED) until the illuminated LED goes out.

parameters in addition to the LEDs that show measurement units. Note that phase-to-
neutral volts page (with the “P” label) is displayed only in wiring connections with a
neutral.
