Status
of LED
indicator
RUN
Short flashing – the monitor is performing measurements accor-
ding to the programmed parameterization.
Repeated short flashing – the monitor has been programmed but
is not measuring yet, because the preset time of measurement
start has not come yet or the supply has not switched on due to
programmed measurement with delayed start.
Alternating light 1:1 – oscillographic recording.

Status of
measured
voltages
U1, U2,
U3, U4
Signalization of the status of voltage at the inputs U1, U2, U3
and U4 during measurement at the LV level (Y-connection) or
U1-U2, U2-U3, U3-U1 during measurement at the MV and HV
level (delta connection).
Light:
• constant – voltage is within the preset tolerance range
(0.9 U
n
to 1.1 U
n
)
• one flash – voltage is within the preset range of interruption
• two flashes – voltage is within the preset range of dip
• three flashes – voltage is the preset range of swell.
