When upper limit of the indication range is exceeded, it is in-
dicated by two horizontal lines in upper part of the display.
Conversely, when lower limit is exceeded, it is indicated by two
horizontal lines in the lower part of the display. When mean
power is measured ΣP
for 15-second quantum. Depending on chosen value (15 min, 30
min, 60 min) calculated mean value is based on 60, 120 or 240
measurements. After the meter is turned on or after the power is
reset, the first value will be calculated in 15 seconds after turning
meter on or resetting. until all probed values of the active power
are acquired, mean power value is calculated from values already
measured. Current in the neutral wire I(N) is calculated from
phase current vectors.
When alarms are activated, symbols A1 and/or A2 are displayed.
When alarms are deactivated and alarm signalization latch is
turned on, flashing symbols A1 and/or A2 are displayed.
