Negative readings of kvarh net
f
To get block interval demand readings, specify the number of demand periods equal to 1
(see Table 5-2)
g
When the 4LN3 or 3LN3 wiring mode is selected, the voltages will be line-to-neutral; for any
other wiring mode, they will be line-to-line voltages.
(P) available in the PM130P and PM130E
(E) available in the PM130E
NOTE
Writing a zero to one of registers 280-286 causes reset of all maximum demands.
Writing a zero to one of registers 287-294 and 301-302 causes reset of all accumulated
energies.
