Number of Display Patterns and Individual Display Patterns
Allocate desired measurement items to the upper, middle and lower displays of the PR300, respectively, to define
the display view as a single display pattern. It is possible to define a maximum of 8 patterns. For the number of
display patterns, specify how many of these defined display patterns the PR300 should show.
NOTE
● As shown in the table below, some measurement items cannot be measured depending on the type
of phase and wire system. Measurement items that cannot be measured cannot be selected as
options for a display pattern.
● In the case of a three-phase four-wire system, the initial values of Display patterns-1 to 8 can all be
shown on the PR300. For phase and wire systems other than a three-phase four-wire system,
measurement items that cannot be measured are shown as “

*1 For a three-phase four-wire system (2.5 element), it is possible to set the following measurement items
only when the current is in a state of equilibrium:
Current (phase switch indication), Current-1, Current-3, Reactive power, Apparent power, Power factor,
LEAD reactive energy, LAG reactive energy, and Apparent energy.
● The demand value and maximum demand value can only be selected for a PR300 with the demand
measuring function. For a PR300 without the demand measuring function, the initial values of
demand value and maximum demand value are shown as “
