3.6.1 Display Screens (Optional Display)
The PPXIITD can display several per-phase and total quantities for the circuit being
monitored. In order to make all quantities available, the display scrolls from quantity to
quantity approximately every 5 seconds. The quantities are refreshed once a second.
The Alphanumeric display at the bottom of the instrument indicates to the user what
quantity is being displayed. The Alphanumeric display also provides the user with
primary engineering units (Watts, kWatts, MWatts, etc.). Listed in Appendix A4 are
standard screens available in the PPXIITD. Configurable screen enable settings allow
the user to enable or disable each of the display screens, in order to view only a
selected subset of all the measurements the meter is capable of displaying. Refer to
the A3 on Setup Mode for instructions on programming Screen Enable Settings (Setup
