CENTRON® Polyphase Meter Technical Reference Guide
To exit Test Mode, press the TEST button. The meter will change display mode to Test
Alternate. Press the TEST button again. The LCD will display “nor diSP” signifying the exit
of Test Mode and entry into Normal Mode operation.
Test Mode Timeout
If the meter is left in Test Mode, the meter will automatically exit after a user-configurable
Mode Timeout. See the PC-PRO+ Advanced online help for more information on
configuring the Mode Timeout. This action prevents someone from accidentally leaving a
meter in Test Mode and thus losing billing data.
Test Mode Lockout
Activating Test Mode Lockout via the programming software will prevent entry into Test
Mode via manual Test Mode Switch activation.
Display Modes
The D/T/L Register has five display modes as shown in the table below: Normal, Alternate,
Test, Test Alternate, and Toolbox. Each display mode has a separate list of items
(quantities) it can display. The aggregate of items associated with a display mode is called a
display list. Test and Test Alternate modes employ the same display list. The CENTRON
Polyphase meter can display a maximum of 80 items. The display list is dynamically
configured through PC-PRO+ Advanced. The user can select as many items per mode
totaling up to 80 with at least one item in each display mode. The display items and
sequence of display, along with any desired annunciators or ID code number, are selected
during program setup, a feature of the PC-PRO+ Advanced programming software.
