Test Mode
The meter can be placed into Test Mode either by pressing the TEST button or through
software communications. Manual use of the TEST button can be disabled via PC-PRO+
Advanced software.
If the TEST button is disabled through programming, the meter will not enter Test
Mode when the button is pressed.
While in Test Mode, the TEST annunciator is displayed on the LCD. When the Test Mode
is activated, all billing registers and certain non-billing registers are preserved in non-
volatile memory and are restored when Test Mode is exited.
To exit Test Mode, press the TEST button. The LCD will display " nordiSP" (normal
display) signifying the exit of Test Mode and entry into Normal Mode operation.
Test Mode Timeout
If left in Test Mode, the meter will automatically exit after a user-configurable Mode
Timeout. A programmable timeout length from 1 to 255 minutes is available. 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 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.
Displays
The CENTRON meter features a versatile ANSI C12.10 compliant, 104 segment liquid
crystal display (LCD). A nine-digit LCD, with a variety of annunciators, is provided on
these multifunction personality modules.
