30 CENTRON® OpenWay™ Meter Technical Reference Guide

Test Mode

The meter can be placed into Test Mode through software communications.

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 restored when Test Mode is exited.

Test Mode Timeout

If the meter is left in Test Mode, the meter will automatically exit after a user-configurable

Mode Timeout. This action prevents someone from accidentally leaving a meter in Test

Mode and thus losing billing data.

Display Modes

The OpenWay 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

OpenWay 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.
