Metering Capabilities Meter Overview
2-16 Meter Overview TM-iX0A-0805
Display Lists
The meter maintains up to four (4) display lists. The contents of each list and the order in which
items appear is configured using iConFig. Each list item is displayed as the meter scrolls through
the list depending upon the meter’s operating Mode.
Normal Display List
When the meter is in Normal Mode, the Normal Display List is displayed. This list usually
contains quantities and data used for customer billing and is the default list displayed when
power is restored (unless the Test Lock feature has been activated – see “Test Mode Lock”
below). This list is displayed after exiting any of the other modes.
In this mode, the meter automatically scrolls through the configured List Items at the
configured rate.
Alternate Display List
When the meter is in Alternate Mode, the Alternate Display List is displayed. This list usually
contains information that is not normally used for customer billing (e.g., site surveys, debugging
the meter, marketing information, future equipment planning). This list is displayed when the
meter is in Normal Mode and the
ALT button is pressed or by way of remote commands from
iConFig.
In this mode, the meter automatically scrolls through the configured List Items at the configured
rate. The meter automatically exits Alternate Mode after the configured timeout expires. When
the timeout is set to zero (0), it will remain in Alternate Mode until the power is removed.
To exit Alternate Mode, press the
ALT button again or by way of remote commands using
iConFig.
Test Display List
When the meter is in Test Mode, the Test Display List is displayed. This list usually contains the
quantities and data that can be used to verify meter calibration. This list is displayed when the
meter is in Normal Mode or Alternate Mode and the TEST button is pressed or using remote
commands from iConFig.
Upon entering Test Mode, the TST Annunciator on the LCD illuminates, and the meter:
• Suspends regular metering
• Stores all of the billing data into non-volatile memory
• Resets all of the Energy and Demand values to zero (0)
In Test Mode, the measured quantities are stored in the Test Mode registers and not in the
customer-billing registers. Use the
RESET button to set all of the metering and demand
quantities in the Test Mode registers back to zero (0) and the
ALT button to manually scroll
through the items in the Test Display List. The meter automatically exits Test Mode after the
configured timeout expires. When the timeout is set to zero (0), it will remain in Test Mode until
the power is removed.
To exit Test Mode, press the
TEST button or use remote commands from iConFig. Upon
exiting Test Mode, the customer-billing data is restored.
