Mini-AT User Guide
Default Meter Reader Display
While in the Meter Reader Mode, the Mini-AT continues to recognize and accumulate meter input pulses. Also,
1-minute and 10-minute Time-outs are used to automatically return the instrument to the Corrector Mode. By
design, the Corrector Mode requires much less electrical energy than all other operating modes. The time-out
periods are safeguards to insure that the batteries are not needlessly wasted.
Refer to figure 15 on page 50 which is a flowchart of the default meter reader list. After the initial mag wand
input, the Mini's operating program determines if there are any active alarms. The presence of active alarms,
while in the Corrector Mode, is indicated by displaying all decimal points in the corrected volume display. If there
are active alarms, all active alarm codes are displayed before the normal meter reader list items are displayed.
Note:
While in the alarm display routine, all alarms will be cleared, if the instrument is allowed to time-out (60
seconds) during the display of the "E.E.E.E.E.E.E.E" and Item Code 128 is set to "Yes". If the instrument
receives a mag wand input during the "E.E.E.E.E.E.E.E" display, the alarms are not cleared and the sequence
moves to the "Display Test" display.
The "Display Test" should always be configured as the first meter reader list item. It provides a visual means of
verifying that all LCD segments and decimal points are fully functional. If the "Display Test" does not appear
as in figure 14 on page 49, the remaining item code values may not be accurate.
When the Mini-AT receives a mag wand input during the "Display Test", the current value for Uncorrected
Volume is displayed. Each additional mag wand input will cause the next item code value to scroll onto the LCD.
The items assigned to the default meter reader list are comprised of Item Codes 130-135, 129 and 75-83.
Listed below is the default Mini-AT meter reader list in the proper sequence:
