ELECTRONIC TALLEY ROLL (ETR) FILE
The MV2 is equipped with an Electronic Talley Roll (ETR) feature that stores the weight and a
consecutive transaction number each time the indicator receives a Talley command from the
computing peripheral. The data is maintained in a customer supplied Micro SD card and is
available for use by a weights and measures inspector.
NOTE: The Micro SD card is inserted into the battery charger board under the
right end cap (as viewed from the MV2 back). See Figure No. 12.
CAUTION! Do not plug or unplug the battery charger board while the MV2 has
power (batteries installed or AC power adapter plugged in).
DAMAGE TO THE MICRO SD CARD WILL OCCUR.
When enabled, each time the indicator receives an ETR request (SMA XT command), the
gross weight and an internal consecutive transaction number (that cannot be modified) will be
stored in memory. The ETR file is structured such that when the capacity of the Micro SD card
is reached, the newest transaction will replace the oldest. The ETR file can only be displayed
and cannot be manually cleared or printed.
