2 DESCRIPTION OF BASIC FUNCTIONS
2.1 READINGS DISPLAYING
The device has LED indicator on a faceplate for visual displaying of the readings (fig. 2). Readings are
displayed in cubic meters up to the fourth decimal point on a cumulative total.
During the operation of the meter, the number of packets sent over the radio channel is displayed
on the LED indicator every 2 minutes, while the "SP" symbol is displayed in the most significant bit (on the
far left).
Optical port
LED indicator
When the meter is turned on for the first time, the following parameters are displayed one by one
on the LED indicator (each one for the 5 seconds):
• name of the built-in software of the meter;
• software version number;
• software ID (check sum);
• method of check sum calculation;
• serial number of the meter in the "SХХХХХХХХ" format (for example, "S40488568");
• date of the meter verification in the "Id dd.mm.yy" format (for example, "Id 01.01.20").
2.2
METER'S OPERATION MODES
To optimize energy consumption, the meter has two operation modes:
• "Storage" - the metrological part works (the meter measures the volume and displays the
accumulated water consumption in cubic meters), the communication part does not work (the
meter does not transmit data via the radio channel). In the "Storage" mode, the LED indicator
displays readings in the "СХХХХ.ХХХХ" format (for example, "С0008.7802");
• "Operation" - the metrological and communication parts work.
The meter is supplied by default in the "Storage" mode, to remove from which it is necessary to
bring the external magnet for 15-20 seconds to the area of reception of the external magnetic field, see
p.2.5.
