3.5. “End of billing period”
Meter automatically ends billing period at the end of calendar month. Therefore there are a few
possibilities to end billing period manually:
• By pushing button in position “Cumulation/Reset”;
• Sending command via optical interface (communication protocol IEC 62056-21);
• Sending command via electrical interface (communication protocol IEC 62056-31).
When user pushes button “Cumulation/Reset” or sends command via communication interface, a
message “Cumulative+Reset!” is displayed on the first line of the LCD.
Billing period can be manually ended only once per calendar month. If user attempts to end billing
period second time per calendar month, a message “Blocked” is displayed on first line of the LCD.
If billing period is ended manually, meter does not ends billing period automatically at the end of that
calendar month.
