- Previous month consumption in KWH.
- Consumption of last previous 12 months.
- Total consumption from installation time.
- Meter serial number.
- Date (Day – Month – Year) and current time (24 hours).
- Type of use according to electricity company’s requirement.
- Last fraud and tamper case will be shown (in date and time).
- 2 pages can be programmed according to electricity companies
Display screen will show the following messages.
- (Please recharge) in case of low credit.
- (Battery low level) in case of the battery is low.
- (Load excessive) in case of the load excessive than the programmed current to the meter (disconnection limit) for 5 minutes. If the load excessive repeated 3 times, the magnetic rely will trip.
- (High Volt) in case of overvoltage.
- (Low volt) in case of undervoltage.
