4. Event Log
- Permanent record the time when reset happened, and also the data on
that time.
- Recording total times for programming, the time for last 10
programming and also operation code and data identification for
programming.
- Recording total times for timing (not including time broadcasting),
the time for last 10 timing and also operation code.
- Recording total times for power down, the time for last 10 power
down and power on.
- Recording the last 10 times for switch out and on by remote
control, and also the time for switch out/on, power and etc.
- Recording the total times for opening meter cover, the time for
last 10 opening happened and finished.
5. Display
- The following information would be displayed in meter:
- The unit for power is kWh, and 8 digital display, including 2
decimals.
- LCD backlight wake up methods including switch wake up, infrared
wake up(any infrared can work) and etc. In normal use, the life
time for LCD won’t be less than 10 years
- When power off, the backlight can be woke up by switch; If no
operation after waking up, LCD would close automatically after a
cycle; If operation exist, LCD would close automatically in 30
seconds after operation.
- Indicator: --Pulse Red, it is off in normal condition, and would be
flash when measuring active power
6. Alarm
When the following faults or alarm appear, LCD would stop on the
certain code and backlight keep on.
7. Freezing
8. Timinh
