--Alarm Red, it is off in normal condition, and would be on when alarming
--Trip Yellow, it is off in normal condition, and would be on when load switch disconnect.
When the following faults or alarm appear, LCD would stop on the certain code and backlight keep on.
Time Freezing: Freezing meter data according to the promissory time and interval; It can keep at least 12 times for each frozen fraction.
Instantaneous Freezing: Under improper condition, freezing current date time, all power and important measurement data; It keeps the data for last 3 times.
Appoint Freezing: In any case of older/new tariff, step tariff changeover and other situation which is necessary, the meter would freeze power and other important data on the changeover time, It keeps the data for last 2 times
Day Freezing: Store power on 0.00am for each day, total for 2 month
On Hour Freezing: Store active power for hour or half an hour, total for 96 data
Build in clock circuit with temperature compensation function, the calendar, timing, leap year can be changed over automatically. The output frequency for inner clock terminal is 1Hz. Between -25℃ to +60℃, clock accuracy is no more than ±1 s/d; Under reference temperature 23℃, clock accuracy is no more than ±0.5 s/d.
The accepted time broadcasting is no more than 5 min. No need to match with programming switch and communication password when time broadcasting. It can be set according to the inquire, and it avoid from handling in 5 min at the time when freezing or data storing.
Meter has function for LED pulse and electrical pulse output which comes direct ratio with measuring energy. Optical test output device should comply gb/t17215.211-2006, electricity test output device should comply GB/T15284-2002. It has signal output terminal for clock, and the output frequency is 1Hz
External load switch, there is a group of switch signal for meter output. Volume of switch point is AC 220V/2A. Under normal condition, switch signal for output should keep switch on of load switch, allow for power on; When reach certain condition, switch signal for output should drive operation for external load switch, power off.
＊ Use only isolated tools.
＊ Do not connect the meter to a 3 phase - 415V AC - network.
＊ Place the meter only in dry surroundings.
＊ Make sure the used wires are suitable for the max current the meter can measure.
＊ Make sure the AC wires are installed correctly before activating the current/voltage.
＊ Do not touch the meter connecting clamps directly with your bare hands, with metal, blank wire or other material as you will have the chance of an electricity shock and a possible chance for health damage.
＊ Make sure the protection cover is placed after installation and has been sealed.
＊ Installation, maintenance and repair should only be done by a certified electrician.
＊ Never break the seals or open the front cover as this might influence the functionality of the meter.
＊ Do not through, drop, kick or other physical violence to the meter as there are high precision components inside that will break or make the meter measure inaccurate.
＊ Do not mount the meter in area's with harm gas, dust, mildew or insects or on unstable surfaces.
