1.Technical parameters
1.1.Main technical parameters
1.1.1.Working voltage
1)Rated voltage Un:220V
2)Scope of working voltage: 75%Un~120%Un
Within the scope of the work voltage meter works normally
3)Limitation of scope of working voltage: 70%Un~130%Un 
Within the limit of voltage scope, the meter won’t be damaged, and when meter can display normally, it will guarantee the measurement, but can't ensure the measuring accuracy level. After the working voltage returns back to normal, the measuring accuracy level will remains the same.
1.1.2.Current parameter
1)Max current Imax                                       60A
2)Starting current (0.4%Ib)                            20mA
3)Scope of measuring current                       20mA ~ 60A
4)Commonly used current specifications       5(60)A
1.1.3.Frequency parameter
1)Rated frequency fn                                     50Hz
2)Frequency range                                 95% fn~105% fn
1.1.4.Meter power consumption
3)Power consumption of voltage circuit                            ≤0.8W  4VA
4)Power consumption of current circuit                            ≤4VA
1.1.5.Active energy measuring accuracy
The active energy measuring accuracy complies with IEC62053-21   class 1
Single phase meter--- active class 1 percentage of error limits
Form 1:Active class 1 percentage of error limits
1.1.6.Display mode
●Display type                     Wide temperature type LCD 
● Number of digits display        8 digits, 8 integers and 0 decimal
1.1.7. Pulse constant 
Active: 1000imp/kWh
1.1.8. Active calibrating output 
Single-phase active energy meter test pulse lights (LED, located on the meter panel) to ensure the accuracy of the electric energy measure when testing for different current test point, the number of pulses of the test should be progressive increase with the increase of the testing current, and reasonable selection within 1-8 pulses.

4.Notes on Installation
1)Before wiring, please review the wiring instructions on the housing, make sure the cable out of phase, neutral (ground) line and wiring diagram on the housing are corresponding with each other. The best way is to introduce it with copper or copper fittings.
2)if the practical power cable is an old cable, you should cut off the end of the cable, ensure that the new thread exposed about 15mm long to prepare wiring; if the cable diameter is between 3mm to 6.5 mm, direct connection to the terminal holes inside, ensure securely fastened; if the cable diameter is less than 3 mm, then you should use a suitably sized copper or aluminum bushing to clamp the end of cable, which will prevent bad wiring and causing the terminal burned.
3)When wiring, first loosen the screws on each post, and then inserted the phase line into the end of wiring hole, then insert the neutral line into the end of terminal wiring hole, fully tighten the screws on each terminal. Similarly insert the outlet phase line into the end of wiring hole, fully tighten the screws on each post. Tightly secured to ensure good contact.
4)Electrify meter and check the operation status of the meter. If the meter is working properly, record the reading. If the meter does not work, double-check the installation and wiring as well as the operating voltage.
5)During the installation process, the operator should handle it gently and carefully, avoid dropping and impact.
6)During the meter installation procedure, the operator should pay attention to electrical safety and prevent accidents.
