               Straight tip: 2.11kg

Temp Range: -25℃~+60℃

Humidity Range: Relative humidity,not more than 85% RH


Features:

1. High precision,high sensitivity,high reliability,long life,low power   consumption , lifetime withoutverification.

2.LCD displays total used electricity,remaining balance.Remaining balance or   Remaining balance with newly purchased electrcity not more than 999999.99 kWh. Maximum total used electrcity not more than 999999.99,when it exceeds the maximum,it will counts from ziro.

3. Warning:When remiaing balance is less than a setting amount,the watthour meter will power off to remind you to perchase electrcity.

4. Overload: When the user's actual used power exceeds a setting power value,the meter will automatically power off and displyas“E3”at the same time.The user needs to insert (sweep) the card inside (on) the watthour meter,then power on.

5.Lack phase:If lack of a phase,the meter will automatically power-off,and displays"E4
".When recoverys the phase,insert(sweep)card to make power on.

6.Write back function:Write back the total consumption,remaining balance,over load times,and other information to the IC Card for the convenience of management.

7.Data protecton:Apply overall solid integrate circuit technology for data protection,so no battery is needed,and data can be saved for 10 years after the electricity is cut off.
