Attentions

1. Wiring should be strictly follow the wiring diagram on the back of the meter.
2. Do not use at the place where exist excessive dust and excessive harmful gases.
3. Long time no use,please charge once every three months,lasting at least 4 hours.
4. Long-term preservation should avoid the direct rays of light,between -10 °C ~ 70°C is suitable for storage.
5. If the meter display nothing,first please check whether the auxiliary power and the voltage are in the setting range.


The following conditions will lead to the device be damage or work abnormal:

1). The auxiliary power supply, voltage, frequency are over-range.
2). Please do not treat the PT signal as well as the auxiliary power supply at the same time Unless the PT have enough power, so that the meter can be ensured to work normally.
3). CT circuit current wiring terminal screws must be tightened, and ensure the inlet / outlet lines are reliable to avoid faults.
4). If checking meter, the calibration instrumentation should be prior a class 0.1 magnitude, so that the accuracy could be ensured.
