Time aging: all the products have been time-aged, so that it can stably work in a long-term to reduce the impact of external environment on the meter, offering users a satisfactory product.

Note:

1. Should be used in the temperature range: -25℃~55℃, humidity: ≤80%, to prevent undesirable phenomena caused by temperature changes.

2. Take care of vibration and shock.

3. Do not use it in places with dust, gas and chemicals harmful for electrical products.

4. If the abnormal voltage is caused by the magnetic field, high frequency devices, high voltage spark, lightning and etc, please use the external power line filter or non-linear resistors to interfere and absorb the circuit.

5. The signal input line should be as short as possible, and protective shielding wire should be used in places where there may be interfering signals. It is recommended to use twister pair in general conditions.
