Wiring connection guide Installation Pay attention 1, To the power supply: The voltmeter contains DC manostat. The power supply voltage can be random during the voltage range, however, it can be extend the valid voltage, or it will result in inaccurate measurement or instrument damage. When using the switching power supply, switching power supply should be high quality, low -grade switching power supply with spike pulse much higher than the nominal value of voltage can cause instrument damage. 2, Please shield the instrument install anti-jamming circuit if there is strong interference source. 3, Make sure the instruments working environment meet the following requirements: Temperature -10 ~ +55 , Humidity 20 ~ 80% RH (no condensation). 4, Instrument should guard against the strong vibration and shock, otherwise it may result in inaccurate measurements or damage.
