3. Prevent from violent vibration,shock and incursion of heavy dust.
4. storage long times at -10~70ºC,under 70%RH environment.
5. Install power switches and circuit breaker for power safety.
6. When meter power supply has noises,particularly when instant inductive
voltage caused by relay or contact devices switch ON and OFF result in
serious interference,must configure filter , rheostat or noises absorber.
