High power motors, generators, transformers, ovens, presses, etc. can all cause interference with magnetic or electric fields. Temperature changes can also cause peak spectral drift, leading to incorrect test data. In environments with excessive humidity, long-term operation of instruments may result in serious consequences such as abnormal voltage discharge and breakdown of phototubes. It is recommended that customers stay as far away from interference sources as possible, maintain a constant temperature (between 15-25 ℃) and a balanced humidity (relative humidity less than 70%), while also ensuring a voltage of 220V ± 5V and equipped with a regulated power supply.
