Power connection
(1) Power supply voltage range: 220V AC ± 10%, or 110V AC ± 10%.
(2) Power supply frequency range: 45-65Hz.
(3) Phase line L, zero line N, and ground line E of power input shall be the same as those of the power plug of this instrument.
(4) The instrument has been carefully designed to reduce the clutter interference caused by the input at the AC power supply terminal. However, it shall be used in a low noise environment. If such is not the case, please install the power supply filter.
WARNING: In order to prevent leakage from causing damage to the instrument or person, the user must ensure that the ground line of the power supply is reliably connected to the earth.
