Explanation on wiring methods, magnetic retention relays, and automatic recovery of undervoltage and overvoltage
When this meter is first powered on, the built-in magnetic retention relay needs to be reset. During this period, it will be turned on for more than ten seconds and maintain the output (delay protection). Only when the startup is completed and the measurement interface is reached, can the over limit enable (such as overvoltage, undervoltage, overcurrent, and overpower protection functions take effect) and the normal working mode of the measurement data be achieved,
This meter can freely set the recovery time for undervoltage and overvoltage (1-99 minutes). When the voltage is restored, normal power supply will be restored within the time you set!
(In view of this, please strictly follow the wiring diagram in this table to connect the air switch at the output end, and wait for the meter to start before turning on your device's air switch.)
