The human body static discharge alarm is a device suitable for the discharge of human body static electricity in flammable, explosive, and anti-static places
Instruments and meters. Its characteristic lies in the design of a reasonable human body electrostatic discharge resistor, which effectively controls human body electrostatic discharge and prolongs human life
The static discharge time of the body reduces the instantaneous energy released by human static electricity, which can ensure the safe discharge of human static electricity. Simultaneously capable of detecting people
Whether the static electricity discharge alarm is properly grounded, whether the contact between the human body and the explosion-proof touch ball is reliable, and whether the static voltage display shows the person
The static voltage value carried by the body and the sound and light alarm indicate whether the static voltage value exceeds the set alarm voltage

Product Usage
dormant state
When there is no contact between the human body and the explosion-proof touch ball, the human body static discharge alarm is in a sleep state, and the static voltage display is displayed
Not displaying, buzzer not sounding
alarm status
When the human body comes into reliable contact with the explosion-proof touch ball, the human body static discharge alarm senses the human body and detects the presence of a human body strap
When the electricity reaches the alarm voltage, it enters the alarm state, the static voltage display shows the static voltage value, the buzzer alarms, and the red light flashes.
Static electricity is being released, please do not leave!
normal state
When the human body comes into reliable contact with the explosion-proof touch ball, the human body static discharge alarm senses the human body and detects the presence of a human body strap
When the electricity is less than the alarm voltage, it enters the normal state, the static voltage display shows the static voltage value, the buzzer does not sound an alarm, and the green light flashes. Hands can leave the touch ball and enter sleep mode after 5 seconds. After static discharge is completed, one can enter hazardous areas for work.
Grounding alarm status
When the grounding wire is disconnected, the human body static discharge alarm is in the grounding alarm state and does not detect static voltage. The static voltage is displayed
The indicator does not display, the buzzer sounds an alarm, and the yellow light flashes. After a grounding alarm lasts for 1 minute, it enters sleep mode. When the explosion-proof touch ball is touched again, the system wakes up and continues to check if the grounding is normal
