Botron B920724 – Dual Wire Monitor for Two Operators (Includes B920733 Remote)

• Dual wire monitor
• Designed for dual-wire wrist strap systems
• Independently measures the resistance of both sides of the band and ground
• LED pass/fail indicators and audible alarm
• Supports 2 operators via 3.5mm dual wire ESD wrist strap connections

The Botron B920724 resistive dual wire monitor is designed for use with dual wire wrist strap systems. It independently measures the resistance of both sides of the band for one operator and ground and includes LED pass/fail indicators, as well as an audible alarm.

Theory of operation

The B920724 dual wire workstation monitor is designed to monitor the operation of the wrist strap grounding systems of two operators. To accomplish this, it uses a DC current source to measure a loop electrical resistance. The system uses a dual-wire wristband and ground cord that contain two independent elements. The B920724 monitor employs two selectable test voltages (9 and 16 volts) and resistance limits(10 Megohms and 35 Megohms) It also monitors the grounding of up to two work surfaces.
