In a modern electronic facility, proper grounding is crucial for safe and uninterrupted operation of equipment. Especially when the control environments are critical, any broken or lose ground connections may result in personnel exposure to dangerous voltage, equipment malfunction, and damages to those ESD sensitive components.
The GZ-1980 grounding monitor is a digital precision instrument designed to formulate a network for monitoring of the grounding on industrial equipment with multiple grounding points. Up to eight low resistance grounds can be monitored by one GZ-1980. The high resistance limit can be set through software. The real-time status is displayed on the front panel using bicolor LED’s.
With the built-in network circuitry within each GZ-1980, multiple GZ-1980 units can be easily inter-connected to become a network that can be controlled from a PC-based management program. All the alarm records with detailed data in the monitor network can be logged in a database.

• Wherever ESD and grounding are an Issue
• Many assembly machines consist of several parts which are not always grounded. Their ground connections may also be broken during maintenance, modifications, and even in normal use. GZ-1980 can simultaneously monitor the ground connection of every single part of the entire tool to assure its compliance with the standards and its uninterrupted operation. GZ-1980 provides external relay for equipment to stop in case of ground failures.
