AAC-ENM-I Ground Master Equipment Ground Monitor continually monitors the grounding status of equipment. It provides independent ground monitoring of one tool. Monitoring of ground connection is done according to the ANSI/ESDA S.20.20 standard. Specific limits are set to the customer requirements. If no requirements are specified, default ground impedance is set at the factory to 500 ohms.
The AAC-ENM-I Ground Master Equipment Ground Monitor provides indication and alarm of the status of the ground and local alarms.
1.24 hours continuous monitoring of ground monitoring function instrument, LCD can instantly display the current grounding resistance.
2. Automatic alarm function, real-time monitoring and alarm of the grounding system.
3. The grounding system can monitor the resistance value (0-500Ω), and when the loop resistance of the local line is higher than the set value, it will immediately sound and light alarm.
4. The audible and visual alarm is performed when the grounding system is disconnected, which effectively improves the reliability of the grounding system and is suitable for workplaces with high grounding resistance requirements.
5. Easy to use, no need for additional auxiliary grounding facilities.
6. Can overcome the blind spot of grounding measurement, completely measure the true grounding impedance on the ground and under the ground, to avoid electrostatic damage and personnel electric shock.

1.Tool LEDs: Illuminates green when its respective tool is within the impedance test limits. Blinks red when its respective tool exceeds the .Illuminates solid red and audible alarm sounds when its respective tool exceeds the impedence test limit.
2.LCD: Real-time display of the current grounding resistance. “OL Ω” means loop resistance of the local line is higher than the set value.
Mount the Ground Master Equipment Ground Monitor on a wall or on a side of equipment where it’s stable placement and access to all connections is ensured，the length of wires to the monitored equipment is minimized.
Connecting Reference Ground：
1.The Ground Master Equipment Ground Monitor must be connected to a proper facility ground using its GND connection. This ground will serve as a reference. No monitoring is possible without this connection.
Make sure that this reference ground is a true ground and is properly connected to both facility (power) ground and to ESD ground, should these be separate at your factory.
2.Crimp an 18 AWG (1 mm diameter) wire to the supplied ring terminal and connect it to the GND terminal of the unit. Connect the other end of this wire to the proper facility ground. Minimize the length of this wire since the impedance of this wire will be a significant factor in measuring ground impedance of all connections. Do not coil the extra length of this wire.
Warning light wiring:
Connect the alarm light leads to the alarm wiring jacks on the back of the monitoring host according to the positive and negative poles (the red wire is positive and the black wire is negative).
Monitoring resistance setting:
the upper button is the increase button, and the lower button is the decrease button. After setting the required parameters, the monitor will automatically recognize and save.
