ES3000 earth resistance tester. Features
- Earth resistance, earth voltage, low resistance measurement
- Earth resistance measurement: 0.00 Ω-3000.0 Ω
- Measurement method: 3- and 2-wire measurement
- Earth voltage measurement: 0.00 V-100 V
- USB interface, + software
- Store 5000 data groups
The microprocessor-controlled ES3000 digital earth resistance tester with a large, backlit LCD can perform accurate, fast, simple, stable and reliable measurements using the two- and three-wire method.
The ES3000 digital earth resistance tester automatically detects the state of each connection, as well as the disturbance voltage and its frequency, and also measures the resistance value of the auxiliary probes, and displays it on the same screen together with the value of the measured earth resistance. The measurement range of ground resistance is 0.01Ω ~ 3000Ω, the range of ground voltage is 0~100V. 500 data groups can be stored simultaneously in the device's built-in memory. The stored data can be recalled on to the display and downloaded to a PC via the USB port. Special functions are adjustable limit values and alarms
