Metrel MI3290 GF Earth Analyser

The Metrel MI3290 GF Earth Analyser is capable of performing 2-, 3-, and 4-pole earth testing and can use the Wenner and Schlumberger methods with four-pole testing. Furthermore, it can carry out measurements such as step/touch voltage measurements, voltage potential measurement, low impedance 4-point tests, and low resistance tests with a 200mA or 7mA test current. This makes it suitable for testing earthing facilities on transformer stations and in domestic environments.

One of the most notable features of the Metrel MI3290 GF is the wide frequency range. It can test at frequencies between 55Hz and 15kHz using either a single test or by exploiting the whole of the range with the sweep mode. A filter for high frequency noise makes the earth tester highly resistant to interference, thus making readings more accurate.

The 3.4” colour touchscreen on the Metrel MI3290 GF can display earth test readings in both numerical and graphical formats as well as allowing the user to operate the analyser via the intuitive menu system. A set of navigation buttons is also available. Readings are saved to the large 1GB internal memory.

Once saved to the Metrel MI3290 GF’s memory, supplied Metrel ES software can be used to analyse and report on earth test results. It also facilitates data transfer via a USB cable or a wireless Bluetooth connection.

The Metrel MI3290 GF works from both the supplied NimH batteries or from the mains so it is very versatile. An IP54 rating when open and an IP65 rating when closed certifies that the earth tester is suited to use on industrial sites. It is supplied with accessories including test leads, test probes, crocodile clips, a G clamp, a voltmeter, a Kelvin clamp, a step voltage test plate, and a carry case.
