Metrel MI3288 Earth Insulation Tester
The Metrel MI3288 Earth Insulation Tester is a portable, rugged (IP54 and 300V CAT III), battery-operated earth tester. It supports an eclectic selection of earth resistance measuring methods including four-wire earth resistance; one-clamp earth resistance; two-clamp earth resistance; and four-wire specific earth resistance. In addition to earth resistance and specific earth resistance, the Metrel MI3288 can ascertain earth potential, step and touch voltages, true-RMS current, insulation resistance, and continuity of protection conductors of various energetic and non-energetic objects. This universal tester can also determine the breakdown voltage of overvoltage protection devices. Measurements are indicated on the 4.3-inch LCD touchscreen and can be saved to the Metrel MI3288 for download to a PC using the Metrel ES Manager Software. This PC application can also be used to evaluate data and create reports.
Measuring Functions
Offering programmable Auto Sequences and high and low limits, as well as single or automated measurements, the Metrel MI3288 delivers the following tests:
- Earth resistance 2/3/4-pole
- Selective earth resistance (1x clamp)
- Specific earth resistance Ro Wenner and Schlumberger method
- Earth resistance with 2x iron clamps
- Earth potential
- Step and touch voltage measurement with external P/S probe
- Insulation resistance up to 100 GΩ with DC voltage from 50V to 2500V; a guard terminal; automatic discharge; and additional filtering options (Off, 5s, 10s, 30s, 60s)
- PI and DAR calculation
- Dielectric discharge (DD) ratio
- 4-wire/ 2-wire 200mA DC resistance measurement
- 2-wire continuity 7mA measurement
- Resistance measurement using four-wire Kelvin method
- Resistance (µΩ) with single, continuous and inductive mode of operation with selectable current: 10 mA, 100 mA, 1A and 2A (bidirectional)
- Capacitive measurements
- 2.5kV varistor test

When conducting earth measurements, the Metrel MI3288 provides a multi-frequency test signal on the output voltage (20/40 V AC). This ensures the best noise immunity (55Hz is also supported).
Resilient, Ergonomic Design
Data is indicated on the Metrel MI3288 Earth Insulation Tester’s 4.3-inch, colour, touchscreen LCD. Built-in Bluetooth connectivity facilitates communication with a PC, Android tablets and smartphones. Metrel’s ES Manager PC Software enables pre- and post-processing of test structures; results download; tree-view, table-view and graphical-view of data; as well as storing and printing of measurements.
Practically, the Metrel MI3288 is powered by rechargeable Li-Ion batteries and includes an integrated charger. Additionally, it offers a high degree of protection. The Metrel MI3288 Earth Insulation Tester is IP54-rated and is certified 600V CAT II, 300V CAT III (at 4000m above sea level).
The Metrel MI3288 Earth Insulation Tester is a durable, dependable earth tester with an eclectic testing capability.
