Earth resistance (3-wire method).

OTHER FEATURES

LED Pass/Fail indicators: two LED in-dicators for PASS / FAIL evaluation of test results are placed on both sides of the LCD
Help screens: instrument comes complete with built-in help screens for referencing on site.
Earth resistance measurement: instrument performs 3-wire earth resistance testing with two additional rods.
Built-in fuse tables: this unique feature allows automatic evaluation of the line / loop impedance compared to the regulations.
Online voltage monitoring: monitors all 3 voltages in realtime.
Upgradeable: if changes occur to the regulations, upgrades can be made to the firmware to keep the instrument up to date.
Polarity swap: automatic polarity reversal on continuity test.
Insulation range: wide range of insulation test voltages from 50 V to 1000 V, reading up to 1000 M?.
Trip Lock function: Zs (RCD) function performs a loop impedance test without tripping the RCD.
Multisystem testing: tests on single and multiphase TT and TN systems.
Built-in charger & rechargeable batteries: unit has a built-in charging circuit and comes complete with a set of rechargeable NiMH batteries.
RCD auto: automated RCD testing procedure significantly reduces test time. B type RCD testing is supported.
PC SW EuroLink PRO included in the the standard set enables downloading of test results and parameters and creation of test reports.
