Key features

• LED Pass/Fail indicators: two LED indicators 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 real-time.
• 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 MΩ.
• Trip Lock function: Zs (RCD) function performs a loop impedance test without tripping the RCD.
• Multi-system 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.
• BT connectivity: it enables BT communication with Android tablets and smart phones via built-in BT.
• PC SW Eurolink PRO included in the standard set enables downloading of test results and parameters and creation of test reports.
