Key features

• Autosequences: Testing of electrical installation safety with AUTO SEQUENCE ® is up to 5 times faster compared to traditional installation tester.
• All-in-one insulation: insulation tests between L-N, L-PE and N-PE can be performed simultaneously in less than 10 seconds.
• Medical site testing: measurement of First fault leakage current (ISFL) and insulation monitoring device (IMD) checking.
• Structure building: a structure of the installation (up to 10 levels) can be built either using the software (which can then be sent to the instrument) or directly on the tester so that test results are always saved on the correct circuit.
• Barcode reading support: reading of data from barcode labelled installation structure elements for fast naming of memory locations on the field.
• Fuse location: function enables the locating of fuses / wires / faults with the help of the optional A 1191 Fuse locator.
• Earth resistance measurement: Tester can perform 3-wire earth resistance testing, one clamp and two clamps earth resistance and specific earth resistance measurement.
• Downloadable: downloads via RS232 or USB cable directly to the PC with the help of the software included in the standard set.
• Help screens: instrument comes complete with built-in help screens for referencing on site.
• 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 TT, TN, IT and reduced low voltage systems.
• Wide frequency range: 14 ... 500 Hz.
• 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 optional BT dongle.
• PC SW EuroLink PRO included in the standard set enables downloading of test results and parameters and creation of test reports.
