Measuring Functions
- Earth spike testing: unit performs both 2 and 3 wire earth spike testing.
- Medical site testing: ISFL– First fault leakage current, IMD – insulation monitoring device check.
- Downloadable: downloads via RS232 or USB cable directly to the PC via the software included with the unit.
- Help screens: unit comes complete with in-built help screens for referencing on site.
- Automatic loop evaluation: built-in loop impedance tables allow automatic evaluation of the loop resistance compared to the regulations.
- Tip commander: unit comes complete with a tip-commander to simplify continuity and insulation testing.
- Online voltage monitoring: monitors all 3 voltages in real-time.
- Upgradeable: if changes occur to the regulations, software changes can be made to the firmware to keep the unit up to date.
- Polarity swap: automatic polarity reversal on continuity test.
- Insulation range: wide range of insulation test voltages from 100 V to 1000 V, reading up to 1000 MΩ.
- TripLock function: Zs (RCD) function performs a loop test without tripping the RCD/RCBO.
- Multi-system testing: tests on TT, TN, IT and 110 V systems.
- Built-in charger & rechargeable batteries: Unit has an inbuilt charging circuit and comes complete with a set of rechargeable NiMH batteries.
- RCD auto: Automated RCD testing reduces circuit test time.
