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.
• 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 unit up to date.
• Polarity swap: automatic polarity re-versal 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.
• 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.
