Fluke Multifunction Tester, 1000V Insulation Test Voltage, 500V Maximum Voltage Measurement - 1664FC DE FTT KIT

This multifunction tester is a portable electrical installation instrument designed for verifying fixed wiring safety in domestic, commercial and industrial environments. It combines automated test sequencing with wireless data transfer capability and a safety pretest that halts insulation measurements if connected appliances are detected, reducing the risk of damage to peripheral equipment.

Features & Benefits

• Auto Test sequence reduces test time by up to 40%
• Insulation PreTest stops insulation when appliances detected
• Insulation test up to 1000V for comprehensive resistance checks
• Continuity testing at 1mA with up to 2000 Ω measurement range
• Loop impedance measurements phase to NEUTRAL and phase to earth
• RCD ramp and automatic RCD test including Type S and Type G

Applications

• Suitable for installation verification to IEC 60364 requirements
• Ideal for periodic inspection and certification of fixed wiring
• Used for commissioning new electrical installations in buildings
• Can be used for fault-finding on RCD-protected circuits
• Suitable for contractors needing wireless result sharing on-site

What power source and portability features does it use?

It runs from six AA batteries and includes a hard carrying case and shoulder strap for field mobility.

How are measurement records transferred and stored?

Measurements can be sent wirelessly to a smartphone via a mobile app and saved to Cloud storage for later retrieval and certificate generation.

What safety and overvoltage categories apply to measurements?

The instrument meets CAT III 500V and CAT IV 300V overvoltage classifications for safe use on distribution and supply-side circuits.

Can it perform earth resistance measurements and what output does it use?

Yes

earth resistance ranges include 200 Ω and 2000 Ω using a 128Hz test frequency with a 25V output.
