Gossen-Metrawatt Electrical Installation Tester, 50°C Maximum Operating Temperature, 5°C Minimum Operating Temperature - M516L

This electrical installation tester is a portable analyser designed for verifying protective devices, insulation and continuity on-site. It operates across a wide ambient range and supports mains or battery operation for field testing. Built to Interface with external equipment, it facilitates data transfer and recording during routine inspections and commissioning tasks.

Features and Benefits:

• *Made in Germany
• 1000V insulation test voltage enables high-voltage dielectric checks
• Loop impedance high/low current measurement improves fault localisation
• Continuity testing up to 200Ω assists conductor integrity verification
• Automatic RCD ramp test provides progressive trip characteristic assessment
• RS232 Interface allows straightforward data extraction for reporting

Applications

• Suitable for validating RCD performance including Type B F AC
• Ideal for earth resistance measurement tasks on distribution boards
• Used for portable electrical safety analysis in workshops
• Can be used for loop impedance verification under CAT III 600V conditions
• Used for insulation testing during installation and maintenance

What power sources are available for field use?

It accepts 85V to 264V mains input and operates from three lithium‑ion batteries.

Which safety categories and voltages does it support?

The unit meets CAT III 600V and CAT IV 300V safety classifications for installation work.

How is non-tripping testing handled?

Non-tripping mode is not provided

all RCD tests utilise tripping measurements or ramp routines.

What environmental protection does it offer for site work?

The enclosure has an IP40 rating for protection against solid objects in controlled environments.

What connectivity options enable test data management?

Data can be downloaded via the RS232 Interface for post-test analysis.
