Gossen-Metrawatt Electrical Installation Tester, 1000V Insulation Test Voltage, 300V Safety Category Voltage - M516M

This electrical installation tester assists qualified technicians in verifying protective devices, insulation integrity and earth continuity during installation and maintenance. It operates across a wide supply range and supports automatic and manual RCD testing, loop impedance evaluation and earth resistance measurement to assess circuit safety under site conditions.

Features and Benefits:

• *Made in Germany
• 1000V Insulation Test Voltage enables high-voltage dielectric checks
• 0-200Ω Continuity range provides precise conductor verification
• High/low current loop impedance supports both fault simulation methods
• Automatic RCD ramp test delivers step-response assessment for trip curves
• Lithium-ion battery operation with 85-264V supply offers flexible power

Applications

• Suitable for validating RCD performance in industrial installations
• Used for measuring earth resistance on distribution boards
• Can be used for loop impedance testing in CAT IV environments
• Used with portable test rigs for continuity and insulation checks

What environmental conditions can it operate within?

It functions between 5°C and 50°C ambient temperatures and has an IP40 ingress rating.

How does it communicate recorded results?

Data can be downloaded via an RS232 Interface for logging and analysis.

What safety classifications apply during live testing?

It is rated for 300V and meets safety categories CAT III and CAT IV.

What RCD types and modes are supported?

It performs AC, Type B, B+ and F tests and includes non-tripping and ramp test modes.

What power arrangements does it accept for prolonged use?

It runs from three lithium-ion batteries and accepts 85V to 264V ac at 16.7Hz to 400Hz mains.
