Gossen-Metrawatt Ohmmeter, 99.9Ω Maximum Resistance, 0.10Ω Resolution - M630K

This ohmmeter is a portable resistance metre designed for low-resistance measurement in field and bench environments. It performs four-wire measurements to reduce lead influence and operates from standard AA batteries, making it suitable for situations where mains power is unavailable. The unit functions across a controlled temperature span and meets recognised safety standards for electrical test instruments.

Features and Benefits:

• 4-wire measurement for reduced lead error and clearer readings
• 99.9Ω maximum range for low-resistance verification
• 0.10Ω resolution for detecting small resistance differences
• 2% maximum accuracy for consistent comparative testing
• Battery-powered operation for use without mains supply

Applications

• Suitable for verification of bonding and earthing conductors
• Ideal for component lead resistance checks in workshops
• Used for maintenance testing of contact resistance in switchgear
• Can be used for low-resistance traceability during assembly
• Suitable for portable on-site fault-finding tasks

What battery type does it require?

It is powered by standard AA batteries.

What environmental temperatures can it be used within?

It operates between 0 to 40°C.

How heavy is the instrument for portable use?

The device weighs 1.75 kg.

Which safety standards does it conform to?

It complies with DIN EN 61010-1 and IEC 61010-1.
