Gossen-Metrawatt Multimeter, 1000V Maximum AC Voltage, 1A Maximum DC Current - M274S

This multimeter is a handheld digital instrument designed for precision electrical measurement across a range of signals. It operates from battery power or USB and delivers accurate readings for voltage, current, resistance, frequency and temperature while supporting industrial safety categories. The meter incorporates true RMS measurement and accepts an inductance Coil adaptor for expanded component testing.

Features and Benefits:

• *Made in Germany - including DAkkS calibration certificate and 3-year warranty (extendable to 5 years)
• 0.15% DC voltage accuracy for precise measurement
• True RMS capability for accurate AC waveform readings
• 300kHz maximum frequency for high-frequency signal analysis
• Lithium‑polymer battery with 20 h runtime for extended field use
• 1000 V safety rating for CAT III and CAT IV environments

Applications

• Suitable for fault finding on industrial power systems
• Ideal for testing in distribution boards and switchgear
• Used for motor start investigations including inrush current
• Can be used with Coil adaptor for inductance testing
• Used for calibration checks with supplied DAkkS certificate

What power sources does it accept for operation?

It runs from an internal 3.7 V lithium‑polymer battery and can be powered via USB.

What measurement ranges are available for resistance and inductance?

Resistance spans up to 30 000 kΩ with 0.10 Ω resolution and inductance via a Coil adaptor covers 10 μH to 5 H depending on the Coil used.

How does the instrument handle current measurement?

It measures AC and DC currents up to 1 A with 0.01 μA resolution for detailed low‑current readings.

What environmental temperatures can it operate within?

It is specified to operate between -10 °C and 50 °C.

What approvals and documentation accompany the device?

It is CE‑marked and supplied with a DAkkS calibration certificate.
