Testo 770-1 is suited for current measurement in switching cabinets. One of the two pincer arms can be fully retracted into the instrument. This unique mechanism means that cables in tight switching cabinets can be easily grabbed. The automatic measurement parameter detection also enables reliable work. Testo 770-1 detect direct and alternating current and select other parameters such as resistance, continuity, diode and capacitance automatically.

Testo 770-1 TRMS clamp meter, batteries and 1 set of measuring cables.

Measure current and voltage in switching cabinets with this high-performance clamp meter from Testo. It has an automatic parameter detection feature that makes it easy to measure values without the need to change the meter settings. Thanks to its two pincer arms, one of which can be fully retracted into the instrument, you can easily grab cables in tight spaces. The meter has a liquid-crystal display (LCD) screen for measurement results that are easy to read.

• Light weight of 302g for ease of handling
• Battery-powered for portable use without the need for an external power supply
• Wide operating temperature range of -10°C to +50°C for use in demanding conditions
• Wide current measuring range of 0.1A to 400A for use in a variety of applications

• Distribution boards
• Machine power panels

The major difference between a clamp meter and a multimeter is that a clamp meter can measure high currents, while a multimeter is more suitable for smaller, more precise measurements.
