AC CLAMP METER CM4141
Innovative Current Sensor Design
Easily Get Into Tight Spaces
Hioki clamp on meters are best-in-class measuring devices incorporating Hioki’s expertise in current sensing technology. The CM4141 is a 2000 A AC True RMS clamp meter that features a uniquely designed slim jaw that lets you easily get into the narrow gaps between cables in crowded electrical distribution boxes without fear of damaging the cables or the clamp meter. The broad -25°C to 65°C operating temperature range and IP50 dustproof and waterproof enclosure to enable professionals to work quickly in crowded electrical distribution panels. The high current measurement capability makes it especially useful for industrial applications.

- *1:Your instrument can be used to measure voltages in excess of 1000V DC if and only if both of the following conditions are satisfied:
- 1. The circuit under measurement is isolated from the commercial power grid.
- 2. The circuit under measurement is isolated from ground.
- e.g.: When measuring the no-load voltage of an ungrounded PV panel
- Do not use the instrument with circuits whose terminal-to-ground voltage exceeds 1000V. Doing so may result in electric shock.
