Description

Hioki clamp meters are best-in-class measuring devices incorporating Hioki’s expertise in current sensing technology. The CM4373 is a 2000A True RMS clamp meter that features stronger jaws, broader -25℃ to 65℃ operating temperature range and IP54 dustproof and waterproof enclosure to enable professionals to work quickly in tough situations including the development, repair, and maintenance of equipment and devices such as electric vehicles. Additionally, the high-voltage DC measurement capability of up to 1700 V is ideal for the clamp maintenance inspections of electrical and solar power equipment.

CAT IV 600 V, CAT III 1000 V

How to Use the Hioki CM4370 Series Clamp Meters
Auto Hold Function:

The Auto Hold feature is perfect in situations where the display is hard to read because the clamped wires are in hard to reach locations. With Auto Hold, measured results automatically freeze on the display until the next measurement starts, making testing and record taking a snap.

Simultaneous Display of DC Current and DC Voltage:

The CM4370 Series can measure both DC current and DC voltage with a single device at the same time, making it ideal for automotive battery testing and inspection and maintenance of solar panels.

 

 

How to Use the Hioki CM4370 Series Clamp Meters
Inrush Measurement Function:

Accurately measure the startup or inrush current of motors and equipment. The CM4370 series is engineered to detect the full startup current period and then identify the RMS waveform as well as the highest waveform peak.
