Hioki clamp-on meters are best-in-class measuring devices incorporating Hioki’s expertise in current sensing technology. Use the CM4001 to easily clamp within crowded cables in order to reduce work time and improve safety. With guaranteed accuracy from 0.60 mA to 600.0 A, the CM4001 provides a one-stop solution for a variety of applications. A built-in comparator function also helps you find issues much faster.

Perform everyday maintenance work more safely and easily

• Slim jaws simplify measurements within crowded cables, improve efficiency and reduce work time
• Filter function eliminates unwanted noise to let you measure close to the 50 Hz/60 Hz fundamental frequency
• White backlight, measured value hold, and auto power-off features add convenience
• [AUTO HOLD] function automatically holds the measured value for use in difficult places to see the display

Support for troubleshooting and diagnostics

• The CM4001 retains maximum, minimum, and average [MAX/MIN/ AVG] RMS current values to make it easier to analyze potential problems
• Waveform peak value measurement [PEAK] capture intermittent or transient events
• Inrush current measurement [INRUSH] captures the starting current up to 150 ms from the trigger to help locate equipment startup problems and contributes to a preventive maintenance log for future reference
