Description

DISPLAY UNIT
CM7290

Display And Output Unit For The CT7600 And CT7700 Series AC/DC Current Sensors

Hioki clamp on meters are best-in-class measuring devices incorporating Hioki’s expertise in current sensing technology. The CM7290 is the display and output unit for the CT7600 and CT7700 AC/DC Current Sensor series, creating a standalone clamp meter for field use or enabling waveform signals to be output to a Hioki memory recorder or logger for further analysis.

Key Features

• Power supply and signal output for Current Sensor CT7600, CT7700, CT7040 series

• Simultaneous dual display of the measured values, frequency, and output rate

• Four output formats to output data to loggers or other devices (via Display Unit)

• Supports AC adapter, AA alkaline batteries, and external power supply
