DISPLAY UNIT

CM7291

Multi-functional Display Unit to Use Right on the Field or
Output to Advanced Recorder or Logger

Hioki clamp on meters are best-in-class measuring devices incorporating Hioki’s expertise in current sensing technology. The CM7291 is the wireless receiving/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.
คุณลักษณะเฉพาะ
  • Send measured values to a smartphone or tablet using Bluetooth® wireless technology
  • Use the GENNECT Cross dedicated app to display and review measured values and waveforms in real time
  • Power supply and signal output for Current Sensor CT7000 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

Model No. (Order Code)

CM7291 For the CT7000 series, with built-in Bluetooth(R) wireless technology

Note: CM7290, CM7291 cannot be used alone. Use with CT7000 series. When used in combination with the CT7000 sensor series, the frequency band for current display and waveform output is narrower than the sensor band.

Data can be downloaded to tablets and smartphones using Hioki’s dedicated apps available from the Google Play or App Store. (CM7291) Search for “HIOKI” and download the “GENNECT Cross” app.

Connect to Recorders, Data loggers, and Oscilloscopes

By connecting an AC/DC current sensor to the Display Unit CM7291, and then the system to a data logger or Memory HiCorder, you can output:

  • A DC or AC (up to 5 kHz/10 kHz) current waveform as-is (using WAVE mode for waveform output)
  • An analog signal generated by converting the input waveform to a series of RMS values (using RMS mode for RMS output)
  • An analog signal generated by detecting the current waveform’s peak value (using PEAK mode for peak output
  • An analog waveform generated by detecting the frequency of the current waveform (using FREQ mode for frequency output)

Basic specifications (Accuracy guaranteed for 1 year, Post-adjustment accuracy guaranteed for 1 year)


* Waterproof characteristics intended to maintain measurement function; measuring energized parts while instrument is wet will increase risk of electric shock.
