Hioki CT7736 AC/DC Auto-Zero Current Sensor

Hioki clamp on meters are best-in-class measuring devices incorporating Hioki’s expertise in current sensing technology. The CT7736 is a 600 A AC/DC Current Sensor that pairs with the detachable Display Unit CM7290 or CM7291 for convenient field testing, while delivering an extended temperature range and auto-zero adjustment to minimize drift due to wide temperature changes that occur during long-term testing. 

Further extend the functionality of this system by connecting the Display Unit with a Hioki memory recorder or logger. 

CAT IV 600 V 

Key Features

  • Accurately measure and record even when the temperature changes
  • Ideal for site inspections by using detachable Display Unit
  • Four output formats to output data to loggers or other devices (via Display Unit): WAVE, RMS, PEAK, Hz

Connect to Recorders, Data loggers, and Oscilloscopes

Must be paired with the Display Unit CM7290 or CM7291 to operate as a standalone unit. Add an output cord to deliver signals to a data logger or Memory HiCorder for the following types of 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)

Broad temperature range

A wide operating temperature range of -25°C to 65°C (-13°F to 149°F)lets you use the sensor even in sub-freezing temperatures and on hot summer days.

Take measurements without shifts in the zero-point, even during extended recording with temperature variations

Because temperature variations cause the zero-point to shift when using a conventional DC current sensor to measure DC current, it is necessary to perform zero-adjustment periodically when recording data over an extended period of time with such a sensor. This shortcoming is caused by the effects of the Hall element that conventional DC current sensors use to to detect current. Hioki’s new auto-zero current sensors incorporate a new switching-based offset cancellation circuit developed to address this problem. The new design minimizes zero-point shift, making it possible to record DC current values over an extended period of time without the need for periodic zero-adjustment.
