Description
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
Basic specifications
Accuracy guaranteed: 3 years

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. 
Transfer data wirelessly using Bluetooth(R) to GENNECT Cross mobile app
Pair with the CM7291 Display Unit to send measurement data 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.
