Description
Key Features
- Achieve large current measurement with high accuracy
- 3 channel input
- Automatically recognize and scale simply by connecting the sensor
- High speed sampling of 5 MS/s ensures high-speed phenomena are captured
- High 16-bit A/D resolution
- For Memory HiCorder MR6000, MR6000-01（ver. 2.10 or later), MR8740T (ver. 2.00 or later), and MR8847A （ver. 2.00 or later)
Single solution for 3-phase current measurement
The U8977 delivers a sampling rate of 5 MS/s, frequency characteristics of 2 MHz, 16-bit A/D resolution, and DC accuracy of 0.3% f.s. to facilitate wideband, high-precision current measurement using Hioki current sensors.
Automatic configuration of sensor scaling values
When you connect a current sensor, the MR6000 will automatically detect the model and set the appropriate scaling value.
Power is supplied from the current unit
Since current sensor power is supplied directly from the current unit, there’s no need to provide a sensor power supply.
