The I30 is an AC/DC current clamp based on Hall effect technology designed for accurate non-intrusive measurement of both DC and AC currents. It features a specified current range of 30 mA to 30 A DC and 30 mA to 20 A AC rms, with a usable range extending down to 5 mA DC. The device delivers an output sensitivity of 100 mV/A with an accuracy of ±1% of reading ±2 mA at +25°C, and operates across a frequency range from DC to 20 kHz. The I30 is compatible with multimeters, recorders, and other recording instruments, making it ideal for field measurements, troubleshooting, and monitoring applications in electrical systems where direct circuit interruption is impractical or undesirable.
