Hioki 3290 CLAMP ON AC/DC HiTESTER

The 3290 CLAMP ON AC/DC HiTESTER is used with the CT9691 (9691), CT9692 (9692), or CT9693 (9693) CLAMP ON AC/DC SENSOR. These sensors are interchangeable and any model can be used with the 3290. The 3290 automatically detects the sensor connected and sets up the appropriate range. When combined with the CT9691 (9691), CT9692 (9692), or CT9693 (9693) Sensor, the 3290 HiTESTER can perform DC, AC, and AC+DC measurement of a live power line. Various functions are available (using the SHIFT key) to make the 3290 suitable for various current measurement applications. The 3290 is also equipped with two output terminals to enable a variety of advanced measurements, such as simultaneous output of both monitor and rms record. Moreover, the 3290 can operate using battery power or the AC adapter (for long-term measurement use).

Features

• AC+DC mode measures true rms current of full- and half-wave rectifi ed waveforms and inverter output waveforms from 1 Hz
• Peak mode measures the maximum waveform amplitude of in-rush current at device startup
• Maximum, Minimum and Mean value modes easily measure current variations in lines with severely fl uctuating loads
• Simultaneous waveform and rms output enables rms and waveform or frequency fl uctuations to be externally recorded together
• Selectable measurement response time enables setting the instrument response to suit changes in load current
• LPF (fc = 550 Hz) fi lters out unnecessary harmonic currents and noise
