Hioki 8972
DC/RMS Input Module
Product Highlights
- Instantly measure waveforms and RMS graphs from DC to AC
- 12-bit A/D resolution
- From low to high frequency, wide band width RMS rectifier installed (DC, or 30Hz to 100kHz)
- Monitor instantaneous waveforms without the need to pass through the rectifying circuit
- Isolated input, up to 300 V AC/DC from the earth
- Use with the MEMORY HiCORDER 8847, Input cables are not supplied
- Accuracy at 23 ±5 °C/73 ±9 °F, 20 to 80 % rh after 30 minutes of warm-up time and zero adjustment; accuracy/product guaranteed for 1 year
- Measurement functions Number of channels: 2, for voltage measurement, DC/RMS selectable
- Input connectors Isolated BNC connector (input impedance 1M?, input capacitance 30pF), Max. rated voltage to earth: 300V AC, DC (with input isolated from the unit, the maximum voltage that can be applied between input channel and chassis and between input channels without damage)
- Measurement range 5mV to 20V/div, 12ranges, full scale: 20div, (AC voltage for possible measurement/display using the memory function: 280V rms) Low-pass filter: 5/50/500Hz, 5k/100kHz
- Measurement resolution 1/100 of measurement range (using 12-bit A/D conversion and when installed in 8847)
- Highest sampling rate 1MS/s (simultaneous sampling across 2 channels)
- Measurement accuracy ±0.5% of full scale (with filter 5Hz, zero position accuracy included)
- RMS measurement RMS amplitude accuracy: ±1% of full scale (DC, 30Hz to 1kHz), ±3% of full scale (1kHz to 100kHz), Response time: SLOW 5s (rise time from 0 to 90% of full scale), MID 800ms (rise time from 0 to 90% of full scale), FAST 100ms (rise time from 0 to 90% of full scale), Crest factor: 2
- Frequency characteristics DC to 400kHz -3dB, with AC coupling: 7Hz to 400kHz -3dB
- Input coupling AC/DC/GND
- Max. allowable input 400V DC (the maximum voltage that can be applied across input pins without damage)
- Dimensions, mass 106mm (4.17in) W × 19.8mm (0.78in) H × 196.5mm (7.74in) D, 250g (8.8oz)
