HIGH VOLTAGE UNIT 8961

CE
OVERVIEW  
Directly input high voltages and measure instantaneous and RMS waveforms
  • Insulated input (Voltage to earth : 600 V AC/DC in measurement category 3, and 1000 V AC/DC in measurement category 2)
  • 16-bit A/D conversion facilitates high resolution measurements
  • Built-in true RMS rectified circuit with a wide band from low to high frequencies (DC, or 40 Hz to 10 kHz)
  • Observe instantaneous waveforms of DC and wide band AC signals (DC to 100 kHz)
  • Bundled with dedicated input cables
When using with the MEMORY HiCORDER 8860/8861, a firmware upgrade of the HiCORDER may be necessary. Install only up to four units in one 8860 series MEMORY HiCORDER
Basic specifications (accuracy guaranteed for 1 year)
Measurement functions Number of channels: 2, for voltage measurement, DC/RMS selectable
Input terminals Safety banana terminals (input impedance 10 Mω, input capacitance 5 pF or less), Max. rated voltage to earth: 1000 V AC/DC in CAT II, 600 V AC/DC in CAT III (the maximum voltage that can be applied between input channel and chassis and between input channels without damage)
Measurement range 1 V to 50 V/div, 6 ranges, full scale: 20 div, AC voltage for possible measurement/display using the memory function: 700 V rms, low-pass filter: 5/50/500/5 kHz
Measurement resolution 1/1600 of measurement range (using 16-bit A/D conversion and when installed in 8860 series)
Highest sampling rate 2 MS/s (simultaneous sampling in 2 channels)
Accuracy DC amplitude: ±0.25% of full scale (with filter 5 Hz), zero position : ±0.15% of full scale (with filter 5 Hz, after zero adjustment)
RMS measurement RMS amplitude accuracy: ±1% of full scale (DC, 40 Hz to 1 kHz, sine waveform), crest factor: 2
Frequency characteristics DC to 100 kHz ±3dB
Input coupling DC, GND
Max. allowable input 1000 V DC (the maximum voltage that can be applied across input pins without damage)
Number of installable units Install only up to four units in one 8860 series MEMORY HiCORDER
