Hioki 8961 High Voltage Unit

  • Measuring in situations where high voltage exists between channels, such as three-phase inverters, requires a measurement instrument that has all input channels isolated
  • In addition, when measuring signals such as those of switching circuits that include common-mode voltage with a high-frequency component, the isolated circuit’s common-mode frequency rejection characteristics can greatly affect measurements
  • Used with the Hioki  8860-50 and 8861-50 Memory Hicorder
  • Accuracy at 23 ±5°C/73 ±9°F, 30 to 80 % rh after 30 minutes of warm-up time and zero-adjust; accuracy guaranteed for 1 year
