  • Page 36: Reading And Calibration Of Measured Values･･････････4-6

    4.3 Reading and calibration of measured values 4-3-1 How to read measured values The input level can be determined from the output amplitude and input from (7), (9), and (10) on the panel. If the sensor sensitivity of the acceleration sensor to be used is set to the unit, the relationship between the output voltage and the measured acceleration is as follows.
  • Page 37 4-3-3 Calibration 1) When the calibration voltage application switch is used The calibration voltage is output while the calibration voltage application switch is turned to the ON side. The calibration voltage in full scale (AC OUT: 10 Vpk, 20 Vp-p, DC OUT: 7.07 Vrms), 80 Hz sine wave, is output regardless of the range setting and sensor sensitivity setting, so it can be used to set the input range on the load side.
  • Page 38 Cautions 1. Dynamic range Set the measurement range so that the output is below full scale when in acceleration mode. If waveform distortion occurs due to scale over in the acceleration signal, large errors will occur in the velocity and displacement. With this product, when the acceleration signal frequency is about 16 Hz, the amplitude is the same as the acceleration amplitude even if the acceleration, velocity, displacement and UNIT are switched.
