• Other parameters
Histo
: Frequency distribution of voltage values
Int1TY : Area under positive amplitude
Int2TY : (Area under positive amplitude) – (area under negative amplitude)
Int1XY : Summation of triangular area in X-Y waveform
Ing2XY: Summation of trapezoidal area in X-Y waveform
* For details about area calculations, refer to Appendix 3 (page App-4).
Restrictions and precautions
• The automatic measurement of waveform parameters is performed on the data acquired in the
acquisition memory not the data displayed on the screen. Therefore, the frequency
distribution of the data may not match the waveform that are zoomed vertically (settings
other than “
×
1” on the voltage module or 32-bits extendered Logic Imput) or the waveform
of temperature/strain module.
• If measurement was impossible, the screen displays “***” in place of the value.
• Waveforms with small amplitudes may return incorrect measurement results.
• If the measurement area contains more than one period, measurement is carried out on the
first period only.
• Measurement results may in some cases be inconsistent with the displayed waveform, since
automatic measurement is not synchronized with the display update. You can ensure
consistency by stopping the waveform acquisition.
• Logic waveform (Logic Input Module or 32-bits extended Logic Input) cannot be
automatically measured.
• If the input signal is that of a temperature module, the following parameters cannot be
automatically measured for any other unit besides “˚C.”
