Coefficient a x [CH A] (×, ÷, +, or -) coefficient b × [CH B] + coefficient c
(CH A and CH B may be any input channels' measurement data, selectable from CH1-1 to 4-15,
P1 to P8, or waveform calculation result channels W1 to W29 ((reused as inputs, as long as the
channel number is smaller than number of the final calculation result channel)). For example, to
obtain results on W3, [CHA] and [CHB] can be set to W1 and W2, respectively.)
The above formula is set up beforehand, calculation result waveforms are displayed on
the Waveform screen while measuring, and calculated values can be saved. Up to 30
calculation result waveform channels (W1 to W30) are available at once.
