Comment(by Quozl):

 XO-1.5 Measure 29.  Mono 3.5mm plug connected to CRO channel A via a BNC
 T-piece.  Probe connected to the same T-piece, and the other end to the
 0.5V 1kHz calibration point on the CRO panel.

  * in sound capture mode Measure properly showed the 1kHz square wave,
 though the amplitude and horizontal position became inconsistent when the
 amplitude control (RHS) was manipulated,

  * in resistance sensor capture mode Measure showed an almost straight
 line, with a slight square wave oscillation that looked to be about one or
 two pixels in height,

  * in voltage sensor capture mode Measure showed a straight line with no
 variation to level.
