The rectified A-Scan mode shows half of the waveform. Either the positive or
negative peaks are displayed, depending on the polarity selected.
It’s important to note that a measurement must fall inside the viewable display
range in order to see the waveform. However, even if the waveform is outside of
the viewable area, a measurement can be taken and viewed on the digital
readout. If the waveform is outside of the display range, you can manually
change the range by adjusting the
Delay and Width values, or you can use the
Auto Find feature located in the UTIL menu in the tabbed menu items. Re fer to

The following is a list of the viewable features on the display:
A) Stability of Reading Indicator – Indicates the stability of the return echo on
a scale of 1 to 6 – the solid bars displayed in the figure above indicate a
repeatable signal. If the MINI-MAX is displaying a reading from memory, the
repeatability indicator will be replaced by the text
“MEM”.
B) Battery life indicator – Fully charged batteries will appear filled in solid.
Note: The diagram shows the batteries at approximately 50%.
C) Length Measurement – Digital readout of quantity (english or metric).
D) Detect Indicator – The broken vertical line displays the zero crossing (flank)
detection point on the waveform where the measurement has been obtained.
Notice that the digital quantity readout is the same as the location of the
detect indicator according to the measurements labels F, also in the diagram.
