RF
The RF mode shows the waveform in a similar fashion to an oscilloscope. It shows
both the positive and the negative peaks. The peak (either positive or negative)
selected for measurement is shown in upper portion of the display.
It's important to note that a measurement must fall inside the displays viewable range
in order to see the waveform. However, even if the waveform is outside of the
viewable range of the display, a measurement can be taken and viewed on the digital
readout. If the wave 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 of the tabbed menu items.
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 MAX II 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 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 measurement labels F, also in the diagram.
E) Echo Signal – Graphical full waveform representation of the echo signal
displayed as an amplitude (vertical or "Y" axis) plotted against time (horizontal or
"X" axis), this time is then converted to a physical measurement in terms of a
specific quantity.
F) Measurement Labels – The measurement labels are calculated and displayed
based on where the left side of the display has been set (Delay), and the overall
viewable area (Width) of the display. Note: The gray hash marks break the
