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. This is the
preferred mode for thin precision measuring modes, using delay line and pencil style
transducers.
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. Refer to page 72 for
additional information on the Auto Find feature.
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 PVX 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%.
