Description
Zeros your gauge in much the same way that a mechanical
micrometer is zeroed. If your gauge is not zeroed correctly,
all of the measurements made may be in error by some
fixed value. You can choose between automatic zero or
manual zero.
Use this function to select the type of transducer being used
from a chart of transducer types. This provides increased
linearity between transducers.
When operating in pulse-echo mode this function provides
manual control of the amplitude of the signal (options are
Low, Medium and High).
When operating in echo-echo mode your gauge switches to
automatic gain control and this function is not available.
Gain is similar to the volume control on a stereo receiver.
Choose which measurement mode to use.
