Listening to the Instrument
The UltraLyte emits a variety of ticks and tones
when it takes readings. The sounds vary depending
on what the instrument is doing, and with experience
you can tell what is happening during a
measurement simply by listening.
The tones it emits are summarized in the table at
right.
Sound Meaning
Single high-pitched
tone
The instrument succeeded in
taking the intended
measurement.
Single low-pitched tone
The instrument was unable to
take the intended measurement
due to an error. An error code
displays on the back panel screen
to indicate the nature of the error.
See
Error Indicators,
later in this
manual, for details.
Low-pitched growl
The instrument is attempting to
lock onto a target.
Fast ticking
In Time Over Distance mode, the
instrument is timing the intended
target.
High-pitched, oscillating
ring
Jam tone. The instrument’s laser
return sensor is being
overwhelmed by light.
