There are four statistical qualifications of the reflected signal:
• NO TARGET REFLECTION – when a steady reflected
signal isn’t received. Numerical display shows four dashes at
the distance displaying area;
• TARGET REFLECTION LOW – when the number of
steady received reflected signals is just enough to make
acceptable conclusion about the measured distance;
• TARGET REFLECTION MED - when the number of
steady received reflected signals is in medium range and
enough to make positive conclusion about the measured
distance;
• TARGET REFLECTION HIGH - when the number of
steady received reflected signals is qualified to be enough to
make reliable conclusion about the measured distance.
The displayed statistical qualification of the reflected signal
characterizes variation in expected accuracy of measurements. At
qualification HIGH the accuracy of measurements is stated as
±1m ±
0.1%. At lower rates of statistical qualification the
expected accuracy may marginally degrade.
The display presents message LOW BAT – when voltage of
the primary 9-volt battery drops below 7.2 volt. At this point the
System is still functional but the battery should be replaced as
soon as possible. The System can operate at the voltage level
above 7 volt. Alkaline or lithium type of batteries capable to
sustain current drain up to 150 mA should be used for powering
the System.
