OPERATING INSTRUCTIONS
WORLD PRECISION INSTRUMENTS B-11
Tools Menu includes several tools to simplify and improve the acquisition
process.
• Auto Scale . Selecting this option ( Fig. B18 ) allows the user
to quickly find the signal within the plotting windows. This
option moves the vertical zero position and sets vertical
scale to an odd value.

About Menu ( Fig. B21 ) shows the
current version of the Apollo 4000 software.
• Zero option subrtacts the current value from the collected
data. The Zero menu (see Fig. B19 ) allows to reset each
channel individually, all together or unzero all of previously
“zeroed” channels. The subtracting value is acquired at the
moment of selecting the appropriate action. Zero operation
can be applied as many times as needed. The unzeroed
value is always displayed, too.
• Filter ( Fig. B20 ) applies a moving average digital filter to
the upcoming data. It helps to reduce noise and artifacts if
desirable. Note that the filter does not remove or substitute
data but rather makes the fast transitions of the signal
smoother. There are 10 different orders of filtering from 5
samples averaging (corresponding to filtering level 1) to 50
samples averaging (corresponding to filtering level 10). The
user must select
the most
appropriate filter
for the required
application.
