6 Measuring of signal accuracy (only ATU-2)
-
Check the geometrical mounting conditions (use Mounting Instructions
http://www.amo-

-
Before measuring of signal accuracy ensure that you get no error for total measuring distance
using Position measurement function.
-
If the ATU Box was connected successfully, you can measure signal accuracy by activating of
“Signal accuracy” window.
The signal deviations can be evaluated by moving the measuring head along the scale (or
measuring flange) with a constant speed.
Setting the speed precision and number of periods
Here you have an opportunity to set measurement speed precision (between 1 and 30%) and
minimal periods quantity for measurement (between 50 and 2100). The precision of evaluation is
higher for uniform speed (e.g.
Speed precision
below 10%) and longer measuring stroke (e.g.
Minimal periods
higher than 70). Try to optimize these two values in order to get higer signal
accuracy value.
Getting a higher speed accuracy score means a higher mounting accuracy according to Mounting
Instructions.
-
To start measurement process click “Start” button. If measurement goes correct, you will see
progress field filling.
-
After getting valid measurement data, you will see signal accuracy and the speed deviation in the
same-named field.
-
To abort measurement process click “Stop” button.
-
Before closing programm, please break connection with ATU Box by clicking “Device connected”
button.
