4.6 Changing the Thickness Resolution
It is possible to change the thickness-measurement resolution, meaning the number of
digits shown to the right of the decimal point. The resolution selection affects all
displays and data output of values with thickness units. This includes measured
thickness, differential reference value, and alarm set points. The highest thickness
resolution with a dual element transducer is 0.01 mm (or 0.001 in.). The velocity is
always reported with full four-digit resolution.
The resolution can be reduced in certain applications where the extra precision of the
last digit is not required, or where extremely rough outside or inside surfaces make
the last thickness display digit unreliable.
The Single Element including High Resolution software option (P/N: 45MG-SE
[U8147022]) makes it possible to increase the resolution to 0.001 mm (or 0.0001 in.).
High resolution is available for measured thickness smaller than 102 mm (4 in.). High
resolution is not active with low-frequency transducers, or when the High Penetration
software option is activated.
To change the thickness-measurement resolution
1. In the measurement screen, press [SETUP] , and then select MEAS .
2. In the MEAS screen (see Figure 8-1 on page 142), set RESOLUTION to the
desired option:
•
STANDARD : 0.01 mm (or 0.001 in.) [default]
• LOW : 0.1 mm (or 0.01 in.)
• Optional HIGH : 0.001 mm (or 0.0001 in.)
3. Press [MEAS] to return to the measurement screen.
