Initial Setup
61
The 38DL PLUS automatically uses the fastest update rate when entering the
Minimum or Maximum mode (see “Using the Minimum, Maximum, or Min/Max
Thickness Mode” on page 115).
To adjust the measurement update rate
1. From the measurement screen, press [SETUP MENU].
2. In the menu, select MEAS.
3. In the MEAS screen, set the MEASURE RATE to the desired value.
4. Press [MEAS] to return to the measurement screen.
4.7 Changing the Thickness Resolution
You can 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 dual element transducer is 0.01 mm (0.001 in.). The velocity is always reported
with full four-digit resolution.
You can reduce the resolution in some 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 high resolution software option (P/N: 38DLP-HR [U8147015]) allows to increase
the resolution to 0.001 mm (0.0001 in.). The high resolution is available for measured
thickness smaller than 102 mm (4 in.). The high resolution is not active with low-
frequency transducers and when the high penetration software option is activated.
To change the thickness measurement resolution
1. Press [SETUP MENU].
2. In the menu, select MEAS.
3. In the MEAS screen, set RESOLUTION to the desired option:
— STANDARD: 0.01 mm or 0.001 in. (default)
