2. Then press the SCAN or ALARM button to change the speed of sound.

4.5 The ultrasound image mode ( scan mode)
While the instrument excels in single point measurements, it is sometimes desirable to
examine a larger area to look for the thinnest point. This instrument has a scan mode
feature that allows you to do just that.
In normal operation, four measurements are taken per second, which is very
appropriate for single measurements. In scan mode this is ten measurements per
second and the readings are shown on the display. While the transducer is in contact
with the material to be measured, the instrument automatically searches for the
smallest reading. The transducer can be "scrubbed" over the surface, because short
interruptions of the signal are ignored. In the case of interruptions lasting longer than
two seconds, the smallest measured value found is displayed. If the transducer is lifted,
the smallest measured value found is also displayed.
When the scan mode is switched off, the single point measuring mode is automatically
switched on.
The scan mode can be switched off as follows:
The key
is pressed to switch it on or off. The current state of the scan mode appears
on the screen.
4.6 Change the resolution
The device TN xx0.01 US has two selectable screen resolutions, 0.1mm and 0.01mm.
This option is not available for the TN xx0.1 US device. It is limited here to 0.1mm.
If the key is pressed
(high) and "low" (low).
4.7 Changing the units
Starting from the measuring mode, the unit can be changed by pressing
selecting between mm (metric) and inch (English).
4.8 Storage management
4.8.1 Saving a meter reading
The measured values can be stored in the device with 20 files (F00-F19). For each file
there are at least 100 registers (material thickness values) that can be stored. If the
key
is pressed after a new reading is displayed, the measured material thickness is
stored in the current, running file. If you want to change the file in which the measured
values are stored, proceed as follows:
1. Press the key to
file name and the total number of all data records in the file.
2. Use the and
