Setting the mixer frequency
In the SONAPHONE M, ultrasound is transformed into audible sound by
a frequency conversion process. The unit provides the option of setting
the working frequency via the mixer frequency. The frequency range
can be set between 20 and 60 kHz, in increments of 2 kHz. The default
value is 40 kHz. By turning the rotary know setting can be changed and
saved in the device. Press function key “F1” to return to the previous
menu and F3 return to the test mode.
Notice:
Changing the mixer frequency makes only sense when using
the probes L52 or L54, since these probes have the necessary
bandwidth.
Setting the test mode
The SONAPHONE M has two different display modes for the ultrasonic
test value, the linear mode (linear scale 0 - 240) and the logarithmic
mode (logarithmic scale 0 - 140). This can be set in the mode menu.
The element to be edited is selected by pressing the rotary knob, and
set by turning it. Press function key “F1” to return to the previous menu
and F3 return to the test mode.
Setting the temperature display
The SONAPHONE M provides the option of showing the temperature in
°C or in °F. The switch over between the two types of display can be
done in this menu. The element to be edited is selected by pressing the
rotary knob, and set by turning it. Press function key “F1” to return to the
previous menu and F3 return to the test mode.
