3.4. Assignment of controls and indication
3.4.1. Graphic liquid crystal screen 3 is used to screen
graphic and digital information during the operation of the
metal stress scanner.
3.4.2. Button 4 is used to turn on the electric power of
the metal stress scanner.
When you turn on button 4, the logo of Spector Sci-
Tech LLC appears on the stress scanner screen for a short time
with information about the type of stress scanner (Fig.3.4 a).
After setting the measurement mode, the stress scanner
screen displays digital readings of the sensor output signal (in
mT or MPa), time, battery charge level of the metal stress
scanner, and service messages (Fig.3.4 b, c).
3.4.3. Button 5 is used to turn on the stress scanner
screen backlight. When you turn on button 5, the screen is
illuminated with additional light to improve the screen of
digital readings.
3.4.4. Button 6 is used to switch the measurement mode
of the metal stress scanner.
When button 6 is enabled, the stress scanner switches
to dynamic measurement mode. In dynamic measurement
mode, the stress scanner screen displays a digital reading and a
graph of the change in the value of the sensor output signal
during continuous scanning of the metal surface (in mT or
MPa), the set measurement mode, the battery charge level, the
current time and service messages (Fig.3.4 c).
When button 6 is turned off, the stress scanner switches
to static measurement mode. In the static measurement mode,
the stress scanner screen displays a digital indication of the
sensor output signal value (in mT or MPa), measurement
mode, battery charge level, the current time and service
messages (Fig.3.4 b).
