PX-7 Ultrasonic Thickness Gauge
5
The
SCAN
key switches the
SCAN
measurement mode on and off.
Refer to page 17 for an explanation of the
SCAN
measurement mode.
The
DOWN
arrow key has three functions. When the
PX-7
is in the
CAL
mode, this key is used to decrease numeric values on the display. An
auto-repeat function is built in, so that when the key is held down, numeric
values will decrement at an increasing rate. When the
PX-7
is not in
calibration mode, the
DOWN
arrow key switches the display backlight
between three available settings.
OFF
will be displayed when the backlight
is switched off.
AUTO
will be displayed when the backlight is set to
automatic mode, and
ON
will be displayed when the backlight is set to stay
on. In the
AUTO
setting, the backlight will illuminate while the
PX-7
is
making a measurement and turn off after several seconds to conserve
battery life. Finally, if the
DOWN
arrow key is pressed and held down while
powering the
PX-7
on, a
LOC
mode will be toggled on/off.
