Up Arrow Key
The UP arrow key has two functions. When the MINI-
TEST 403 is in calibration mode, this key is used to
increase numeric values on the display. An auto-repeat
function is built in, so that when the key is held down,
numeric values will increment at an increasing rate.
When the MINITEST 403 is not in calibration mode, the
UP arrow key switches the SCAN measurement mode
on and off. Refer to section „SCAN Mode“ for an
explanation of the SCAN measurement mode.
Down Arrow Key
The DOWN arrow key has two functions. When the
MINITEST 403 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 MINITEST 403 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 when
the MINITEST 403 is actually making a measurement.
