4.4.3 Display Settings
In the DISPLAY SETTINGS submenu the contrast of the display can be changed and the
peak hold function can be set-up.
Contrast
In the CONTRAST submenu the contrast of the main unit display can be adjusted.
Values between 0 and 99 can be entered. Also the display can be switched to
inverted colours.
Default value: not inverted, Level 30
Notice If by accident the display contrast has been set too high or too low so that
it cannot be read off anymore, this can be fixed as follows: Shut off the
Protec P3000 and switch it back on. During run-up press the third button
from the top on both sides of the display simultaneously until the contrast
is back to normal. This setting is not saved to the EEPROM but needs to
be confirmed manually through the contrast menu. Otherwise the Protec
P3000 will go back to the out of range setting after the next start-up.
Peak hold
The PEAK HOLD function can be enabled or disabled in this submenu. If the PEAK HOLD
function is enable the maximum leak rate will be displayed for a preset time in
addition to the currently measured value in the main display. The time setting will
have no effect if this function is disabled.
Default: value disabled, 5 s.
