1.8.10 Adjusting the LCD Contrast and Brightness
Using these potentiometers for the LCD adjustment, complete the following steps:
Note:
If the Sentinel is to be mounted in a non-hazardous location, the following adjustments may be made after
the installation is complete.
WARNING!
1.
Make sure the Sentinel is in a safe environment.
2.
Loosen the set screw on the enclosure #1 front cover.
3.
Place a rod or long screwdriver across the cover in the slots provided, and rotate the front cover
counterclockwise until it comes free from the enclosure.
4.
With power applied to the meter (see "Wiring the Line Power" on page xxvi), carefully use a small screwdriver to
adjust the LCD brightness. Turning the BKLT (backlight) pot fully clockwise yields maximum brightness.
5. In a similar manner, adjust the CONT (contrast) pot to set the LCD contrast as desired. At either extreme of the
CONT pot, the display is unreadable. Turn the pot fully counterclockwise and then turn it clockwise very slowly
until the display is clear.
6. After the desired LCD adjustments have been made, replace the meter front cover and proceed with the
installation.
