DataView II (CD295) Dual Line Display

22

9. Temperature Extremes and LCD Adjustment

The CD295 has been tested to –20 ºC. It will perform at this temperature

although the display may be sluggish and dim.

Under temperature extremes, the CD295 liquid crystal display (LCD) may

become difficult to read. LCD contrast can be adjusted by inserting a small

jeweler’s screwdriver (preferably plastic) into the round hole on the back of the

CD295 cover and adjusting the LCD contrast potentiometer.
