Scaling the display range

The sca ling of the dis play ran ge is mat ched by using a sca ling- fac tor and an offset va -
lue. The calcu la ti on of the dis play va lue looks like be low:

The over flow or un der flow be co mes ac ti ve, if the dis played va lue is grea ter than
999999 or smal ler than -99999.
• When

 over flow 

is ac tiv the dis play shows

 “nnnnnn”

• When

  un der flow
