Besides 3- and 4-digit digital indicators, there are also 3 1/2-digit indicators available in the market. But exactly what is a 1/2 digit?
A full digit can indicate all numbers from ?0? to ?9?. A 1/2 digit, in contrast, can only display a ?1?, lots ?2? or higher is not possible. With a 3 1/2-digit digital indicator, the indicatable selection of values is thus significantly limited in comparison with a 4-digit indicator.
Thus, on the one hand, the maximum of the indicatable range of values is only 1999 rather than 9999. On the other hand, no negative values could be indicated, because the minus sign can’t be displayed in the first position. Therefore, the minimum of the indicatable selection of values is 0 instead of -1999.
An exception to the limitation of the indicatable negative value range is represented by indicators which have another space for the display of the sign. pressure gauge octa with this characteristic can therefore also indicate values down to -1999.
