To Set the Number of Digits
You can set the display to show 4½, 5½, 6½, or 7½ digits. In this book, the most 
significant digit (leftmost on the display) is referred to as the “½” digit, since it can 
only be a “0” or “1”. The number of digits displayed also depends upon the 
integration time set, see page 33.
– The number of digits is set to 6½ digits at power-on and after a remote 
interface reset.
– The number of digits shown is dependent upon integration time and filter 
settings. The meter will not allow you to show more digits than the practical 
measurement capability of the meter. You can, however, reduce the number of 
digits shown.
