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 40.
– 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.
