Number of Decimal Places
When the screen displays the measured value in physical units (e.g.
ppm) the number of places after the decimal point depends on the size of
the set measuring range:
Span Places after the decimal point
£ 0.05
5
£ 0.5 4
£ 5
3
£ 50 2
£ 500
1
> 500 0
For the display of the measured value as a percentage of the whole
measuring range (%Span) two places are always shown after the decimal
point.
When setting the parameters, the number of decimal places is the same
as in the display in measuring mode.
