7.5.1 The Instrument Setup Menu
7.5.1.1 Unit Setup
The first point of the submenu allows choosing the units used for indication, ppm or Vol.%.
By choosing Vol.% the operator may determine the number of digits after the dot.
With ppm the resolution is always 1ppm. In order to choice the desired unit, mark the first line.
Pressing <ENTER> the unit will alternate between ppm and Vol.%.

Note!
Internal calculation is always done on ppm level. Access of measuring values via the RS232
interface will always give the numbers in ppm with 1 ppm resolution.
