– Enter start of measuring range: "Start-of-scale value" parameter field
– Enter end of measuring range: "Full-scale value" parameter field.
Note
Adjustment aid: Distance between the start of scale value and full-scale value
When setting the measuring range, the maximum or minimum values you can enter are
displayed in the corresponding editing window. But changing the start value and the end
value of a measuring range can violate the smallest measuring range span. The changes
are rejected in this case.
• You may have to change the setting sequence (full-scale value before start-of-scale
• Make sure that the smallest measuring range span is not violated. The smallest
Note
Setpoints for zero/span gas beyond the min./max. limits
After changing the start-of-scale value and/or the end-of-scale value, the setpoints for
zero/span gas may be outside the configured limits. The "[150] - Parameter value invalid"

measuring range span that can be set is 20% of the smallest measuring span. Refer
to the following example:
Smallest measuring span = 5000 ppm
⇒ at least 1000 ppm must lie between the start-of-scale value and full-scale value
(5000 ppm x 20% = 1000 ppm).
