3. Set up the measuring range:
Refer to the specifications under → Overview of measuring ranges (Page 95).
– 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"
message is displayed:
• Make sure that the measuring range is active.
• Adjust the setpoints to the changed measuring range.
4. Enable/disable measuring range: "Use measuring range" parameter field.
Note
Using measuring ranges in other device functions/menus
Other device functions or menus can only access measuring ranges activated in this
menu. Inactive measuring ranges are not displayed for selection in other device
functions/menus. This means they can no longer be used, for example, in autoranging or
in calibrations.
5. Set additional measuring ranges/parameters, e.g., → Setting Autoranging (Page 98).

value)
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 be between the start
of scale value and full-scale value (5000 ppm x 20% = 1000 ppm).
