Setting ranges
The setting ranges of the setpoints (possible minimum/maximum values) are limited by
the assigned start-of-scale values and full-scale values. Example:
• Changes to a measuring range can result in the setpoints assigned to the measuring
• The device displays the message "[150] - Parameter value invalid".
Adapt the setpoints. Make sure that the setpoints are within the valid measuring range.
2. Enter zero gas setpoints: .
"Zero gas range 1" to "Zero gas range 4" parameter boxes.
– Authorize access with Expert PIN, if necessary.
– The assignment of one setpoint is sufficient for a total calibration.
– Zero gas setpoint < span gas setpoint
