This function is activated via the OdaStat-G™ software package, “Instrument Parameters” section, by selecting
the “Suppress Negative Reading” option.
Once active, the instrument suppresses all negative readings to the display and the logging memory.
If the instrument drifts negative by more than 2.5% of full scale or less as per factory configuration, the
instrument will display the message “do nuLL”. This indicates that the instrument needs a NULL (Fresh Air
Zero) as per Section 9.5. It is essential that the NULL be performed in ‘clean air’.
