Frequently asked questions

To perform autozero, ensure the instrument is in clean air. For models without an electrovalve (CHEMIST 500B), ensure the gas probe is not inserted in the chimney during autozero.

The suggested settings for the data logger are: Mode: UNI 10389, Print: auto, Memory: auto (assigns a new memory at each instrument turn-on).

In the Memory menu, you can save individual measurements or analysis data. The instrument assigns a new memory location automatically when the 'Memory' setting is set to 'auto'.

To print a report, press the 'Report' context key. The instrument will start printing the analysis report based on the selected options and settings.

The CHEMIST 500 supports various fuel types, including: Natural gas, Propane, L.P.G., Butane, Diesel oil, Fuel oil, Propane-Air, and Biogas.
