985V_data_english 7021-5 Technical data subject to change without prior notice. Configuration of volume flow or flow velocity 1. Jumper 1 open: Select a calculation formula and enter the k-factor. This procedure is used when the k-factor is known. The k-factor can be found, for example, in documentation provided by the manufacturer of the ventilator or the probe. Use the menu guide on the device for configuration. 2. jumper 1 closed: Creating reference volume flow or flow velocity. Create a reference volume flow or flow velocity to configure the device without selecting a formula and...
