Sample and Adjust vs OT Toolbox

Sample and Adjust supports adjustment of Endress+Hauser Promass concentration measurement to match results from laboratory or other reference measurement. The App automatically registers the relevant data from Promass during sample taking via Wi-Fi connection. Information about process stability and device diagnostics is provided to evaluate sample quality. Based on the result from laboratory analysis Sample and Adjust adjusts Promass concentration function and updates it accordingly. Currently implemented: - Adjustment on concentration profile 1 for Promass 300/500 with concentration package - Single point offset adjustment only - Basic workflow: o Connection via Wi-Fi to Promass o Process Check o Sample data recording o Input of reference (laboratory) value o Calculation of new concentration function o Transfer of adjusted concentration function to device - To do creation (Reconnect to device after To do creation not yet implemented) - Demo mode by selecting mock data in Settings
