RMS-App Further function

Device	- Firmware update / downgrade - Restart (remote device reset) - Links to device documentation - Live device information
Measurement	- Measurement value (numeric and chart)
Configuration	- Please click first the Read button. Then configure and click on the write button. - NTC: The sensor can be configured by Use sensor data file or Use R25 / B NTC parameter. The sensor data file is used if the user chose a Rotronic standard NTC sensor (Temperature NTC). The R25 / B NTC parameter are used if the user wants to integrate an non Rotronic standard NTC sensor. - Simulator: A simulated (not real measured) temperature value can be set and enabled. It is used for system validation. - RMS service URL: Link to the RMS server, to that the logger sends data. - WiFi: Maximum 10 WiFi networks can be stored in the logger. If the current used is not available (interrupt, change of password, change of location etc.), than the logger scans for available networks, compares to this settings and connects to the known WiFi network with the strongest signal strength. \	Note: This WiFi-scan is energy consuming. If the logger is battery powered, please take care, that the standards WiFi access point / router is in a range with good signal strength to not use too much of the battery capacity / lifetime. \	\	--- \

Logfile	- Download data: current log data (max. 44'000 measurement values) can be downloaded, visualized on a chart or exported into a *.csv file for further analysis manually. The log data can also be deleted. - Download audit trail: The device-internal audit trail contain information about the system health of the device as extraordinary communication. It is very helpful for further system analysis. By clicking the butten Download audit trail, these information can be exported into a *.csv file.
Adjust	- The measurement chart is very helpful to judge wether the current measurement is stable for adjustment. - In this field, the user can acquire and adjust reference and measured values. (See Adjustment at chapter Device description). Chart and trend indicators can be used to judge whether the climate, UUT and reference are stabilized. - Adjust info contain all current adjustment (production and customer adjustment) information stored in the logger.
