Maxim Integrated OneWireViewer, Version 1.5 - Manual (Page 11)

Sample Real-Time Temperature Tab
When the Real-Time Temperature tab is active, the Real-Time Temperature viewer:
Continuously issues the device-specific command to perform a temperature conversion.
After each conversion reads the temperature registers of the selected device.
Converts the reading from the device-specific format into a conventional format.
Displays the result as a number, graph, and thermometer scale.
Compresses the horizontal scale of the graph, as needed, to display additional readings.
Allows the temperature scale to be changed between °C (default) and °F; the selected scale is memorized.
Allows the resolution of the temperature display (some devices only) to be changed.
Allows activation of automatic rescaling of the graph.
Allows graph data to be exported by using the clipboard or saving as a CSV (Excel) file.
Notes:
The Real-Time Temperature viewer closes whenever the selected device is found to be missing from the network or when another device is selected.
To keep the Real-Time Temperature viewer running while evaluating other devices, first activate the Real-Time Temperature viewer. Then on the View menu
(see Program Main Window), select Show Tab in New Window which will restart the Real-Time Temperature viewer in a new window. This separate window
will remain open, even if the device disappears from the network.
With the DS1922L, DS1922T, and DS1923, the temperature readings displayed are software corrected. For the DS1922E, software correction does not apply.
The Real-Time Temperature viewer cannot read the temperature of a Thermochron (DS1921, DS1922, or DS1923) that is currently running a mission.
Real-Time Humidity
The Real-Time Humidity viewer gives a real-time humidity reading of the selected 1-Wire humidity device connected to the OneWireViewer. The real-time humidity
log on the screen is created from humidity data stored in the PC's memory. This is different from Mission viewer, where the humidity logging is performed inside an
iButton whether or not it is connected to the OneWireViewer.
The tab of the Real-Time Humidity viewer consists of three areas: Info (top), Graph (bottom left), and Humidity (bottom right). Depending on the size of the
Humidity tab, there may be scroll bars for the graph and/or humidity area. The Real-Time Humidity viewer applies primarily to the DS1923. The viewer may also
support other devices that can be set up to measure humidity. See the Supported Devices table above for the list of devices.
