Maxim Integrated OneWireViewer, Version 1.5 - Manual (Page 7)

Start New Mission Window (default)
It is recommended that you synchronize the device's real-time clock (RTC) to the PC. Enter the mission start delay in minutes. Sampling rate, mission start delay,
temperature alarms, and rollover depend on the technical requirements of the mission. See the respective DS1921-series data sheets for guidelines. The clock
alarm functions are not relevant for a device on a mission. The default settings, therefore, can be accepted.
Notes:
The time reference in the alarm log (e.g., "Low alarm started at: 21") indicates minutes after the start of the mission. To find the day and time when the alarm
occurred, manually add the indicated time to the mission start date and time.
The Thermochron viewer does not enable the temperature-high and temperature-low alarm search. As a result, if a temperature alarm occurs during the
mission, the device will not be identified as an alarming device unless there is also a timer alarm.
For the alarm-frequency and alarm-time values to be updated in the device, Enable Clock Alarm? must be checked. Otherwise, the current (i.e., previous
mission's) settings remain in effect for the new mission.
When a mission extends across time zones, the time shown in the exported data (clipboard or csv file) refers to the time at the location where the mission was
started.
Mission (Temperature and Humidity Logging)
The Mission viewer gives real-time information on the mission parameters and status of the selected Temperature Logger iButton connected to the OneWireViewer.
The user can start a new mission, end (disable) a running mission, view and download the mission's temperature and humidity. The Mission viewer is similar to the
Thermochron viewer, but is used for the DS1922 series of iButton products, the DS1923 Hygrochron and its features, and the DS2422 1-Wire temperature/data
logger. See also the Supported Devices table above.
The tab structure of the Mission viewer consists of two areas: Command (top), and device data tabs (bottom). The Command tab includes three buttons to operate
the logging function of the device, and to select the temperature scale (°C or °F). Depending on the size of the Mission tab, there may be scroll bars for both areas.
