Limited operating temperature range
What is the limited operating temperature range? What is it for?
The standard operating temperature range for the Saga™ logger is -20°C to +50°C. The device is not intended for use outside of this temperature range.
The limited operating temperature range for the Saga™ logger is -30°C to -20°C (i.e., lower limited range) and +50°C to +70°C (i.e., upper limited range).
Warning
Functionality in the limited operating temperature range is only a backup option in case the temperature goes beyond the standard operating temperature range.
The device should not be in the limited operating temperature range for more than 6 hours.
Moreover, the device should never be used in temperatures outside the limited temperature range (i.e., below -30°C or above +70°C).
Tip
If you intend to track shipments in the lower limited range, please use Saga™ with the PR-T80 probe (i.e., an external temperature sensor).
How does the device behave in the limited operating temperature range?
In the limited temperature range, the device operates with limited functionality and reduced performance.
Battery capacity: affected, especially in the lower limited operating temperature range. The device may enter Hibernation Mode.
Full modem functionality: not guaranteed.
The device may not be able to send data when in the upper limited operating temperature range (+50°C to +70°C). To protect the battery in the lower range (-30°C to -20°C), it will not attempt to send data at all.
Location tracking: As location data is recorded during wake-ups (i.e. when sending data), location tracking is not guaranteed in the limited operating temperature range.
How accurate are the measurements in the limited operating temperature range?
Notice
The devices are not calibrated outside the standard operating temperature range.
The calibration points of the devices are correlated with the standard operating temperature range with a calibration accuracy of ±0.5°C to ±1°C.
Temperature measurement accuracy in the standard operating temperature range
While the logger is in the limited operating temperature range, it is expected to have a temperature accuracy of ±3°C.
