USB: Wrong Temperature Displayed or Expected

This article provides information on varying temperatures that may occur when using the USB device. If temperature is displayed incorrectly or not as expected, please review the following suggestions below to correct the issue.

Temperature is 5 to 10 degrees warmer than expected.

Conduction of heat from the PC/Server can warm the sensor a few degrees. This warming effect can vary depending on the processing load of the PC/Server. Using a USB extension cable can lessen the effect. However, since the sensor is mounted to the circuit board, the effect cannot be entirely overcome without an external probe (offered on our WiFi and Cellular units).

Temperature reads 32°F (or 0°C)

There are two possible causes for this temperature reading:

1. If the temperature is stuck on 32°F (or 0°C), there may be a driver issue. Please use the Driver Removal Tool, then try re-installing the driver.

2. If the 32°F (or 0°C) reading appears randomly during operation, you will either need to download and install hotfix 20100306.zip or upgrade to at least Temperature@lert version 4.0.

Temperature reads 185°F (or 85°C)

This is the initialization temperature reported by the sensor when communication is first initiated. Just like the issue above, you will  either need to download and install hotfix 20100306.zip or upgrade to Temperature@lert version 4.0. If this does not fix your issue the sensor may be damaged.

Temperature is Highly Inaccurate

Check if your sensor isn't located near a heating or cooling source. Also check your offset settings. If none of those apply, please try uninstalling the drivers and re-installing them using the Driver Removal Tool.
