This is a guide for connecting and using the UTRED30-WiFi and UTREL30-WiFi loggers with LogTag Online.
Open the back of the logger and install the two AAA batteries.
Open the LogTag Analyzer software and configure the logger – i.e. set the upper and lower alarms and the log interval.
In the LogTag Analyzer menu, choose LogTag Online, and click on Connection Wizard.
Log into the Wizard with your LogTag Online email and password.
Once you log into the Connection Wizard, the software will scan for connected devices.
When it finds your connected logger, it will take you to a screen where you can choose the Wi-Fi network you want to connect to, and enter your password.
The LogTag Mobile App allows users to access LogTag Online in an app instead of the internet browser and can be used by new or any existing users.
Latency, when it comes to temperature logging, refers to the delay between a change in temperature and when that change is detected and recorded by the logger. This delay can be due to the sensor’s design, the materials it’s placed in, or the logging interval. While it might sound like a disadvantage, latency can actually serve a useful purpose in certain environments—particularly where short-term temperature spikes are common but not harmful.
For example, in a busy commercial fridge, the temperature may briefly rise every time the door is opened. A logger with high latency won’t immediately react to these short fluctuations, helping to avoid unnecessary alarms or false data indicating a problem when there isn’t one. In these cases, a slight delay in response acts like a filter, focusing attention on real issues—such as prolonged exposure to unsafe temperatures—while ignoring the everyday ups and downs that don’t affect product quality or safety.
Depending on the type of logger you have, connecting your logger to your PC means either:
First Generation LogTags use a separate Reader (sometimes called a dock) for configuration and for downloading recorded data.
The Second Generation loggers only require a USB port or cable. Apart from saving the cost of the Reader, this makes them much better suited for shipping, because the recipient doesn’t need a LogTag Reader to download a report about the shipment’s journey.
