LogTag Errors

If you get an error when trying to read the data from your logger, here is some useful information.

Why can’t I see the LogTag interface?

No LogTag Interface

If you go to download or configure a first generation LogTag, and you see a red X next to Locate cradled LogTag(s), it means that LogTag Analyzer could not find a connected Reader.

What is Pre-Start Logging?

LogTag Pre-Start Logging

Even if the “Start” button isn’t pressed, a LogTag configured with pre-start logging will still record temperature data, ensuring critical readings aren’t lost due to user oversight, but there are some catches.

Latency explained

What is latency?

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.

Differrnt connections

Connecting your logger

Depending on the type of logger you have, connecting your logger to your PC means either:

  • inserting into the Reader,
  • plugging it into a USB port, or
  • connecting it via a USB cable.

What's so good about USB?

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.
