The first question you should ask yourself is “Do I want a button that can stop my logger from logging?”
If you are logging a shipment of goods, it might be handy to be able to stop the logger once the shipment arrives at its destination. If that is desired, there are a couple of ways to do it. First, you could configure your logger to stop after a certain number of days instead of rolling over – that way it will automatically stop when you want it to. Second, you could rely on someone at the destination pushing the Stop button. I know which sounds more reliable.
If you are monitoring a fridge or freezer, then having the Stop button enabled is probably not desirable, since it means that your logger can be stopped accidentally.
To enable the Stop button, tick this box on the Configure screen. To disable it, remove the tick.
As you would think, if you press and hold the Stop button, the logger will stop logging. It will no longer take any readings. However, you can still review the day statistics and download the logged results to a PC with LogTag Analyzer.
Once the logger is stopped, it can’t be restarted unless:
Ticking the Allow reset of logger with START button box has its own risks. If this enabled, anyone can wipe all the data of the logger with a simple button push.
Unless you have a really good reason to want the button enabled (and we can’t of many), we recommend that you untick the box on the Configure screen.
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.
