Data Loggers and Accessories FAQ
Frequently asked questions about Tinytag data loggers and accessories.
The display on a Tinytag View 2 data logger will only show a reading whilst the unit is recording.
To start the unit recording, the unit must be launched using our Tinytag Explorer software.
If the display on your data logger has switched off this will be because the unit has stopped recording (this will either be due to the unit having completed it's logging run or because its battery has run flat).
If the battery in the logger has run flat, service kits for Tinytag View 2 units can be order using the part number SER-9550 from your usual supplier.
For most current data loggers, the Tinytag Explorer software will warn a user when the battery in their unit is getting flat*.
When data loggers are started in Tinytag Explorer the software checks the unit's battery status and advises the customer if it needs replacing. If the battery is very low, the software will prevent the user starting the unit so that data is not lost.
The battery status of a data logger can be checked at any time by performing a current reading in Tinytag Explorer.
There is no low battery warning on a data logger itself, the red LED most units are fitted with is part of the logger's alarm feature.
*The Tinytag Talk 2, Ultra 2, Plus 2, View 2, Aquatic 2 and Splash 2 data loggers are supported by the low battery feature in Tinytag Explorer.
No, by default your data logger will start recording as soon as it is launched using the Tinytag Explorer software.
The label refers to a feature in the data logger that enables a user, who isn't sure when they want to start recording, to set up their unit as they wish it to record and then start it at the exact moment they want to by swiping a magnet across the back of the unit.
To enable this feature, you should check the "Wait until trigger event" box in the Starting Options section of the Erase, Configure and Launch page in the Tinytag Explorer software.
Yes, thanks to the new Bulk Offload Tool if you have multiple USB ports, or a USB hub on you computer, it is possible to re-launch, download or get current readings from several data loggers at the same time. Simply run the tool and plug in your loggers, the tool will automatically detect them and perform the requested operation. When the progress bar reaches 100% the action is complete and another logger can be plugged in. Information downloaded from data loggers is automatically saved into a desktop directory for later analysis.
For further information on the Bulk Offload Tool, and how to use it, see here: Bulk Offload Tool.
We recommend units from our Tinytag Ultra 2 range for use in low pressure applications.
This advice only applies to Tinytag Ultra 2 loggers fitted with the supplied SB-AA02 battery (service kits including them are available from your supplier).
The SB-AA02 battery has been tested at 11.6K Pca (116 mBar/1.68 PSI) or less for a period of six hours at 20°C, in accordance with UN regulations on the transportation of lithium batteries.
When a liquid comes into contact with an RH sensor it effectively shorts it out and the data logger will start to read 100% RH.
In some cases, where the sensor becomes saturated, it is possible for the readings to "wrap" and for the logger to read 0% or just above.
Once the sensor has been able to dry out, and provided no residue is left on it, the unit should read correctly once more.
Yes, third party PT100 and PT1000 probes can be connected to our loggers as described here: Using Your Own PT100 or PT1000 Sensor.
