A2Microsoft .NET Framework 4.7 or above.

A3No, users can't calibrate the XHlogger, but they can use the “offset” function to tune the temperature or humidity.

A4Yes. The data logger XH10 has the option in the configuration for the device time zone.

A5Downloaded data are stored in a binary file which is a proprietary secure format that is tamper proof. This is a requirement in many applications and standards (such as the FDA 21 CFR Part 11 in the US). Binary files can only be accessed and viewed by Data Logger Viewer application software, so if another person wishes to view the data on different computer then  the data needs to be exported to another format. Data Logger viewer can export data to formats capable of being imported by other applications such as MS Excel, PDF, JPEG however, data exported this way are no longer secure/tamper proof.

A6The data logger viewer software have the option to export the data to JPEG, CSV and PDF

A7XHLogger LCD shows the memory status on the screen. The user can know the memory status from the memory display and also from the software_DLV shows the memory status.

A8The XH10 data logger has the internal memory of 100 files with 80,000 logs/file subject to total of 200,192 logs.

A9XH10 data logger LCD displays battery status on the home screen. The user can know the battery life from this display, or the Datalogger is connecting with PC, DLV also shows the battery status.

The typical life time of the battery is 12 months. Unfortunately there is no clear cut answer to this question. Battery life is affected by many different factors:

1. If the logger is permanently used in very cold temperatures (<-20°C for example) battery life is reduced as the battery needs to work considerably harder to deliver the required power
2. If the logger is permanently used in very hot temperatures (>50°C for example) the battery\'s internal self discharge increases as does the average current drawn by the electronics, hence battery life decreases
3. If the download rate is high, battery life decreases
4. If the alert LED blinks often, more power is used and battery life decreases
5. If the logging rate is high, more power is used and the battery life decreases
6. If the logger is shutdown between uses, battery life increases as the power consumption is at a minimum.
7. XH10 data logger units have replaceable batteries.

It should also be noted that not all battery cells have exactly the same characteristics. Although they are manufactured to stringent quality specifications, some cells have a naturally longer life than others due to the processes used in their manufacture.

The published specifications can therefore be only a guideline when the product is used in normal conditions, based on monthly download and 15minute logging. Clients have reported shorter battery life for applications of frequent downloading (twice a day) with relatively rapid logging (every minute or less). At the other end of the spectrum we have seen the battery life exceeds 3 year battery life, particularly if they are shutdown between uses.

A11Yes. The XH10 logger has the removable battery. It can be easily replaceable by the user.

A12Sorry, external temperature sensors can not be connected with XH10.
