The device will not take measurements when there is no power but all readings it has taken prior to the loss of power will be synchronized. Once the battery is changed, the device will start the recording session, and continue recording. You must set suitable sample and transmission rates as these will affect your battery life.
XHLogger 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.
XH10 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.
If somehow, a device can’t respond to a user, the user can press START, ROLL and STOP three keys simultaneously to bring the device back to the monitoring mode.
Once the user press STOP key for more than three seconds while the device is at logging mode, the monitoring mode starts. The logging will be stopped. Red LED will be flashing every 4 seconds and LCD screen will still show (According to the home setting) the current measuring value of temperature and humidity, but it won’t be saved in flash memory, with sampling rate at 10 seconds. If a device’s LCD is not at home screen, i.e., at alarm screen, the screen will stay up to 8 seconds, and then changes itself to home screen to show the current measurements.
The data logger XH10 can be configured to start logging in 3 different modes as mentioned below.
Immediate: The data logger will start log the data immediately when unpluging the USB.
Button: Once the user press START key for more than three seconds, the logging mode starts and, on the LCD, will be flashing. The flashing logging icon indicates the device is waiting to be started to log and it will stop flashing until the logging delay timer (DLY) is up, then the device enters the logging mode and the logging icon turns solid. At logging mode, Green LED will be flashing every 4 seconds. The measuring value is saved periodically in the flash memory according to the preset logging period.
At time: The data logger will start the logging at the specified time with the configured start and stop time.
Yes. The Data Logger Viewer can be used with Windows 10.
XH10
No, users can't calibrate the XHlogger, but they can use the “offset” function to tune the temperature or humidity.
Yes. The data logger XH10 has the option in the configuration for the device time zone.
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:
- 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
- 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
- If the download rate is high, battery life decreases
- If the alert LED blinks often, more power is used and battery life decreases
- If the logging rate is high, more power is used and the battery life decreases
- If the logger is shutdown between uses, battery life increases as the power consumption is at a minimum.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.
Yes. The XH10 logger has the removable battery. It can be easily replaceable by the user.
Yes. The XH10 logger has the removable battery. It can be easily replaceable by the user.
Sorry, external temperature sensors can not be connected with XH10.
The shutdown mode can only be entered via a device is in monitoring mode. Once the user press STOP key for more than 3 seconds while the device is at Monitoring mode, the device enters the shutdown mode. This will turn off LCD, LED, and all circuits excluding real time clock (RTC) function at the device. If the device is operating under this mode, the battery life can exceed years. Since this is the most power saving mode for the device, only RTC circuit is running and all other features will be shutdown. A user can press any key to bring the device back to monitoring mode.
Microsoft .NET Framework 4.7 or above.
Downloaded 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.
The data logger viewer software have the option to export the data to JPEG, CSV and PDF.
No. The Data logger Viewer software can be installed and used only on the Windows PC.
Yes. The user require Data Logger Viewer software to configure the XH10 data logger. The software can be freely download from the manufacturer website. The software will allow the user to configure the parameters of the device such as time zone, device name, PDF language, password, temperature unit, offset, data logging start mode, start time, start delay, stop mode, log interval, alarm.
