OVEN TRACKER XL2 Logger Specifications and Operation 27
Thus, a hardware reset can also be used as a way of quickly restoring the
default data-collection parameters without connecting the logger to a PC.
Unlike a normal reset, a hardware reset will preserve in memory all data
already collected – it will not be deleted.
To perform a hardware reset:
1. Remove the Transducer Interface or Dual Interface Block, if attached.
2. Locate the small hole housing the reset button in the mating surface of the
MemoryPaq (p. 22), and press in briefly with a pointed object (e.g. a pen).
3. The red logger-status LED (p. 20) will flash five times to confirm reset.
Testing and Calibration
It is recommended that the logger is tested and calibrated by Datapaq at least
once a year. The Datapaq calibration procedure comprises:
• Inspection of the logger, externally and internally.
• Battery- and charge-testing.
• Heat-cycle test of up to 14 hrs in Datapaq’s own ovens.
• Stability testing, using a stable temperature source and varying ambient
temperatures.
• Calibration and updating of the logger’s firmware.
• Issue of certificate, which can be traced back to national calibration
standards.
No other company can offer this degree of in-depth testing as well as a full
calibration service. To calibrate your logger, please return it to the Service
Department at Datapaq (see title page for contact details).
For full certification and traceability, calibration data is stored in each
Transducer Interface for instant access by Datapaq engineers. To print a
calibration certificate for a Transducer Interface, select File > Print
Calibration Certificate and make the appropriate selection in the dialog in
order to print a certificate either for:
• The Transducer Interface which was used to create the currently displayed
paqfile (temperature profile). or
• The Transducer Interface which is currently connected to the PC (via the
MemoryPaq).
For processes of testing your logger’s operation with thermocouples
attached, see p. 43.
Store the logger in a dry, dust-free environment.
