Over-Temperature Protection; Testing And Calibration - Fluke Datapaq TP3 User Manual

Over-temperature Protection

The logger and the Insight software work together to reduce the likelihood of
damage occurring due to the logger's internal temperature being too high. (For the
logger's operating-temperature range, see p. 13.)
• Insight can be instructed to show a warning message if a reset is
attempted (p. 41), or to prevent a reset, while the logger is above a
specified temperature (default 45ºC/113ºF); see p. 53.
• If logging is started without resetting the logger using Insight (i.e. by simply
pressing the start button and thus using the previous reset options; see
p. 47), the logger will not start logging if its internal temperature is above
45ºC/113ºF. The logger-status red LED will show 2 quick flashes every second.
• If the logger's internal temperature exceeds 75ºC/167ºF (when fitted with
NiMH or alkaline battery) or 115ºC/239ºF (when fitted with lithium battery),
it shuts down, preserving data already collected. When the data is
downloaded, Insight will give a warning that this has happened.
The logger records its internal temperature during a profile run. For access to this
To check the logger's current internal temperature when connected to a PC running
Insight, select Logger > Setup and click 'Diagnostic' (p. 39). The temperature is

Testing and Calibration

It is recommended that the logger is tested and calibrated by Fluke Process
Instruments at least once a year. The calibration procedure comprises:
• Inspection of the logger, externally and internally.
• Battery- and charge-testing.
• Heat-cycle test of up to 14 hours in the ovens of Fluke Process Instruments.
• 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 UKAS or NIST calibration
standards.
To calibrate your logger, please return it to the Service Department at Fluke
Process Instruments (see p. 63).
For full certification and traceability, calibration data is stored in each logger for
instant access by Fluke Process Instruments engineers. To print a calibration
certi ficate for a logger, in Insight select File > Print Calibration Certificate (NB not
available with all Insight products), and then choose whether to print a certificate for:
