    12. File the calibration data. * If your probe has another diameter than those supplied, use an insert adapter, drilled to the correct diameter. A more thorough description of the above points is found in the chapter “How to use the TC65M/15M calibrator”.

    Never remove the cover of the calibrator unless you are a qualified service technician. High voltages and temperatures will be exposed. Always ensure that the air inlet in the bottom of the TC65M/15M is free and not clogged by dust. Ensure that the fan is running. If not, do not use the TC65M/15M as it will overheat and create a potential danger.

  • Page 6: Why Calibrate

    TC65M/15M User’s manual Why calibrate? The definition of the term “calibration” is: To determine the difference between the object being calibrated with a known reference and knowing the uncertainty in the process. Adjusting the calibrated object in order to remove the error is of secondary importance as long as the error is either within acceptable limits or the error is used to calculate the real value.

  • Page 7: How Often Do I Calibrate

    TC65M/15M User’s manual The whole chain of elements involved in the calibration process creates errors in the final reading. In this matters errors are expressed as uncertainty. Take the following elements into account when considering the total uncertainty: · Temperature drift in the calibrator ·...

    1 to 2 cm from the bottom of the well. TC65M/15M is calibrated with a 6mm PRT reference probe placed at the bottom of the insert...
  • Page 9 TC65M/15M User’s manual Also take into consideration the load the calibration object will employ to the well. A large and heavy probe will extract more heat from the well and change the gradient lines differently compared with a small and light probe.
  • Page 10 The display will in this case show “E40” and a new set point must be selected before continuing. 11. Test of thermostats. The TC65M/125M have a built-in test functions for thermostats. Connect the alligator clips to the calibrators input function. Please pay attention to the fact that thermostats react slowly to temperature changes.

  • Page 11: Maintenance

    This also applies to your calibra- tion objects. TC65M/15M is a dry well calibrator. Do not use oil in the well holes. There are no user serviceable parts inside the calibrator. However, there is a 15A main fuse inside that may brake due to internal failure.

  • Page 12: Trouble Shooting

    TC65M/15M User’s manual Trouble shooting Unstability may occur if the mains supply voltage varies. This is sometimes the case if the stability seems to be erratic for no reason. Warranty Scan-Sense standard warranty conditions.

  • Page 13: Appendix

    TC65M/15M has been calibrated. · In the “Measuring report” table there is a column “TC65M/15M correction” that may be filled in if you have a calibration certificate for your TC65M/15M stating measuring errors. By calculating the “TC65M/15M real value” you will achieve better accuracy.
  • Page 14 Remarks: · “Test object deviation” is calculated by subtracting “TC65M/15M real value” from “Test object reading”. · The value “Test object deviation” tells how much the reading of the test object is off. A positive figure tells how much the reading is above the actual value.
