XDT User’s Manual AppendicesAppendix L: Procedure for Exchanging XDT SensorsTo exchange sensors one must know the measured low attenuation of the sensor at some low dewpointas well as the calibration adjustment value. These numbers can be found on the shippingcontainer serial number label.Through the following steps it is helpful to refer to Appendix A: Flow Diagram of XDT Set-UpState User Interface1. Power up (or reset) the XDT while holding down the MODE key, in order to enter the Set-Upstate. Make sure that the instrument in unlocked, refer to section 3.4.5.-10.2. Press the MODE key to go to the “Choose Sensor Type” mode. Make sure that the propersensor type is chosen, e.g. XT1 (for XTR-100) or XT6 (for XTR-65).3. Press the MODE key to go to the “Set Measured Attenuation @ low dewpoint” mode. Thedisplay will show the currently entered attenuation in decibels (dB), this is indicated by havingboth the °C and °F on the display. Use the UP or DOWN keys to select the value whichappears on the shipping container label. Note that this value is a negative number typically inthe range of -18.0DB to -14.0DB.4. Press the MODE key to go to the “Set low dewpoint” mode. The display will show the currentlyentered low dewpoint. Use the UP or DOWN keys to select the value which appears onthe shipping container label.5. Press the MODE key to go to the “Calibration Midrange Adjust” mode. The display willalternately show CAL and ADJ. Press the UP key once to see the entered calibration adjustmentvalue. The display will alternately show the currently entered value and the dewpoint beingmeasured, when showing the Cal Adj value the number (in the range of -2.0 to +2.0) will befollowed by a blinking “X”, and when showing the dewpoint the display will have the appropriatelegend e.g. °C. Use the UP or DOWN keys to select the value which appears on theshipping container label.6. Press the MODE key five (5) times to go to the “Lock or Unlock” mode. The display willalternately show UN and LOC. Press the DOWN key to lock the instrument. The display willalternately show only LOC.This prevents inadvertent changes.7. Press the MODE key once.8. Now the instrument has stored in it’s EEPROM, the calibration values associated with the newsensor, HOWEVER NOTE THAT IT IS STILL NOT CALIBRATED. The instrument maynow be reset.9. Perform the SpanCheck Procedure in section 3.4.4.3.1.10. Install the sensor in the sample system and measure. If for some reason the Cal Adj value mustbe re-entered or modified to improve accuracy the unit does not have to be SpanCheckedagain.55
