Before you begin the calibration process e Place the Validator in a location with stable and even temperature not exposed to any local heat sources i e close to a sterilizer an open door causing a draft etc e To provide maximum accuracy during the calibration process power up the Validator and let it run for approximately 30 minutes in the operating environment where calibration is to be performed in order for the Validator to acclimate to the ambient temperature e Since transient environmental temperature will cause thermal measurements to change specifies that the Validator system be allowed to stabilize for at least 30 minutes for every 10 C change in temperature For example if you move the Validator from a 25 C environment to a 40 C degree environment it should be allowed to run for 45 minutes before use e Place the thermocouples and IRTD into the LTR making sure to use the well inserts to insert the thermocouples The LTR provides the stable temperature required for sensor calibration The IRTD a self contained precision measurement standard that provides data directly to the Validator accurately measures the temperature of the LTR The IRTD provides a traceable standard that is used to correct the temperature readings of your thermocouples For more detailed information on the hardware connections and the sensor calibration process refer to the Kaye Validator User s Guide Kaye LTR 25 140 and LTR 40 140 User s Ma
