7. nal information source provided by menu option 1 called Ref It is important to understand the significance and objective of this option before using it The Ref option can be engaged by pressing FUNCTION 1 Firstly the initial calibration procedure will compensate for differences between your shop environment and the factory environment where MAG ic Probe was calibrated The problem is that after this calibration your hand may heat the probe causing a small drift in value This is the reason for the 2nd calibration as described above To assist in this 2nd calibration the Ref option can be used BEFORE performing the 2nd Calibration invoke the Ref option The Ref reference option shows a value normally a negative value for example 53 This value represents a difference measured in the conditions of your environment to the factory environment where MAG ic Probe was calibrated If this value is negative as in the example 53 hold the probe in your fingers as described above The Ref value should start to increase and the zero 0 point is where the probe temperature conditions are similar to the factory calibration conditions When the Ref value is approaching the 0 mark return to the menu and perform the 2nd calibration as described above Please note that you do not have to be overly fussy about this setting as even a difference count of 300 represents well under 0 1mm deviation 33 Press FUNCTION USB Serial Connection MAG ic Pr
