The lock feature was built into the TI-25PX for the purpose of locking the operators 
out of editing any of the gauge settings, for purposes of consistency between operators. 
When the lock feature is enabled, the gauge calibration functionality cannot be altered, 
as well as any of the individual features in the gauge. The only keys that are always 
unlocked are the power and probe zero keys, as these must remain unlocked for 
measurement functionality.
