Re: Instrument Repair/calibration




     Seems to me that it wouldn't change the response much.  However, why 
     not just verify performance by using the dedicated check source.  
     Document that this was the method used to ensure proper (not changed) 
     operation and move on.

Does changing a the cable on a portable GM (such as a Ludlum model 3) require 
the instrument to be recalibrated.  I know that the regs. state annual 
calibration and calibration after repair, but an exception is given for battery 
changes, but does changing the cable connecting the probe rank as a repair for 
this purpose?  It doesn't seem to me that it would significantly change the 
instruments response.
     
Thanks and Happy Holidays
