Re: Instrument Repair/calibration

["MGP Instruments" <jkost@mgpi.com>]

Joey,

I have performed numerous cable replacements and I have never notice a drop
in H.V or signal strength.  I performed several re-calibrations for
verification and document all of the results.  Some older equipment might
have problems but with newer electronics no noticeable change will occur,
even different cable lengths.

I hope this helps,  just document your findings.

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.
