Need help on TEK 2445 calibration
|
Help.
Repaired one of my 2445's.? Need to go through Calibration.
Went through it other times in past but don't remember this.
My calibrator sq wave is not 0.4 usec wide ... it is 0.2 usec
wide.
It is not 500 mV as stated in the calibrations procedures in three
of my manuals, including 2445A/2455A manual.
It is 200 mV.
By the way, one of my other 2445's is exactly the same as the
repaired one.?? My third one is in pieces so can't check it.
SO.... calibrating to the wrong level??????? How do I change it if
it is wrong?? Or in Cal 1, do I just hit Coupling UP and go on??
Any help here??
Thanks,
Bob
