Task- create a internal calibration procedure for multiple DMM's for internal use in a ISO 9001 mechanical development lab.
Problem- little time, no budget to send them out, and about 8 to 10 different models.
Ok- I am hoping everyone can chime in and tell me just how bad of an idea this is with suggestions. We have DMM's ranging form old Fluke 37's to Agilent/HP 34401A & 3468B, to Keithley 2000's. We used to use our meters (Qty. 73) routinely for all sorts of measurments. Now we use only about four meters, and 99% of that time they are only measuring 0 to 10 DC Volts. I need to create a calibration procedure using a Fluke 5500A as the reference standard. Does it make sense to create one generic procedure that only verifies partial DMM capability (limited calibration)? We would only ever need to measure, DC Volts, DC Amps, Ohms, and Freq. at 1V AC. Instead of doing an indepth calibration, only check the few mesurment ranges we might use and have a blanket tolerance (Error in percent of reading).
In short:
Multiple Meter Models
One Procedure
Limited Calibration
Blanket tolerance (% of reading)
Thanks for your time.
