Thanks for the heads up , so basically 0.001% or better? that is a lot of money there in those resistors, I have tried most of the ranges using 0.1% resistors (except for the 1M and 10M using 1%) and all resistors fell within tolerance
Sorry I wrongly interpreted your previous question about what tolerance of resistors are best suited to verify the meters accuracy and I'm probably not the best person to advise in that regard but it looks like Vgkid had it nicely covered.
Also your meter sounds like it's pretty well spot on going by your last post so you may not need to do much in relation to the calibration process at all, have you checked the calibration status by pressing the cal button and then the log key?, and only do this if you are content to verify whether the unit is using true or default values as described in both the manual and the cheat sheet. Do not press the store key whislt the cal button is depressed or you will load the default values if it hasn't already been done.
Lastly I posted back at reply #9 the brochure for the Arcwin software if you need it, there might be some handy information on its operation and I did amend the cheat sheet after first posting it so watch out for that as well as it is not finalised as yet.
