34410A Calibration Questions

I have several 34410A's and I want to calibrate them. I do not have all of the required equipment to hit the calibration points listed in the service guide. I only use the 34410A's in limited ranges (i.e. I read voltage with them, but only to 10 V.) So my question is, if I am doing something like the DCV gain calibration, I can generate and measure the input voltage for all of the inputs up to 100 V, what happens if I can't generate the 500 V input? I could care less if the voltage measurement in the 1000V range is accurate or not. If I can't generate 500 V, will it abort the calibration? The service guide says that valid gain adjustment values must be within 10% of the nominal value, is there any way around that?

Thanks.

You must calibrate at least the 10V DC, and 10Kohm ranges. Most other ranges depend on these to be calibrated correctly in order to perform to spec. Then from there on out,you can calibrate only the ranges and functions that you will need.

There is no work around that I know of to the the 10% of nominal value. For most of our products, the FW limits the input value for calibration to a fairly wide 10%.

Ok thanks. Am I thinking correctly that one can end the calibration at the "CAL SUCCEEDED" message at the end of each range? In other words, if I'm doing the DCV ranges, I can just stop at 100 V and leave the existing calibration in the meter for the 1000 V range?
