Theodolite Calibration - Does anyone know what to do about the ingar bars?

I've just sent out our Theodolite for calibration. That's no problem-takes two days and $225 per head. But does anyone know what to do about the ingar bars? We measure up to ten feet long fictures. Can we use our CMM? If so-what do we measure it to? Sending it out takes up to three weeks and we need it. I am unclear as to the necessity of calibrating the bars.

Just to let everyone know-I sent the "invar" bars kit to Kansas (Brunson Company). They will check and send documentation for $210.
