Fluke 9500 Calibration
If you have a Fluke 9500 that is coming due calibration I recommend you add a 250k Ohm Calibration point to the resistance test points.. The newer scope procedures from Tektronix are adding a this test point to their verification procedures.
The 9500 does not spec this test point, so we have been working with our customers to test this point and establish the uncertainties. What we have found is the 250k Ohm measurement uses the same range as the 1M Ohm measurement. We have been successful testing this point to the same specifications as the 1M Ohm specs.
If you have any questions drop me a line.
