I made it through the DC Cal steps this evening and I was reading about the Ohms calibration.
What resistance standards are needed? 10000 ohms and 1000 ohms? 4 wire or 2?

You have to link the amplifier to your DC standard to have the stability needed. > But still, what frequency? 60 Hz? 1 kHz? The 'basic' calibration is usually performed at 400Hz. With check at higher frequencies (40KHz and 400KHz for the 7081) to know if it's still properly compensated.
