1:This is a test of the bottom of the 20V range .

2:Observe the Calibrator output for 10 minutes and verify that it remains stable within ±7.5 ppm.

3:Perform only for units that are used with a 5725A Amplifier.

4:When the TUR (Test Uncertainty Ratio) is less than 4:1, the spec is reduced to give the same Consumer Risk as a 4:1 TUR as described later in this chapter.
