7. Verify the calibrator is set to high resistance output mode.
8. Set the 2290-5 to output the first voltage test point (see Tab l e 6 ).
The 2290-5 output must be within 5 % of nominal.
9. Push OPER on the 532xA and 2290-5 to set the operate mode, if necessary, and wait for
the calibrator to stabilize.
10. Push and hold
on the DUT until it beeps (~1 second).
Wait for the DUT to finish both the + and - measurements. Record only the plus indication
on the DUT in the test record.
Note
Ignore the red X or green
. They do not indicate a pass or fail for this calibration.
11. Set:
532xA calibrator to output the next resistance test point
2290-5 to output the next voltage setting
voltage output of the DUT to the next voltage setting
See test points in Ta b l e 6 .
The 2290-5 output must be within 5 % of nominal.
12. Repeat steps 9 through 11 for all test points.
13. Set the 532xA and 2290-5 to standby mode.
