5. Verify the calibrator is set to 2-wire, low-resistance output mode.
6. Turn the rotary switch on the DUT to .
7. Push
to select Diode mode.
8. Push OPER on the 532xA to set the operate mode, if necessary, and wait for the calibrator
to stabilize.
9. Momentarily push
on the DUT.
Wait for the DUT to complete its measurement.
10. Momentarily push
on the DUT to stop continuous measurements made by the DUT.
Record the V
DIODE
on the DUT and the maximum current value indication on the 532xA (I
D
)
in the test record. Multiply the I
D
value (in Amps) by the resistance output by the 532xA
calibrator (in Ohms) and use this as the reference voltage value to compare V
DIODE
.
Note
Ignore the red X or green
. They do not indicate a pass or fail for this calibration.
11. Set the 532xA calibrator to output the next resistance test point (see Ta b l e 9 ).
12. Repeat steps 8 through 11 for all test points.
13. Set the 532xA calibrator to standby mode.
