. The Product shows
the actual measured current.
6. Set the function on the Product to dc current and set the value to 0.0 mA.
7. On the 5522A, push the ON button. The Product reads approximately 0.0 mA.
8. Push the
Write
softkey to save the new value for the 0.3 mA current range, point 0.0 mA. To
leave the original value, push the
Exit
softkey. The Product ignores the measured current
and returns to the list of current ranges.
9. Select the second position of the 300
μ
A range,
Range 300

.
10. Set the 5522A to 0.25 mA. The Product reads approximately 0.25 mA.
11. Use the cursor buttons or rotary knob to get a measured value of 0.025 00
μ
A.
12. Push the
Write
softkey to save the new value for the 0.3 mA current range. To leave the
original calibration constant, push the
Exit
softkey. The Product ignores the measured
current and returns to list of current ranges.
13. Use the same process to go through next two ranges.
14. At the end of the adjustment process, push the
Exit
softkey until the display shows the Low
resistance source function.
This completes this part of the adjustment.
