15. Set the Model 5700A output to 19.0000 μA, and turn the output on.
16. Verify that the Model 6482 current reading is within the limits for the 20 μA range as shown in
Table
17. Repeat steps 12 through 15 for the 200 μA through 20 mA ranges.
NOTE
18. With the power off, connect the Model 5700A to the Model 6482 channel 2 INPUT triaxial
connector as shown in
19. Repeat the procedure for channel 2 (step 13 through step 17). Make sure to select channel 2
