5. Verify output current accuracy for each of the currents for the 1uA to 1A ranges listed in
Table 15-6

7. Turn the output off, and change connections as shown in
connections to the 0.5Ω resistor as shown).
8. Select the DMM DC volts function.
9. Repeat steps 4 through 7 for the 3A range (Model 2601/2602) or 1.5A range (Model 2611/
2612/2635/2636). Calculate the current from the DMM voltage reading and characterized
0.5Ω resistance value: I=V/R.
10. For the Model 2602/2612/2636, repeat the above procedure for the other channel.

Select the correct source range.
Set the Series 2600 output current to the correct value.
Verify that the multimeter reading is within the limits given in the table.
