8. For the Model 2602A/2612A/2636A, repeat the above procedure for the other channel.
Output current accuracy
Series 2600A output current accuracy 100nA and higher
Follow the steps below to verify that the Series 2600A output current accuracy is within specified
limits.
NOTE An alternate procedure for 100nA current accuracy is shown in the
1nA to 100nA Output current accuracy procedure for the Model
2635A/2636A.
1. With the power off, connect the digital multimeter to the Series 2600A output terminals, as
shown in
Figure 22-2.
2. Select the multimeter DC current measuring function.
3. Select the Model 2602A/2612A/2636A single-channel display mode.
4. Press the Series 2600A SRC key to source current, and make sure the source output is
turned on.
5. Verify output current accuracy for each of the currents for the 1uA to 1A ranges listed in
Table 22-6 (Model 2601A/2602A), or Table 22-7 (Model 2611A/2612A), or Table 22-8
(Model 2635A/2636A). For each test point:

40V 36.000V 35.9866 to 36.0134V
1. Measure range coupled to source range when simultaneously sourcing and measuring
voltage.
2. As measured by precision digital multimeter. Use closest possible value, and modify reading
limits accordingly if necessary.
