and measure range
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.

Follow the steps below to verify that the Series 2600 output current accuracy is within specified
limits.
NOTE
1. With the power off, connect the digital multimeter to the Series 2600 output terminals, as
shown in
2. Select the multimeter DC current measuring function.
3. Select the Model 2602/2612/2636 single-channel display mode.
4. Press the Series 2600 SRC key to source current, and make sure the source output is
turned on.
