Output current accuracy
Follow the steps below to verify that the Series 2600 output current accuracy is
within specified limits.
1. With the power off, connect the digital multimeter to the Series 2600 output
terminals, as shown in
Figure 15-2.
2. Select the multimeter DC current measuring function.
3. Select the Model 2602/2612 single-channel display mode.
4. Press the Series 2600 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 100nA to 1A
ranges listed in
Table 15-6 (Model 2601/2602) or Table 15-7 (Model 2611/
2612). For each test point:
• 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.
6. Repeat the procedure for negative output currents with the same
magnitudes as those listed in
Table 15-6 or Table 15-7.
7. Turn the output off, and change connections as shown in Figure 15-3 (use
4-wire 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). Calculate the current from the DMM voltage
reading and characterized 0.5Ω resistance value: I=V/R.
10. For the Model 2602/2612, repeat the above procedure for the other
channel.
