1-14 Performance Verification
Output current accuracy
Follow the steps below to verify that Model 2410 output current accuracy is within specified
limits. The test involves setting the output current to each full-range value and measuring the
currents with a precision digital multimeter.
1. With the power off, connect the digital multimeter to the Model 2410 INPUT/OUTPUT
jac
ks as shown in Figure 1-2.
2. Select the multimeter DC current measuring function.
3. Press the Model 2410 SOURCE I key to source current, and make sure the source output
is tu
rned
on.
4. Verify output current accuracy for each of the currents listed in Table 1-4. For each
test
poin
t:
• Select the correct source range.
• Set the Model 2410 output current to the correct value.
• Verify that the multimeter reading is within the limits given in the table.
5. Repeat the procedure for negative output currents with the same magnitudes as those
listed in
Table 1-4.
6. Repeat the entire procedure using the rear panel INPUT/OUTPUT jacks. Be sure to
select th
e rear p
anel jacks with the front panel TERMINALS key.
