Select the multimeter DC current measuring function.
Press the Model 2430 SOURCE I key to source current, and make sure the source output
is turned on.
Verify output current accuracy for the 10μA-1A range currents listed in Table 1-5. For
each test point:
• Select the correct source range.
• Set the Model 2430 output current to the correct value.
• Verify that the multimeter reading is within the limits given in the table.
Repeat the procedure for negative output currents with the same magnitudes as those
listed in Table 1-5.
Repeat the entire procedure using the rear panel INPUT/OUTPUT jacks. Be sure to
select the rear panel jacks with the front panel TERMINALS key.
Verification of the 3A range confirms 10A pulse range accuracy.
With the power off, connect the digital multimeter and the 1Ω resistor to the Model 2430
INPUT/OUTPUT jacks, as shown in Figure 1-3.
Select the multimeter DC volts measuring function.
Press the Model 2430 SOURCE I key to source current, and make sure the source output
is turned on.
