Mainframe output current accuracy limits
With the power off, connect the digital multimeter to the Model 6430 INPUT/OUTPUT
jacks as shown in Figure 18-3. (Connect Model 6430 INPUT/OUTPUT HI to DMM
AMPS input; INPUT/OUTPUT LO to INPUT LO.)
Select the multimeter DC current measuring function.
Press the Model 6430 SOURCE I key to source current, and make sure the source out-
put is turned on.
Verify output current accuracy for the currents listed in Table 18-5. For each test point:
• Select the correct source range.
• Set the Model 6430 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 18-5.
