DC Current
The dc current performance test verifies the accuracy of the current output from the front
panel of the Product. Use the 8508A and the precision shunt to measure the Product
output. Divide the voltage indication from the 8508A by the 742A-1 actual value to
determine the current output. Verify the measurements shown in Table 5. See Figure 2
for connections.
