1-8 Performance Verification
proper polarity (SOURCE + to INPUT HI; SOURCE - to INPUT LO). Also be sure to
use 4-wire connections to the resistor terminals.

2. Select the multimeter DC voltage measuring function, and enable auto-ranging.
3. Turn on the Model 2303 output.
4. Verify compliance current accuracy for the currents listed in Table 1-4. For each test
point:
• Set the Model 2303 output voltage to 9V, and set the compliance current to the value
being tested.
• Note and record the digital multimeter voltage reading.
• Calculate the current from the voltage reading and actual 1Ω resistor value: I = V/R
• Verify that the current is within the limits given in the table.
