Output verification test
This test verifies that the output functions (constant voltage and constant 
current) are within specifications. Note that the measurement values over 
the remote interface should be identical to those displayed on the front 
panel.
CV programming and readback accuracy
This test verifies that the constant voltage programming and readback 
accuracy are within published specifications.
1 Turn off the instrument and connect a digital multimeter between the 
front panel   (red) and   (black) output terminals (see Figure 5- 5 on 
page 143).
2 Turn on the instrument. Press Voltage to select the constant voltage 
mode. Ensure that the S1 (30 V/1 A) range is selected (the S1 
annunciator is illuminated). Press Shift > Range again if it is not.
3 Output each value in the order shown below. Record the output voltage 
reading on the digital multimeter. Compare the measurement results to 
the appropriate test limits shown in Table 5- 9.
You should consider programming the U3606A over the remote interface 
for this test to avoid round off errors. See the U3606A Programmer’s 
Reference for more information on remote interface programming.
