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 148 ).
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 .
N O T E
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.
