Compliance accuracy
Follow these steps in order to test Model 6220/6221 compliance accuracy:
1. With the power off, connect the digital multimeter (DMM) to the Model 6220/
6221 OUTPUT jack, as shown in Figure 16-3. Also connect the shorting
connector to the INTERLOCK connector (see Section 2 for interlock con-
nections).
2. Turn on the Model 6220/6221 and DMM, and allow them to warm up for one
hour before proceeding. Set the DMM to the DC volts function, and enable
auto range.
3. Set the Model 6220/6221 current output to 10mA and the compliance to
10.000V, and turn on the output. (See Section 3 for details on setting the
output current, compliance, and range.)
4. Verify that the DMM reading is within the following range: 9.97 to 10.03V.
5. Set the Model 6220/6221 compliance to 100.00V.
6. Verify that the DMM reading is within the following range: 99.8 to 100.2V.
7. Repeat steps 3 through 6 for a current output of -10mA. DMM readings will
be negative, but they should be within the same range of magnitude as in
steps 4 and 6.
8. After testing, first turn off the output, then disconnect the test equipment.
