With the power off, connect the digital multimeter (DMM) to the Model 6220/
6221 OUTPUT jack, as shown in
connector to the INTERLOCK connector (see Section 2 for interlock con-
nections).
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.
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.)
Verify that the DMM reading is within the following range: 9.97 to 10.03V.
Set the Model 6220/6221 compliance to 100.00V.
Verify that the DMM reading is within the following range: 99.8 to 100.2V.
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.
After testing, first turn off the output, then disconnect the test equipment.
