5-4 Performance Verification Rev. D
!
Set the DMM with
Ohms and Ohms sense
to provide a 4 wire measurement.
!
Connect it to Channel 1.
!
Measure the
input impedance
. Record it in Table 2, and compare it to the
limits.
!
Repeat the above test for all input channels.
!
Recall
xxxP002.PNL
or Set Input gain to
200 mV/div.
on all 4 Channels
!
Repeat the test for all input channels.
!
Record the measurements in Table 2, and compare the test results to the
limits in the test record.
