Note
[1]
: The AC filter is set to "Slow".

: Q marks the optional quick test points.
3. The AC current gain test procedures
(1) Make sure you have carefully read the "Test Conditions".
(2) Connect the input terminals of the multimeter with the calibrator.
(3) Test the ranges specified in Table 2-4. Set the AC filter to "Slow" and turn off all the math
operations.
(4) Input the signals specified in Table 2-4 using the calibrator and compare the test results
with the limits in the table (make sure the output of the calibrator is built adequately).
