: The AC filter is set to "Slow".
Note
[2]
: For continuous currents greater than DC 7A or AC RMS 7A, close the circuit for 30 seconds and then open the
circuit for 30 seconds.
Note
[3]
: Q marks the optional quick test points.
4. The frequency 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) Select the range according to Table 2-5 and turn off all the math operations.
(4) Input the signals specified in Table 2-5 using the calibrator and compare the test results
with the limits in the table (make sure the output of the calibrator is built adequately).

5. The capacitance gain test procedures
(1) Make sure you have carefully read the "Test Conditions".
(2) Switch to the capacitance measurement function and select a range listed in Table 2-6.
(3) Connect one end of the shielded cable to the input terminal of the multimeter and leave the
other end free; then, execute "REL" operation.
(4) Connect the other end of the shielded cable to the calibrator.
(5) Input the signals specified in Table 2-6 using the calibrator and compare the test results
with the limits in the table (make sure the output of the calibrator is built adequately).
(6) Repeat steps (2), (3), (4) and (5) to finish the test.
