Maintenance 6

Service

4.The following tests require a Fluke 5725A Amplifier (or equivalent) to be used with the 5700A. The input level for the performance test will be set on the 5700A but will be output from the 5725A Amplifier.

Connect a cable from the Output VA HI and LO connectors of the 5725A to the l0A and COM connectors on the Fluke 45. Select the function and range on the Fluke 45 and the input level from the 5700A using the values contained in Table 6-4. The dis- play should read between the minimum and maximum readings listed in the table.
