Performance Test Procedure
To test each of the Meter’s functions and operating ranges, do the following:
1. Connect the source to the Meter’s VΩ and COM input jacks.
2. Referring to Table 2, put the Meter in the desired function and range for each test.
3. Apply the indicated output from the source.
4. When using the amp function on the 5520A, make sure LCOMP on the 5520A is ON.
5. The reading on the Meter display should be within the low and high limits shown in the table.
6. Repeat steps 1-4 for each function and range in Table 2.
If the Meter fails to perform within the low-high range indicated for each test in Table 2, the Meter needs
to be calibrated and adjusted, or requires some repair.
