Performance Tests
The following performance tests verify the complete operation of the Current Clamp and checks the
accuracy of each function against the Clamp's specifications. If the Current Clamp fails any part of the
test, calibration adjustment and/or repair is indicated.
In the performance tests, the Current Clamp is referred to as the unit under test (UUT).
Required test equipment is defined in Table 2.

1. Connect the equipment as shown in Figure 2.
2. Center the UUT jaws around the 5500A/Coil windings.
3. Set the UUT range and 5520A output as called out in Table 3. Check that the Multimeter readings are
within the specified limits in Table 3.

To avoid damaging the Current Clamp, do not use abrasives or solvents to
clean the clamp.
Open the jaws and wipe the magnetic pole pieces with a lightly oiled cloth. Do
not allow rust or corrosion to form on the magnetic core ends.
To avoid electric shock or injury, do not perform the performance tests or
calibration procedures unless you are qualified to do so.
