Current Accuracy Tests
1. Connect the equipment as shown in Figure 2.
2. Center the UUT jaws around the single-turn #14 gauge wire.
3. Set the 5520A output as called out in Table 3. Check that the Multimeter readings are within the
specified limits in step 1 of Table 3.
4. Place the 5520A in Standby mode.
5. Connect the equipment as shown in Figure 3.
6. Center the jaws of the UUT around the 5500A coil.
7. Apply the 5520A output as called out in Table 2, steps 2 and 3. Verify that the Multimeter readings are
within the specified limits.

*To obtain the best TUR, the Fluke 189 is pre-calibrated at each step using the 5520A with LCOMP OFF. The Fluke 189
error is then algebraically added to the UUT reading. The Fluke 189 must be in a mA B function.
