Step 4: Prepare to monitor the 37 function operation. Operation can be verified by monitoring OUT2

(see Figure 252).

Step 5: Connect a current source and apply 0.6 Aac to terminals D1 and D2 (A-phase). Note that IA, IB,

or IC can be used for this test. Test is conducted on IA.

Step 6: Slowly decrease the A-phase current until OUT2 closes and record pickup. Verify the 37-1

target on the front-panel display. Slowly increase the applied current until OUT2 opens and
record reset.

Step 7: Repeat step 6 for the middle and high range pickup settings for your sensing input type. Record

the results.

Step 8: (Optional.) Repeat steps 1 through 7 for settings group 1, 2, and 3.

Step 9: (Optional.) Repeat steps 1 through 8 with CT Circuit 2 as the source for protection systems

equipped with two sets of CTs. In step 5, replace D1 with F1, D2 with F2, etc.
