(see Figure 299).

Step 5: Connect a current source to terminals D7 and D8 (IG).

Step 6: Slowly increase the ground current until OUT2 closes and record the pickup. Verify that there is

a 50-1-IND GND target on the front-panel display. Slowly decrease the applied current until

OUT2 opens and record the dropout.

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.
