j. Disconnect the test leads and reconnect the circuit which was
originally opened.
49 AC CURRENT MEASUREMENTS:
a. Review Safety Precautions in Paragraph 4.2.
b. Depress ACmA function switch.
c. Depress the appropriate current range switch as indicated in
Table 4-5. If the current being measured is unknown (but less
than 10A), begin with the 20 (10A) switch. Connect the red
test lead to the 10A jack and the black test lead to the COM-
MON jack.
d. Remove all power to the circuit being measured and discharge
all capacitors.
e. Connect the test leads according to Table 4-5.
f. Open the circuit in which the current is to be measured and
