AC CURRENT MEASUREMENTS
a. Set range switch to the orange colored “6/30A”.
b. Set the function switch to “AC”.
c. Connect black marked lead into “AMPS” jack, and the red marked lead into “6A”
or “30A” jack as shown in Fig. 4. (When in doubt, first select the “30A” jack).
d. Turn off power in the circuit to be measured.
e. Connect the test leads in series with the circuit to be measured (either polarity).
f. If necessary, to change the range you need to change the jack from blue colored “30A”
to the blue colored “6A”, then turn the power “ON” in circuit to be measured.
g. Read current value using the 0-15 ACA orange scale.
h. Turn off circuit power and discharge circuit capacitors, if any, before disconnecting
test leads.

Note:
The 6A and 30A connections are unfused.
Use caution when testing these high currents.
Do not leave the unit measuring 30 Amps unattended, or for
a long period of time as contact points can overheat rapidly.
