To measure current, you must break the circuit and connect
the leads in series with the circuit.
WARNING: DO NOT APPLY VOLTAGE TO THE TEST
LEADS WHEN THE RANGE SWITCH IS IN THE CURRENT
1. Set the range switch to one of the DCA positions. Always
start at the highest range and work down.
2. For 10A measurement: Plug the red lead into@)DC 10A

4. Connect probes to the circuit in series. (black lead to the
negative side and the red lead to the positive side).
5. Apply voltage to the circuit under test.
6. Set the range and the range doubler switches as required
to obtain a meter reading in the upper 1/2 or 1/3rd of the
scale.
7, Read the current on the black DC scales.
If the range doubler switch is in the V-A/2 position, be sure
to divide the range switch setting by 2 and read the
appropriate scale.
