Ac Voltage; Ac Current; Dc Current - MAC TOOLS EM720C Notice D'instructions

4.4 AC Voltage

1. Insert the red test lead in the "INPUT" jack and the black lead in
the "COM" jack.
2. Move the rotary switch to the "V
across the circuit or load to be measured.
3. Read measured voltage on the display.
Use extra caution when measuring high voltages to
avoid electric shock or damage.
Do not attempt to measure voltages above 600V AC
to prevent injury or damage to the meter.

4.5 AC Current

1. Move the rotary switch to the "A
2. Press the trigger and insert one conductor inside the jaws. Only
clamp one conductor, multiple conductors with different current
directions will cancel out readings.
3. Read measured current and the frequency value on the LCD
display.

4.6 DC Current

1. Move the rotary switch to the "A
2. Press the trigger, open the clamp and insert one conductor inside
the jaws only clamp one conductor multiple conductors with diffe-
rent current directions will cancel out readings.
3. Read measured current on the LCD display.
