dC and aC voltage measuring
Connect the red measuring wire to the "VΩmA"
•
connector and the black one to the "COM"
connector.
Set the function and range switch to the
•
desired voltage position. If the voltage is
unknown, set the switch to the highest
available range, connect the wires to the
device and the circuit and reduce the range
until the value shown is correct.
dC current measuring
Connect the red measuring wire to the "VΩmA"
•
connector and the black one to the "COM"
connector. (For measuring current between
200mA and 5A connect the red wire into the
"5A" connector).
Set the RANGE switch to the desired DCA
•
position
Open the measured circuit and connect to it
•
serially.
Read the current value from the screen.
•
The "5A" function is designed for limited time
•
use only. The measuring wire should only be
connected to the circuit for the maximum
of 15 seconds and allow a few seconds in
between measurements.
resistance measuring

connector and the black one to the "COM"
connector.
Set the RANGE switch to the desired OHM
