MeasuriNG aC voLtaGe
1. Connect the black measuring cord to the COM socket and the red cord to the V
Ω
F socket.
2. Set the dial to AC V.
3. You can now connect the cords to the circuit to be measured.
4. Power up the circuit to be measured, and you can read the measured AC voltage from the display.

MeasuriNG DC CurreNt
1. Connect the black measuring cord to the COM socket and the red cord to the A socket. If the value to be measured is larger than 300 mA or unknown, only
connect the red wire to the A socket.
2. Select the A function using the dial.
3. Now connect the instrument to the circuit (which is still switched off) in serial connection.
4. Power up the circuit to be measured, and the display will show the measured DC current. If you connected the measuring cords inversely, a minus sign
indicating negative polarity appears.
5. Once you have made sure that the current to be measured is below 300 mA, you can plug the red cord into the socket labeled mA after disconnecting the
power from the measured circuit. Then select the mA range using the dial. If you need to change the selected function or measurement range while taking
measurements, only do so after disconnecting the measuring cords out of precaution.

1. Connect the black measuring cord to the COM socket and the red cord to the V
Ω
F socket.
2. Select the

function using the dial.
3. If the resistor is not removed from the circuit, you must power off the circuit and discharge all capacitors.
4. You can now connect the cords to the part to be measured.
5. You can read the measured resistance from the display. The displayed value needs a few seconds to stabilize if you are measuring a resistor above 3.26 M
