Before using the product for the first time, please read the instructions for use below and retain them for later reference. The original
instructions were written in the Hungarian language.
FEATURES:
• voltage measurement (600 V DC, 600 V AC) • current measurement (10 A DC) • resistance measurement (2 MΩ) • continuity test • diode test •
automatic polarity display • range excess indicator • battery status display • storing measured values
MEASURING DC VOLTAGE
1. Connect the black measuring cord to the COM socket and the red cord to the VΩmA socket.
2. Set the turn switch to the desired V value and the instrument is ready to take measurements. If the value of the voltage
to be measured is unknown always select the largest value using the turn switch first, and decrease the range as required.
3. You can now connect the cords to the circuit to be measured.
4. Connect the power to the circuit to be measured, and the display will show the measured DC voltage. If you connected
the measuring cords inversely, a minus sign indicating negative polarity appears on the left.
MEASURING AC VOLTAGE
1. Connect the black measuring cord to the COM socket and the red cord to the VΩmA socket.
2. Set the turn switch to the desired V ~ value and the instrument is ready to take measurements. If the value
of the AC voltage to be measured is unknown always select the largest value using the turn switch first, and decrease the range as required.
3. You can now connect the cords to the circuit to be measured.
4. Connect the circuit to be measured to the power, 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 VΩmA socket.
2. If the value of the DC current to be measured is unknown, set the turn switch to 10 A and connect the red measuring cord to the 10 ADC socket. (You must do the same if the current to
be measured is between 200 mA and 10 A.)
3. Now connect the instrument to the circuit which is still switched off in serial connection.
4. Connect the power to 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 on the left.
5. Once you have made sure that the current to be measured is below 200mA, you can plug the red cord into the socket labeled „200 mA max" after disconnecting the power from the
measured circuit. 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.
MEASURING RESISTANCE
1. Connect the black measuring cord to the COM socket and the red cord to the VΩmA socket.
2. If the value of the resistance to be measured is not known, set the turn switch to 2 MΩ. The exact value of the resistance can be determined by gradually progressing towards
smaller measurement ranges.
3. If the resistor is not removed from the circuitry, you must disconnect the power from the circuit and discharge all capacitors before starting to take the measurement.
4. You can now connect the cords to the part to be measured.
5. You can read the current measurement from the display.
