It also has a continuity function and can be used as a logical tester. It is ideal for work and home use as well. tHe front panel 1. display 3½ digits, 7 segments, large LCD (27 × 60 mm) 2. Function and range switch This switch selects the functions and the desired range. It also turns the device on. To prolong battery life set it to OFF when you are not using the device. 3. “5a” banana (wire) connector Connect the red (positive) measuring wire into this connector to measure 10A current. 4. “VΩma” banana connector Connect the red measuring wire into this connector to measure every kind of voltage, resistance and current (except for 5A) 5. “COm” banana connector Connect the black (negative) measuring wire here. tecHnical data dC voltage range resolution accuracy 200mV 100uV ±0.5% +3D 2000mV 1mV ±1.0% +5D 20V 10mV 200V 100mV 300V 1V ±1.2% +5D Overload protection 220V RMS AC at 200mV range, és 300V DC or 300V RMS on every range aC voltage range resolution accuracy 200V 100mV ±1.2% +10D 300V 1V Reaction Average, calibrated on the RMS of the sine wave Frequency range 45Hz ~ 450Hz Overload protection 300V DC or 300V RMS on every range Continuity test with audio signal range description A built-in beeper signals if the resistance is below 30±20Ω Overload protection 15 seconds maximum 220V RMS 300 300 5 300 300V~max - 1 2 3 4 5 www.netker8.hu User Manual EN dC current range resolution accuracy 2000μA 1μA ±1.8% +2D 20mA 10μA 200mA 100μA ±2% +2D 5A 10mA ±2% +10D Overload protection 500mA 500V fuse (5A 500V) Measuring voltage fallback 200mV resistance range resolution accuracy 200Ω 100mΩ ±1.0% +10D 2000Ω 1Ω ±1.0% +2D 20KΩ 10Ω ±1.0% +2D 200KΩ 100Ω ±1.0% 2D 2000KΩ 1KΩ ±1.0% +2D Max. open circuit voltage 3.0V Overload protection 15 seconds maximum 220V RMS operation Warning To avoid electric shock and damage to the device do not measure voltage exceeding 300V! Always verify the intactness and insulation of the measuring wires, connectors and other units before measuring! 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 •� Connect the red measuring wire to the “VΩmA” connector and the black one to the “COM” connector. •� Set the RANGE switch to the desired OHM position. •� Connect the measuring wires to the circuit. •� Read the resistance value from the screen. diode measuring •� Connect the red measuring wire to the “VΩmA” connector and the black one to the “COM” connector. •� Set the RANGE switch to the “ ” position. •� Connect the red measuring wire to the anode of the measured diode and the black one to the cathode. •� The opening voltage dropback is shown on www.netker8.hu
