INSTRUCTIONS
Shortly press MODE button to switch function between DC voltage, signal frequency measurement, resistance and DC current. Connect the red clip to positive of battery and black clip to negative of battery. Auxiliary ground connector is used to connect with the negative of testing object when it is necessary.
DC VOLTAGE MEASUREMENT Shortly press MODE button to switch function to DC voltage measurement. Connect the testing probe and auxiliary ground connector to the two polarity of the testing object. (CAUTION: DO NOT press the POWER PROVIDING SWITCH during the measurement.) Read the voltage value from the screen.
SIGNAL FREQUENCY and MAX / MIN VOLTAGE MEASUREMENT Shortly press MODE button to switch function to signal frequency measurement. Connect the auxiliary ground connector to the negative or ground, and probe to the positive or the testing target. Read the frequency value from the screen. Long press MODE button for 3s to switch to MAX voltage value display. Long press MODE button for 3s again to switch to MIN voltage value display. Long press MODE button for 3s again to switch to frequency measurement.
RESISTANCE MEASUREMENT In order to prevent electrical hazard, please disconnect the power connection and make sure all capacitor has been discharged before the measurement. Shortly press MODE button to switch the function to resistance measurement. Connect the testing probe and auxiliary ground connector to the two side of the resistor and read the value from the screen. Continuity Test: If the resistance is less than 30 ohms, the buzzer will buzz.
DC CURRENT MEASUREMENT There are two methods to measure the current: METHOD 1 Providing Current to External Shortly press MODE button to switch the function to DC current measurement. Connect the testing probe to the positive of testing load and auxiliary ground connector to the negative of testing load. Press the POWER PROVEDING SWITCH forward and read value from the screen.
METHOD 2 Connect the testing probe to the negative of testing load and auxiliary ground connector to the ground of the circuit. Press the POWER PROVIDING SWITCH backward and read the value from the screen.
TESTING POWER PROVIDING This function can be activated anytime when the POWER PROVIDING SWITCH has been pressed. Press POWER PROVIDING SWITCH forward, the positive voltage will be sent to the testing probe and positive polarity indicator will light up (Red Color). Press POWER PROVIDING SWITCH backward, the negative voltage will be sent to the testing probe and negative polarity indicator will light up (Green Color). The providing voltage value will depend on the supply voltage level. For example, is a 12V battery has used as the supply voltage, the providing voltage will be 12V.
CAUTION: During the power providing, if the short circuit protection has activated, the PPTC fuse will jump off, and it will self-recover within about 60 seconds. Please do not touch the testing probe when short circuit protection is activated because high temperature generally comes with short circuit.
