SPECIFICATION TA300 - 1 - 310807 Fig.1 4. OPERATION 4.1. MEASURE VOLTAGE 4.1.1. Set the function switch in V /A~ position, press “SELECT” button to select Vdc or Vac measuring mode. 4.1.2. Connect the test lead and test probe across the source or circuit to be measured. 4.1.3. Read the reading. NOTE! The max. permitted voltage is 600Vac/dc rms. The meter may show an unsteady reading when the test lead and test probe are not in contact with the circuit to be measured, this is normal because the meter’s sensitivity is very high. When the test lead and test probe touch the circuit to be measured, the display will show the true reading. 4.2. MEASURING RESISTANCE 4.2.1. Set the function switch in the “ Ω“ position. 4.2.2. Connect the test lead and test probe across the circuit to be measured. 4.2.3. Read the reading. NOTE! When the measured resistance is more than 1MΩ, it will take several seconds for the reading to be steady. When the test lead and test probe are open, the display will show “OL” for overload indication. Before you measure in-circuit resistance, ensure that the power supply has been switch off and all the capacitors have been fully discharged. 4.3 TESTING DIODE 4.3.1. Set the function switch in “ ” position. 4.3.2. Press the “SELECT” button to set the meter in diode range. 4.3.3. Connect the test probe to the anode of the diode and the black test lead to the cathode of the diode. 4.3.4. Read the reading. NOTE! The display will show the approximate value of the forward-voltage drop of the diode. If you connect the test probe and test lead across the diode in the wrong direction, the display will show "OL". 4.4. TESTING FOR CONTINUITY 4.4.1. Set the function switch in " " position. 4.4.2. Press the "SELECT" button to set the meter in " " range. 4.4.3. Connect the test probe and test lead across the circuit to be measured. 4.4.4. If < about 50Ω, the buzzer will sound. 4.4.5. Read the reading. 4.5. MEASURING CAPACITANCE 4.5.1. Set the function switch in " " position. 4.5.2. Press the "SELECT" button to set the meter in capacitance range. 4.5.3. Connect the test probe and test lead across the capacitor to be measured. 4.5.4. Read the reading. NOTE! When you measure a high-voltage capacitor, it will take several seconds for reading to steady (30 seconds for 100mF range). 4.6. MEASURING DUTY CYCLE 4.6.1. Set the function switch in "DUTY" position. 4.6.2. Press the "SELECT" button to set the meter in duty cycle range. 4.6.3. Connect the test probe and test lead across the source or load to be measured. 4.6.4. Read the reading. 4.7. MEASURING FREQUENCY 4.7.1. Set the function switch in "Hz" position. 4.7.2. Press the "SELECT" button to set the meter in Hz range. 4.7.3. Connect the test probe and test lead to the signal to be measured. 4.7.4. Read the reading. 4.8. AUTO POWER-OFF 4.8.1. When idle, the meter will automatically power off and give 5 short beeps and one long beep. If you move the function switch or press “HOLD” or “SELECT”, the meter will turn on.
