The Meter Structure (See Figure 1) To test for continuity, connect the Meter as below: 1. Insert the red test lead into the HzV terminal and the black test lead into the COM terminal. 2. Set the rotary switch to and press BLUE button to select measurement mode. 3. The buzzer sounds if the resistance of a circuit under test is less than 100 . Note The LCD displays indicating the circuit being tested is open. When continuity testing has been completed,disconnect the connection between the testing lead and the circuit under test. Testing Diodes (See Figure 6) Figure 1 Measurement Operation Select A. Measuring AC & DC Voltage The table below offers information about positions around the red black rotary switch. Warning To avoid harm to you or damage to the Meter from electric shock, please do not attempt to measure voltages higher than 1000V / 750V rms although readings may be obtained. AC Voltage Measurement (See Figure 3) Figure 6 Use the diode test to check diodes, transistors, and other semicon -ductor devices. The diode test sends a current through the semiconductor junction, and then measures the voltage drop across the junction. A good silicon junction drops between Select 0.5V and 0.8V. To test a diode out of a circuit, connect the Meter as follows: 1. Insert the red test lead into the HzV terminal and the black Red Black test lead into the COM terminal. 2. Set the rotary switch to and press BLUE button to Display Symbols (See Figure 2) select measurement mode. 2 3 4 5 6 7 Figure 3 3. For forward voltage drop readings on any semiconductor component, place the red test lead on the component s anode Overview
