2 2 Model : OPERATING MANUAL

3 Overview This Operating Manual covers information on safety and cautions. Please read the relevant information carefully and observe all the Warnings and Notes strictly. Warning To avoid electric shock or personal injury, read the ìsafety Informationî and ìrules for Safety Operationî carefully before using the Meter. Digital Inductance Capacitance Meter Model (hereafter referred to as ìthe Meterî) is a 3 1/2 digits with steady operations, fashionable design and highly reliable hand-held measuring instrument. The Model will measure capacitance, inductance, resistance, transistor hfe and test diodes. It will also test continuity with an audible buzzer. 3

4 Inspection Open the package case and take out the Meter. Check the following items carefully to see if any items are missing or damaged. Item Description Qty Operating Manual Test Clip 9V Alkaline Battery (NEDA1604, 6F22 1 piece or 006P) (installed) 1 piece 1 pair In the event you find any items missing or damaged, please contact your dealer immediately. Safety Information This Meter complies with the standards EMC EN Use the Meter only as specified in this operating manual, otherwise the protection provided by the Meter may be impaired. In this manual, a Warning identifies conditions and actions that pose hazards to the user, and may damage the Meter or the equipment under test. A Note identifies the information that user should pay attention to. International electrical symbols used on the Meter and in this Operating Manual are explained on page 7. 4

13 (figure 4) Warning To avoid damage to the Meter or to the devices under test, disconnect circuit power and discharge all the high-voltage capacitors before measuring diodes and continuity. Testing Diodes Use the diode test to check diodes, transistors, and other semiconductor 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 500mV and 800mV. To test a diode out of a circuit, connect the Meter as follows: Insert the red test clip into the terminal and the black test clip into the COM terminal. 1. Set the rotary switch to. For forward voltage drop readings on any semiconductor 2. component, place the red test clip on the componentís 3. anode and place the black test clip on the componentís cathode. The display shows the diode forward voltage dropís nearest value. 13
