SAFETY INFORMATION WARNING: To avoid possible electric shock or personal injury, and to avoid possible damage to the Meter or to the equipment under test, adhere to the following rules: 1. Before using the Meter inspect the case. Do not use the Meter if it is damaged or the case (or part of the case) is removed. Look for cracks or missing plastic. Pay attention to the insulation around the connectors. 2. Inspect the test leads for damaged insulation or exposed metal. Check the test leads for continuity. 3. Do not apply more than the rated voltage, as marked on the Meter, between the terminals or between any terminal and grounding. 4. The rotary switch should be placed in the right position and no any changeover of range shall be made during measurement is conducted to prevent damage of the Meter. 5. When the Meter working at an effective voltage over 60V in DC or 30V rms in AC, special care should be taken for there is danger of electric shock. 6. Use the proper terminals, function, and range for your measurements. 7. Do not use or store the Meter in an environment of high temperature, humidity, explosive, inflammable and strong magnetic field. The performance of the Meter may deteriorate after dampened. 8. When using the test leads, keep your fingers behind the finger guards. 9. Replace the battery as soon as the battery indicator appears. With a low battery, the Meter might produce false readings that can lead to electric shock and personal injury. 10. Remove the connection between the testing leads and the circuit being tested, and turn the Meter power off before opening the Meter case. 11. When servicing the Meter, use only the same model number or identical electrical specifications replacement parts. 12. The internal circuit of the Meter shall not be altered at will to avoid damage of the Meter and any accident. 13. Soft cloth and mild detergent should be used to clean the surface of the Meter when servicing. No abrasive and solvent should be used to prevent the surface of the Meter from corrosion, damage and accident. 14. The Meter is suitable for indoor use. 15. Turn the Meter power off when it is not in use and take out the battery when not using for a long time. Constantly check the battery as it may leak when it has been using for some time, replace the battery as soon as leaking appears. A leaking battery will damage the Meter.

Range Introduction Remark The approximate forward voltage Open circuit voltage: about 1.5V drop will be displayed The built-in buzzer will sound if the Open circuit voltage: about 0.5V resistance is less than about 30Ω. Overload Protection: 250V DC/AC rms For continuity test: When the resistance is between 30Ω and 100Ω, the buzzer may sound or may not sound. When the resistance is more than 100Ω, the buzzer won’t sound. 6.

Select auto range or manual range with the “RANGE” button. 3) In manual range, if the voltage magnitude to be measured is unknown beforehand, select the highest range. 4) Connect the test leads across the source or load to be measured. 5) Read LCD display. The polarity of the RED lead connection will be indicated when making a DC measurement. NOTE: a. In small range, the meter may display an unstable reading when the test leads have not been connected to the load to be measured. It is normal and will not affect the measurements. b. In manual range mode, when the meter shows the over range symbol “OL”, a higher range must to be selected. c. To avoid damage to the meter, don’t measure a voltage which exceeds 600Vdc (for DC voltage measurement) or 600Vac (for AC voltage measurement). Measuring Current 1) Connect the BLACK test lead to the “COM” jack. 2) Set the range switch to desired µA or mA range. If the current magnitude to be measured is not known beforehand, set the ranges switch to the highest range position and then reduce it range by range until satisfactory resolution is obtained. 3) Select DC current measurement or AC current measurement with the “SELECT” Button. 4) Select auto range or manual range with the “RANGE” button. In manual range, if the current magnitude to be measured is not known beforehand, select the highest range. 5) Connect test leads in series with the circuit to be measured. 6) Read the reading on the display. For DC current measurement, the polarity of the red test lead connection will be indicated as well. NOTE: When the display shows the over range symbol “OL”, a higher range must be selected. OPERATION OPERATION CONT. Measure Resistance 1) Connect the BLACK test lead to the “COM” jack and the RED to the “INPUT” jack (Note: The polarity of the red test lead is positive “+”). 2) Set the range switch to Ω range 3) Select auto range or manual range with the “RANGE” button. In manual range, if the current magnitude to be measured is not known beforehand, select the highest range. 4) Connect the test leads across the load to be measured. 5) Read the reading on the display. NOTE: a. For resistance measurements >1MΩ, the meter may take a few seconds to stabilize reading. This is normal for high-resistance measurement. b. When the input is not connected, i.e. at open circuit, the symbol “OL” will be displayed as an over range indicator. c. Before measuring in-circuit resistance, be sure that the circuit under test has all power removed and all capacitors are fully discharged. Continuity Test 1) Connect the BLACK test lead to the “COM” jack and the RED to the “INPUT” jack (Note: The polarity of the red test lead is positive “+”). 2) Set the range switch to range 3) Press the “SELECT” Button to select continuity measurement mode, and the symbol “ ” will appear as an indicator. 4) Connect the test leads across the load to be measured. 5) If the circuit resistance is lower than about 30Ω, the built-in buzzer will sound. Diode Test 1) Connect the BLACK test lead to the “COM” jack and the RED to the “INPUT” jack (Note: The polarity of the red test lead is positive “+”). 2) Set the range switch to range 3) Press the “SELECT” Button to select continuity measurement mode, and the symbol “ ” will appear as an indicator. 4) Connect the red test lead to the anode of the diode to be tested and the black test lead to the cathode. 5) The meter will show the approximate forward voltage of the diode. If the connections are reversed, “OL” will be shown on the display. Battery Test 1) Red lead to ”VΩmA”, Black lead to ”COM” 2) RANGE switch to desired ”BATT” position. 3) Connect red test lead to the battery’s negative. 4) The display will read the battery’s voltage. Auto Power Off If you don’t operate the meter for about 15 minutes, it will turn off automatically. To turn on it again, just rotate the range switch or press a button. If you press the “SELECT” button and turns on meter, the automatic power-off function will be disabled. Battery Replacement If the sign “ ” appear on the display, it indicates battery should be replaced. Remove screws and open the back case, replace the exhausted battery with new batteries (Size AAA, 1.5V x2 or equivalent). Fuse Replacement Fuse rarely needs replacement and is blown almost always as a result of operator’s error. To replace the fuses, open the battery cover; replace the damaged fuse with a new fuse of the specified ratings. Reinstall the battery cover and lock this cover.
