  • Page 2: Safety Information

    This Operating Manual covers information on safety and cautions. Please read the relevant information carefully and observe all the Warnings and Notes strictly. Warning Unpacking Inspection Open the package case and take out the Meter. Check the following items carefully to see any missing or damaged part: Item Description...
  • Page 3 Rules For Safe Operation 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:  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.

  • Page 4: The Meter Structure (See Figure 1)

     Turn the Meter 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.

  • Page 6: Measurement Operation

    Symbol Meaning A: Amperes (amps). The unit of current. mA: Milliamp. 1 x 10 or 0.001 amperes µA : Microamp. 1x 10 or 0.000001 amperes F: Farad. The unit of capacitance. µF : Microfarad. 1 x 10 or 0.000001 farads. nF : Nanofarad.
  • Page 7 Note  In each range, the Meter has an input impedance of 10M except mV range which input impedance is 3000M . This loading effect can cause measurement errors in high impedance circuits. If the circuit impedance is less than or equal to 10k , the error is negligible (0.1% or less).
  • Page 8 Note  If the value of current to be measured is unknown, use the maximum measurement position, and reduce the range step by step until a satisfactory reading is obtained.  For safety sake, each measurement time for >5A current should be less than 10 seconds and the interval time between 2 measurements should be greater than 15 minutes.
  • Page 9 D. Testing for Continuity (See figure 5) figure 5 Warning To avoid damages to the Meter or to the devices under test, disconnect circuit power and discharge all the high-voltage capacitors before testing for continuity. To avoid harm to yourself, do not input higher than DC 60V or AC 30V voltages. To test for continuity, connect the Meter as below: 1.
  • Page 10 E. Testing Diodes (See figure 6) figure 6  Connect the test leads to the proper terminals as said above to avoid error display. The LCD will display OL indicating diode being tested is open or polarity is reversed. The unit of diode is Volt (V), displaying the forward voltage drop readings.
