    CAUTION: • Before making measurements ensure that the function selector switch is set on the appropriate range position • Always make sure that the plug of each test lead is inserted fully into the appropriate terminal of the meter. • Ensure that the function selector switch is set to the “OFF” position after use. When the meter will not be in use for a long period of time, place it in storage after removing the battery.

    4. Connect the other end of the test leads to the component under test. Read the display Note: • Use the diode test to check diodes, transistors, silicon controlled rectifiers (SCR’s) and other semiconductor devices. • The test sends a current through a semiconductor junction, then measure the junction’s voltage drop.
  • Page 18: Data Hold Functions

    Note: • Using resistance and continuity function in a live circuit will produce false results and may damage the instrument. • In many cases the suspicious components must be disconnected from the circuit under test to obtain accurate results. • WARNING Before attempting to make a test ensure there is no voltage present on the circuit.
  • Page 19: Peak Hold Functions

    17. PEAK HOLD This is a function used to record the maximum and minimum readings on the display for the voltage and current ranges. 1. Press the button once. This will record the „PEAK” maxiumum, the meter beeps and display the „P-MAX” indicator on the LCD. 2.
