8. (Iceo). (L I) testing

  • Connect the red test lead to Positive (P). the black test lead to (COM)
  • Set the finction/function range switch to "Q", set the appropriate function, for the higher power transistor select 150mA (xl) range; while for the lower power transistor, select 15mA (x10)range.
  • Short the test leads together, using the zero ohms adjustment dial, slowly turn the dial until the needle indicator reads 0 ohms at the right end of the ohms scale.
  • NPN type transistor, connect the red test leads to the emitter terminal of transistor (E), the black test leads to the collector terminal of transistor(G). However for PNP type transistor, the connect way should be reversed
  • When the reading value during the range of red color LEAK, then it is good, otherwise is defective

9. hFE testing

  • Connect the red test leads to Positive (P), the black
  • Set the function/function range switch to hEF (x10) in range of "R".
  • Short the test leads together, using the zero ohms adjustment dial, slowly tum the dial until the needle indicator reads 0 ohms at the right end of the ohms scale.btransistor socket of the unit. directly.
  • Insert NPN or PNP transistor under test into the
  • In the scale of hEF, current amplification can be read directly.
