  • Notes
  • The Hickok Model 870, DYNAMIC BETA TRANSISTOR TESTER, is designed to test all small, medium power, and power transistor under typical operating conditions.

    The Model 870 offers the features of two separate transistor test instruments:a)An AC BETA TESTER (Small Signal Test); b) A DC BETA Tester (Medium and Large Signal Test).

    The instrument may be operated with any data taken from a transistor handbook, specification sheet or chart.

    A rollchart listing all essential test information has been included in the instrument.

    The Model 870 is designed to perform the following functional tests: Icbo, AC Beta, DC Beta, Iceo, Ices, Icer, Vce.

    The instrument is AC powered (105-125V, 50-70Hz), but it uses also  two NiCd 6V batteries (800mAh and 80mAh) needed for the transistor measurements.
