Heathkit IM-30 Transistor Tester

Checks: Transistors up to 15 amps and diodes up to 1.5 amps.

Tests: Shorts, DC Gain (Beta 0-300) (Alpha 0-.9967), Leakage (Icbo, Iceo),
       Diode Forward and Reverse Current.

Meter:
Current Ranges: 15 ua, 150 ua, 1.5 ma, 15 ma, 150 ma, 1.5 A, 15 A;
Voltage Ranges: 1.5 V, 5 V, 15 V, 50 V, 150 V(100k ohm/volt).

Power supply: Internal, seven 1.5 volt size D batteries provide 1.5, 3, 4.5, 6, 7.5, 9 volts
collector suipply for gain or leakage and 1.5 volts for bias; External 0-50 volts for gain,
0-150 volts for leakage and 1.5 volts for bias.

Bias control: Permits any collector current from 10 ua to 15 amps for gain tests.

Gain control: 3% wire-wound potentiometer has calibrated scales to give DC Beta and DC Alpha
directly when meter is at null.

Lever switch:
Four spring return levers will individuially select the following tests: Base Current, Gain,
Collector Voltage, Collector Current, Leak Voltage, Short Test, Icbo and Iceo or diode currents.

Two voltage selector switches: Gain and Leak Test Voltages can be individually preset at different
voltage levels.

Two current range switches: Collector and Leak currents can be individually preset on different ranges.
Transistor and diode connections: Universal transistor socket and binding posts.

External power supply connections: Binding posts for Gain, Leak and Bias supplies.
