Measures common-
emitter gain.
hFE Transist or Test
The 2704C has all of the functionality for basic DMM applications including
some high end features you might not expect. The 2000 count LCD can display
resistance values up to 2 GΩ, capacitance to 20 uF or a transistors
common-emitter gain value up to 1000. Value-packed features make this meter a
must in every "Tool Kit
®
".
