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 G, 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®".

Single-handed operation
The ergonomic design allows both left and right handed users to rotate the
knob while holding the meter in one hand. While one hand keeps the probe
on the circuit, the other hand changes the meter’s function. This speeds up
troubleshooting because you don’t have to locate the probe point in the
circuit again.
