CONTINUITY BEEPER
A continuity test beeper is standard, when checking short or
open circuit, it is not necessary to look at the meter. The
beeper sounds if continuity is present.
TRANSISTOR hFE MEASUREMENT
0 - 1000 hFE values of either p.n.p. or n.p.n. Transistor. (Test
condition: base dc current approx. 10 ma, VCE: approx. 2.8 V).
RS232 OUTPUT
Isolated (photo couple) RS232 serial data output, 9600 baud
rate. Other detail spec.
