I worked for them, that is their logo, but they were and are mainly a
component supplier.
The meter looks pretty straight forward, for checking small signal diodes and
transistors. Do you have specific questions ?
Note I am guessing its small signal bipolar transistors only, not JFET or MOSFET or
TRIAC or SCR or.....
I think the range switch is, on left, for beta and Ico measurements, on the right for
collector current measurements. But latter measurement is done on some base current,
maybe its a saturation measurement of collector current.
