2SD218 Transistor Acceptable Gain Readings Using PEAK DCA55

I have 5 NOS 2SD218 transistors that I tested on a PEAK DCA55 and the gains are 30, 8, 16, 6 & 23. Also, the transistor with a gain of 6 is showing "Resistor Shunt Between B-E". I'm not going to use these on the intended project because the values are all over the place. What would be considered acceptable values using the DCA55?

I'm not sure there is a right answer. IMO The DCA55 does not test at a high enough current to give reliable results on TO-3 output transistors.
The DCA75 when powered via USB does a better job, but I think they are both better suited to small signal devices. YMMV
 
Couldn't find hitachi data sheet but another manufacture has hfe=30-120 at Ic=4A and Vce=5V
