2. 

Determine  whether  the  transistor  is  PNP  of 
NPN type  and  locate  the Emitter,  Base  and 
Collector  leads.  Insert  the  leads  into  the 
proper holes of the hFE Socket on the front 
panel. 

3. 

The meter will display the approximate hFE 
value  at the condition  of  base current  10

µ

and V

CE

2.8V. 

 

BATTERY AND FUSE REPLACEMENT 

Fuse  rarely  need  replacement  and  blow  almost 
always as a result of operator error. 
If  “

”  appears  in  display,  it  indicates  that  the 

battery should be replaced. 
To replace battery & Fuse (500mA/250V) remove 
the  2  screws  in  the  bottom  of  the  case,  simply 
remove the old, and replace with a new one. Be 
careful to observe polarity. 

 
CAUTION 

Before  attempting  to  open  the  case  of  the 
instrument, be sure to disconnect test leads from 
any energized circuits to avoid shock hazard.
