Set the rotary switch at desired ”V~”range position.
TRANSISTOR TEST 1. Set the rotary switch at "hFE" position. 2. Determine whether the transistor under testing is NPN or PNP and locate the emitter base and collector leads. Insert the leads into proper holes of the hFE socket on the front panel. 3.
WARNING To avoid electric shock, be sure the thermocouple has been removed before changing to another function measurement. BATTERY & FUSE REPLACEMENT If " " appears on display, it indicates that the battery should be replaced. Fuse rarely need replacement and blow almost always as a result of operator’s error.
