If the continuity indication
is audible, the emitter-base
path is defect.
For NPN transformers, the polarity has to be modified for
each test
5.0 Torch Function
UNITEST TESTFIX and UNITEST TESTFIX electro-
nic are equipped with a torch funciton (steady bur-

the battery replacement.
Proceed as follows:
1. Disconnect the instrument from measurement
circuit.
2. Open the casing by pulling the rear casing cover
towards the bottom.
3. Insert new batteries, type 1,5 V IEC LR6 by re-
specting the polarity and close the casing again.
