4. POWER SUPPLY CONSIDERATION
1)The instrument is shipped along with an ACV ( 100V to
240V ) to DC 9V ( 3A ) adapter.
2)When operate the instrument, it should insert the
DCV output plug of DC adapter into the " DC 9V Power
Adapter Input Socket " ( 3-2, Fig. 1 ). Connect the
ACV input plug of DC adapter into the a properly
110V AC, 220V AC or 240V AC outlet.
Battery operation
The instrument also can operate by
batteries ( UM1/D type X 4 PCs ).
Due to high power consumption ( short
battery life ) for the Stroboscope function,
we do not recommend user operate the
STROBOSCOPE function via batteries.
However for the Tachometer function, as
the power consumption is lower, so if
user intend to use the batteries to operate
the TACHOMETER function, it is
convenient.
