3.3 OPERATING INSTRUCTIONS
3.3.1 VOLTAGE CHECKING
A oscilloscope is set for 110V ± 10% , 220V ± 10% voltage. Before connecting the unit to the
mains supply, make sure that the correct voltage is being used. Incorrect mains voltage may
cause damage to the instrument.

(2) OPERATION
a.
Power on [1],
b. Power lights at [2],
c. Allow a warm-up period of 5 minutes, then adjust the intensity[3],
d. Adjust focus [4] for clearest line. If unstable, adjust level [9] .
(3) Horizontal Level Adjustment :
a. Slightly turn screws [21][23] counter clockwise, but do not remove;
b. Insert a straight end screw driver to [22], and whilst observing the waveform,
turn the screw driver in order to set the waveform parallel with the horizontal
line ;
c. Tighten screws [21] [23].
(4) Connect the calibration signal [5] to Y input terminal[19] with 1:1 probe
