Operating Instructions
General Information:
The 30MHz Dual Trace
Scientech 801C
is a compact, low line and just trouble free
new generation Oscilloscope. It is technically advanced, as particularly illustrated by
the increased use of microcontroller circuits. The logical arrangement of the controls &
connectors makes it easy to become familiar with the operation of the instruments.
However, even, experienced users of Oscilloscopes should read the following
instructions thoroughly before using the instrument.
Operating Conditions:
Ambient temperature range for operation: 0
C - 40
C; 90% RH
Ambient temperature range for storage transportation: - 20°C to + 70°C.
The instrument should be placed in a clean and dry room and should be operated in
normal position; however, the convection cooling must not be impaired.
First Time Operation & Presetting:
At the time of delivery, the instrument is set at 230VAC mains voltage. To obtain a
display:
All push buttons should be in the released position.
Instrument is turned ‘On’ by pressing "Power" ON button. An LCD indicates that
the instrument is ‘On’. It is recommended to switch on the instrument for about
30 minutes prior to commencement of any calibration check.
If no trace is visible after a warm-up of one minute:
a.
Check "Intensity". It is possible that this control needs to be increased,
rotate knob clockwise.
b.
Bring X&Y “Shift” controls in the centre. Check Auto/Level controls bring
it in Auto position.
If only a dot appears [Caution, the CRT phosphor could be damaged under this
condition probably] the push button for XY is pressed. If this is so, it should be
released.
Now, the trace should appear and the "Intensity" control should be adjusted for
average brightness, while optimum sharpness is obtained by adjusting the "Focus"
control.
At the same time both input coupling switch "DC-AC-GND" should be in the
"GND" position. Thus, the inputs of the Y-amplifiers are grounded preventing the
introduction of unwanted signals.
Check Time/Div. & Volts/Div. function by using rotary knobs.
