Resetting the Oscilloscope
Input Connections
To reset the Oscilloscope to the factory default settings:
1. Press the MENU key. The function menu appears on the right side of the screen
2. Press the MENU UP or MENU DOWN key to select FUNCTION. Three options
3. Press F1 to select Factory Settings. The oscilloscope will revert to the factory
Examine the bottom and the right side of the Oscilloscope. The Oscilloscope has seven
signal inputs: two safety BNC jack inputs (CH1 and CH2) for scope measurements, three
safety 4-mm banana jack inputs for Multimeter R, V and A measurements, and two
square jack inputs for Multimeter capacitance measurements.
Isolated inputs allow independent floating measurements between Multimeter and Scope.
Vertical scale factor is the voltage amplitude represented by a division in the vertical
direction of the display area. The user can amplify or attenuate the signal with this
scale factor and thus regulate the signal amplitude for the expected range.
Vertical zero position is referred to as the grounding data point through the
adjustment of which one can regulate the display position of the waveform on the
screen.
Primary time base refers to the time values represented by a division in the
horizontal direction of the display area.
Trigger horizontal position is the time deviation between the actual trigger point
and the screen central line which will be displayed as 0 at the center point of the
screen.
Trigger level position represents the voltage deviation between the actual trigger
level and the zero position of the triggering signal source channel.
