How to Implement Self-calibration
The self-calibration application can make the oscilloscope reach the optimum condition
rapidly to obtain the most accurate measurement value. You can carry out this application
program at any time. This program must be executed whenever the change of ambient
temperature is 5
℃
or over.
Before performing a self-calibration, disconnect all probes or wires from the input
connector. Push the
Utility
button, select
Function
in the bottom menu, select
Adjust
. in
the left menu, select
Self Cal
in the bottom menu; run the program after everything is
ready.
Introduction to the Vertical System
, there are a few of buttons and knobs in
Vertical Controls
. The
following practices will gradually direct you to be familiar with the using of the vertical
setting.
Figure 3-11 Vertical Control Zone
1.
Use the
Vertical Position
knob to show the signal in the center of the waveform
window. The
Vertical Position
knob functions the regulating of the vertical display
position of the signal. Thus, when the
Vertical Position
knob is rotated, the pointer
of the earth datum point of the channel is directed to move up and down following
the waveform.
Measuring Skill
If the channel is under the DC coupling mode, you can rapidly measure the DC
component of the signal through the observation of the difference between the wave
form and the signal ground.
If the channel is under the AC mode, the DC component would be filtered out. This
mode helps you display the AC component of the signal with a higher sensitivity.
