How to Implement Auto-calibration
The auto-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, but when the range of variation of the ambient temperature is up to or over 5 , this program must be executed.
For the performing of the self-calibration, all probes or wires should be disconnected with the input connector first. Press the “Utility” button, then, press H1 button to call out the Function menu; turn the M knob to choose Adjust. Press H2 button to choose the option “Self Cal”; run the program after everything is ready.
Introduction to the Vertical System
Shown as Fig.4-9, there are a series of buttons and knobs in VERTICAL
CONTROLS. The following practices will gradually direct you to be familiar with the using of the vertical setting.
Fig. 4-12 Vertical Control Zone
1. Use the button “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 will be removed by filtration.
This mode helps you display the AC component of the signal with a higher
