Self-calibration
With the auto-calibration, the oscilloscope can be quickly set to the optimum state for highly accurate
measurements. You can run this programme at any time, but you must do so if the ambient temperature
varies by more than 5°C.
Remove all probes and cables from the input sockets before performing the auto-calibration. Press the
"UTILITY" button, then the "H1" button to enter the FUNCTION menu; turn the "Multipurpose" knob to
select "Adjust". Press the "H2" menu selection button to access the "Selfcal" option and start the
programme after confirming "OK" that all settings are correct.
Introduction to the vertical system
The following picture shows the buttons and keys for the VERTICAL CONTROL. The following exercises
will familiarise you with the vertical control step by step.
1. With the rotary knob
"VERTICAL POSITION" you can
display the signal in the centre of the waveform window. With
the "VERTICAL POSITION" adjustment knob, you set
the vertical display position of the signal. Turning the "VERTICAL POSITION" adjustment knob moves
the pointer of the channel's zero position up and down, following the waveform.
Measurement capabilities
If DC coupling is set for the channel, you can quickly measure the DC component of the signal by
observing the difference between waveform and signal ground.
If AC coupling is set for the channel, the DC component is filtered out. This mode helps you to display the
AC component of the signal with higher sensitivity.
