Warning: To avoid electrical shock when measuring high voltage
with probe, please ensure that the insulation lead of the probe is in
good condition and do not contact the metal part of the probe
when connecting to power supply.
5. Automatic Setting of Waveform Display
The oscilloscope has automatic setting function. According to input signals,
automatically adjust the vertical deflection factor, scanning time base and trigger mode
until the most appropriate waveform is displayed. In automatic setting, the frequency of
the measured signal is required to be ≥ 50Hz and the duty ratio is > 1%.
Apply automatic setting
1. Connect measured signal to signal input channel.
2. Press AUTO key. The oscilloscope will automatically set its vertical deflection factor,
scanning time base and trigger mode. If further careful observation is required, adjustment
can be conducted again after automatic setting until the waveform display reaches required
optimum effect.
6. Introduction to the Vertical System
As shown in the figure on next page, there are a series of keys and knobs in the vertical
control area. Practices below will gradually guide you to get familiar with the controlling
of the vertical system .
