To display a signal automatically

Protek1000 Series has an Auto feature that automatically sets up the scope meter to best
display the input signal. Using Auto requires signals with a frequency greater than or equal
to 50 Hz and a duty cycle greater than 1%.
Press the AUTO button, the scope meter turns on and scales all channels that have
signals applied, and it selects a time base range based on the trigger source. The trigger
source selected is the lowest numbered input that has a signal applied.
Protek1000 Series scope meters have two-channels input and an external trigger input.
Connect a signal to the channel 1 input.
1. Connect a signal to the scope meter.
2. Press AUTO.
The scope meter may change the current setting to display the signal. It will automatically
adjust the vertical and horizontal scaling, the trigger coupling, type, position, slope, level,
and mode settings.
