above diagram are highlighted or flashing on the LCD.
3. Vertical Voltage Scale (volts/div)
Specify the value for each vertical division in V or mV.
EX) “2.0V/div” shows that each vertical division represents 2.0 V.
4. Horizontal Time Scale (time/div)
Specify the value for each horizontal division in sec or min.
EX) “1s/div” shows that each horizontal division represents 1 sec.
