3. Adjust Sensitivity
Vertical scale adjusting has Coarse and Fine two modes, Vertical sensitivity range is 2mV/div ～ 10V/div
scale.
Take the CH1 for example:
● Press “CH1”→“Volts/Div”→“Coarse”. It is the default setting of Volts/Div, and it makes the vertical scaling in
a 1-2-5-step sequence from 2mv/div, 5mv/div, 10mv/div to 10v/div.
● Press “ CH1” → “ Volts/Div” → “ Fine” . This setting changes the vertical to small steps between the coarse
settings. It will be helpful when you need to adjust the waveform vertical size in smooth steps.
4. Setting Probe Attenuation
In order to assort the attenuation coefficient, you need to response in the channel operation Menu. If the
attenuation coefficient is 10:1, the input coefficient should be set to 10X, so that the mistake of the Volts/div
information and measure testing should be forbidden.
Take the CH1 for example, when you use the 100:1 probe:
● Press“CH1”→“Probe” →“100”
Set to
Coarse
