3.3.1 < Sens>: Setting the Full Scale Sensitivity
Choose an appropriate full-scale sensitivity according to the amplitude of the input signal. Adjust the value through
the soft keys or spin knob.

The charge of <Sensitivity> will change the dynamic range of the system. Besides, it will impact the output of
CH1&CH2. If the measure signal is current, the full scale acts as the corresponding current unit, <100mV/nA> in
default.
3.3.2 < DR>: Setting the Dynamic Reserve Mode
<Low>
Low dynamic reserve mode
<High>
High dynamic reserve mode.
<Normal>
Normal dynamic reserve mode. Generally, this mode is recommended.
