In constant current mode, the current values between the meter mode and
limit mode are the same, but the voltage values are not. Moreover, if the
display is in the meter mode, you cannot see the change of voltage limit
value when adjusting the knob. We recommend that you should set the
display to the limit mode to see the change of voltage limit value in the
constant current mode whenever adjusting the knob.
[1] You can use the resolution selection keys to move the flashing digit to the right
or left when setting the voltage.
