The Remote voltage sensing of the front/rear panel terminals:
The remote voltage sensing circuit is to compensate the voltage drop
occurred on the power supply and load terminal during load adding.
When proceed the remote voltage sensing, the probe connected
between the output of power supply and the sensing terminal must
be removed. The output terminals of the front panel and rear panel is
parallel and connected with the sensing terminal, when use the
output of front panel, the sensing probe of the rear panel terminal
must be removed, and visa versa.

1)
CV Regulation
When the voltage drop between the (+) output terminal and positive
sensing point increases 1V, its voltage Load regulation must be add
another 5mV.
2)
Output Noise
A voltage load regulation effects could be occurred by any noise
which interferes the output terminal of the power supply. Therefore,
it will be helpful to reduce the output noise by paralleling two
sensing circuit of (S+) and (S-) and separating each other adequately,
then connect a single end to the ground terminal of power supply.
The relative configuration is as follows:

Panel Lock Key:
Press [LOCK] key can lock up the panel control knob to prevent any
setting change, now the [OUTPUT] key still works. Press again
[LOCK] key for a few seconds can release the lock setting.
