potentiometer to a required voltage value and then press the “OUTPUT” button. While the
voltage is available at the binding post, at the moment, the constant-voltage mode starts
operating. If the voltage value drops, in this case the instrument is in constant-current Mode,
should set the CC setting potentiometer to the extreme position clockwise.

Preset a constant–current point and set the output current of the unit. By above,
mentioned method, after the constant-voltage point is set, press the “A” button and output
terminal is shorted, turn on the “OUTPUT” switch. After the current setting potentiometer is
set to the required value.
To keep the voltage position, turn off the “OUTPUT” switch and remove the short bar,
connect the 1oad, press the “ OUTPUT” switch, the instrument provides the required current
and voltage for the load.

Turn on the “POWER” switch and the “OUTPUT” switch, the external control voltage
is applied through the jack on the rear panel of the unit. Adjust “VOLTAGE” switch of the
potentiometer to the extreme position clockwise, adjust the external control voltage so that
the output voltage becomes the desired voltage.
The relationships between the output voltage (Eo) and the external control voltage
(El) is expressed as follows:
