DESCRIPTION
Press the power switch located on the right
side of the unit to the on position.
The default setting is constant V, and the
LED display shows zero value.
To display firmware version number, hold
down constant parameter key while turning

current The LED on the parameter key
corresponding to the selected constant
parameter will light up. The display shows
the zero value for the constant parameter.
Use the scroll key to enter the desired value.
Voltage: 10–300V adjustable in 1V increments.
Current: 4–400 mA adjustable in 1 mA
increments.
Note: If the scroll key is pressed constantly
for more than 5 units in either direction, +/-,
the values will increase/decrease in
increments of 10 to reach the desired value
faster.
Use the parameter key to select the limit
parameter. The maximum default value,
300V or 400mA, is displayed. Select a suitable
limit value to avoid excessive power
conditions for the application.
