Select the "ON/OFF" switch. The switch will light up simultaneously
with the CH1-CH4 channel keys. Then proceed to define the
parameter to be changed: voltage ("V SET") or current ("I SET").
Enter the desired value from the numeric keypad or using the control
knob to save the information in the appropriate memory space of the
device. Confirm with "ENTER".
Each time the parameters are selected an audible signal will be
triggered.
B. Defining values for a given channel
Using the control panel, define the corresponding channel CH1-CH4
to which the value should be assigned. The selected switch will light
up. Press the "ON/OFF" switch. The switch will light up. Then proceed
to define the parameter to be changed: voltage ("V SET") or current
("I SET"). Enter the desired value from the numeric keypad or using
