1. Press SHIFT key; display resembles A or B below.
2. Press Vadj key to command the power supply to go into Voltage mode.; the display will
briefly display the message shown below:, then return to the “Output is OFF” or “Keypad
Control” message displayed before the SHIFT key was pressed.
CURRENT MODE — Commanding the power supply to go into Current mode causes the inter-
nal microprocessor to compare the output current to the programmed current and the output
voltage to the voltage limit to determine when an error condition has occurred. While the power
supply is in Current mode with the output enabled, the output current will remain constant at the
programmed value, while the voltage will vary depending on the value of the load. If the load is
