5. Set the programming sources to the desired levels and turn the power supply ON.
The REM LED turns on. Adjust the external programming source to change the
power supply's output.
Please remember:
1. Any of the eight switches on SW1 is OFF (OPEN) when it has been flipped up
to break contact, ON (CLOSED) when flipped down to close contact.
2. Resetting switches SW1-3 or SW1-4, the programming scale selection switches,
may require that you recalibrate the programming circuit to maintain
programming accuracy. See Section 5. Calibration.
3. Switches SW1-5, SW1-6, SW1-7, and SW1-8 are not required for remote
programming. They remain at the settings you have selected for your
application.
4. Switches SW-1 to SW-4 can be set to their defaults (1 and 2 open, 3 and 4 closed)
unless otherwise specified in Table 4.2. See "Rear Panel SW1 Switch" on page
19 for default settings.
5. The control circuits have been designed to allow you to set output voltage and
current up to 5% over the model-rated maximum values. The power supply will
operate within these extended ranges, but we cannot guarantee full performance
to specification.
