Setting the Current Limit
Before you begin using the PS280 or PS283 to power a device, you
should set its current limit lower than the maximum safe current for
the device to be powered.
CAUTION. In order to avoid damaging your device with a current
overload, set the current limit on the PS280 or PS283 before you
connect it to your device.
1. Determine the maximum safe current for the device to be
powered.
2. With the test lead, temporarily short the positive and the negative
output terminals of the power supply together.
