SETTING CURRENT LIMIT
1. Determine the maximum safe current for the device
to be powered. If that value is greater than 0.25 A
for Model 1710A, or greater than 0.5 A for Model
1730A, set the High-Low switch to High. If less
than these values, set High-Low switch to Low.
2. Temporarily short the (+) and (-) terminals of the
power supply together with a test lead.
3. Rotate the Coarse VOLTAGE control away from
zero sufficiently for the CC indicator to light.
4. Adjust the CURRENT control for the desired
current limit. Read the current value on the A meter.
5. The current limit (overload protection) has now
been preset. Do not change the CURRENT control
setting after this step.
6. Remove the short between the (+) and (-) terminals
and hook up for constant voltage operation.
