1.Ensure that the power supply is turned OFF. Disconnect any load.
2.Connect the program source between J2 connector terminals 8 (output current limit programming input) and 7 (current program signal return).
3.Connect the shunt and DVM across the power supply output.
4.Turn the power supply ON.
5.Apply 1% of program voltage.
6.Adjust the current limit program offset (R469) until the shunt/DVM indicates 1% of the
7.Apply 100% of program voltage.
8.Adjust the current limit program range (R459) until the shunt/DVM indicates the
Repeat this procedure until output levels are adjusted to power supply specifications (see Section 1) or to the accuracy that your application requires.
Note:Calculate the required DVM reading using V= IR where V is the DVM reading, I is the current, and R is the DC shunt resistance.
