Procedure

• Do not initially turn on the power supply. Connect the circuit after having made precision measurements of the resistors. Turn on the power supply only with the circuit completely connected, Install the resistor value RSET in the Digital Control of DCCheck.vi. Run the VI. Check the dc values. Verify that ISET is roughly 25μA VO is normally close to V+ or V–. Default and save the Front Panel.
