SETUP FOR CALIBRATION

This section provides calibration setup for GPIB, RS232 and Ethernet; note
that Step 6 provides separate instructions for each control interface.

STEP DESCRIPTION

1. Disconnect the Unit Under Test (UUT) AC input power. (The UUT is

the power supply that will be calibrated.)

2. Disconnect all loads from the UUT’s output terminals.

3. Connect the UUT sense lines to the output terminals. Refer to the

power supply operation manual for further information on remote
sensing.

4. Connect the DVM to the UUT output terminals.

5. Set the UUT to REMOTE mode by the rear panel S1 DIP switch.

6. Perform one of the following:

For GPIB:

Ensure that the correct GPIB primary address has been set by the
UUT rear panel DIP switches for SGA or via the UUT front panel
Remote menu for SGI. Connect the GPIB controller to the rear
panel of the UUT using a GPIB cable.

For RS232:

Connect the RS232 controller to the rear panel of the UUT using
the RS232 null modem cable (see Figure 3-4 of this manual).

For Ethernet:

Refer to Section 5.2 of this manual for Ethernet communication
setup.
Connect the RJ-45 Ethernet cable to the rear panel of the UUT.

7. Reconnect the AC input power. Turn the unit ON and allow the unit to

warm up for at least 30 minutes.

The UUT is ready for the calibration procedure to be performed.

WARNING

Exercise caution when using and servicing power supplies:

High energy levels can be present at the output terminals on all power
supplies in normal operation.

Potentially lethal voltages exist within the power supply and on the output
terminals of power supplies that are rated at 40V and over.

Filter capacitors store potentially dangerous energy for some time after
power is removed.
