SETUP FOR CALIBRATION

10.2
This section provides calibration setup for RS232, Ethernet.
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 DVM to the UUT output terminals.
4. Perform one of the following:
For RS232:
For Ethernet:
5. 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.
Exercise caution when using and servicing power supplies:

STEP
1. Issue a *CLS command.
2. Issue a *RST command.
Program the overvoltage protection to maximum to prevent nuisance trips:

M330461-01 Rev A
Connect the RS232 controller to the rear panel of the UUT using the RS232
null modem cable (see Figure 4-3).
Refer to Section 6 for Ethernet communication setup. Connect the RJ-45
Ethernet cable to the rear panel of the UUT.
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.
