Agilent Technologies 6010a, 6011A, 6012B, 6015A service manual Initial Setup, Calibration Procedure

Page 12

Initial Setup

Maintenance described herein is performed with power supplied to the instrument, and protective covers removed. Such maintenance should be performed only by service trained personnel who are aware of the hazards involved (for example, fire and electrical shock). Turn off ac power when making or removing connections to the power supply. Where maintenance can be performed without power applied, the power should be removed.

a.Unplug the line cable and remove the top cover by removing the two screws.

b.Slide the cover to the rear.

c.Plug a control board test connector A2P7 onto the A2J7 card-edge fingers.

d.Turn OVERVOLTAGE ADJUST control A3R97 fully clockwise.

e.Disconnect all loads from output terminals.

f.Connect power supply for local sensing, and ensure that MODE switches are set as shown below.

g.Reconnect the line cable and turn on ac power.

h.Allow unit to warm up for 30 minutes.

i.At the beginning of each calibration procedure, the power supply should be in its power-off state, with no external circuitry connected except as instructed.

j.The POWER LIMIT adjustment (A2R25) must be adjusted at least coarsely before many of the calibration procedures can be performed. If you have no reason to suspect that the Power Limit circuit is out of adjustment, do not disturb its setting. Otherwise, center A2R25 before you begin to calibrate the power supply.
