Agilent Technologies Comprehensive Calibration and Verification Procedures for 6031A Power Supply

Calibration and Verification

Introduction

This section provides test and calibration procedures. The operation-verification tests comprise a short procedure to verify that the unit is performing properly, without testing all specified parameters. After troubleshooting and repair of a defective power supply you can usually verify proper operation with the turn-on checkout procedure in the Operating Manual. Repairs to the A1 main board, the A2 control board and the A8 GPIB board can involve circuits which, although functional, may prevent the unit from performing within specified limits. So, after A1, A2 or A8 board repair, decide if recalibration and operation verification tests are needed according to the faults you discover. Use the calibration procedure both to check repairs and for regular maintenance.

When verifying the performance of this instrument as described in this chapter, check only those specifications for which a performance test procedure is included.

Test Equipment Required

Table 2-1 lists the equipment required to perform the tests of this section. You can separately identify the equipment for performance tests, calibration and troubleshooting using the USE column of the table.

Operation Verification Tests

To assure that the unit is performing properly, without testing all specified parameters, first perform the turn-on checkout procedure in the Operating Manual. Then perform the following performance tests, in this section.

Voltage Programming And Readback Accuracy

Current Programming And Readback Accuracy

CV Load Effect

CC Load Effect

Calibration Procedure

Calibrate the unit twice per year and when required during repair. The following calibration procedures should be performed in the sequence given.

Note: Some of the calibration procedures for this instrument can be performed independently, and some procedures must be performed together and/or in a prescribed order. If a procedure contains no references to other procedures, you may assume that it can be performed independently.

To return a serviced unit to specifications as quickly as possible with minimal calibration, the technician need only perform calibration procedures that affect the repaired circuit. Table 2-2 lists various power supply circuits with calibration procedures that should be performed after those circuits are serviced.

If the GPIB board (A8) has been replaced, you must first initialize the board before you can calibrate the unit. Refer to Page 31.
