Section 5. Calibration

Introduction

WARNING

Exercise caution when using and calibrating a power supply. High energy levels can be stored at the output voltage terminals on a power supply in normal operation. In addition, potentially lethal voltages exist in the power circuit and on the output and sense connectors of a power supply with a rated output greater than 40 V. Filter capacitors store potentially dangerous energy for some time after power is removed.

Adjustments to programming and readback accuracy for the power supply are made using cover-off procedures which must be performed by a service technician.

Calibration Setup

Service

Follow established antistatic procedures.

Environment

Work at a bench with adequate room and support for the unit under test and for

and

all equipment required.

Precautions

To reduce shock hazard, use only an insulated, straight-blade screwdriver when

 

calibrating trim potentiometers.

 

NEVER calibrate these units alone. Ensure that someone is present who can help

 

should an accident occur.

Equipment Required

You will need the following equipment when calibrating your power supply.

5 1/2 digit true RMS voltmeters (DVMs) (±0.05% accuracy) with test leads

Current shunt 1 mV/A (±0.25%) and connecting wire. The recommended current ratings for the DC shunt and connecting wire must be at least 10% greater than the power supply's output current rating. Please see Table 2.4, “Current Carrying Capacity for Load Wiring,” on page 45.

Non-conducting, straight-bladed screwdriver
