The information in this topic is intended only for qualified service personnel. Some of the
procedures may expose you to hazardous voltages that could result in personal injury or
death. Do not attempt to perform these procedures unless you are qualified to do so.

Introduction

Use the procedures in this section to calibrate the Series 2600B System SourceMeter
(Models 2601B/2602B/2604B/2611B/2612B/2614B/2634B/2635B/2636B).
These procedures require accurate test equipment to measure precise DC voltages and currents.
Product specifications are subject to change. Listed uncertainties and test limits are provided only as
an example. Always verify values against actual product specifications.

Environmental conditions

Temperature and relative humidity
Conduct the calibration procedures at an ambient temperature of 18 °C to 28 °C (65 °F to 82 °F), with
relative humidity of less than 70 percent (unless otherwise noted).
Product specifications that are listed as 18 ºC to 28 ºC assume adjustment has been done at 23 ºC.
If the Series 2600B is adjusted at a different temperature, the specifications apply to ±5 ºC of that
adjustment temperature.
