Appendix A -- Reference 3000 Specifications
All specifications are at an ambient temperature of 25 °C, with the Reference 3000 powered using the power
adapter shipped with the unit, standard shielded 60 cm cell cables, and the cell enclosed in a Faraday shield.
All specifications are after software calibration.
A numbered note qualifies many of the specifications. Many of these notes describe the method used to
measure a specification. The notes are found at the end of this appendix.
All specifications are subject to change without notice.
