Appendix A: Reference 600+ Specifications
All specifications are at an ambient temperature of 25°C, with the Reference 600+ powered using the
external power supply shipped with the unit, a standard shielded 60 cm cell cable, 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.
