Appendix; Specification List - Picotest M3500A User Manual

Appendix

This appendix contains the performance specifications of the M3500A. It
covers the AC, DC, Resistance, Temperature, and Frequency/Period
characteristics under a variety of conditions. It also contains the general
characteristics and accuracy calculations for your convenience. A lot of
efforts are made to make sure these specifications serve your needs for
production, engineering and/or research purposes. All specification
applies to M3500A unless noted otherwise.
