86115B Module Specifications
86115B module specifications and characteristics apply when a module is installed in the instrument mainframe. The following notes refer to the module specifications listed in this chapter.
All specifications describe warranted performance over the temperature range +10° C to + 40° C (unless otherwise noted). The specifications are applicable after the temperature is stabilized, which occurs after 1 hour of continuous operation and while module calibration is valid. Many performance parameters are enhanced through frequent, simple user calibrations.
Specifications describe warranted performance. Characteristics provide useful, nonwarranted information about the functions and performance of the instrument. Characteristics are printed in green italics.
Factory Calibration Cycle. For optimum performance, the instrument should have a complete verification of specifications once every 12 months.
Nominal Value indicates the expected, but not warranted, value of the parameter.
| Item | Description |
|---|---|
