nVision.Serial.Numbers

Serial.Number.Location

Each product has a maximum of three serial numbers, one for the chassis and each of the
modules (upper and lower). Chassis serial numbers are located in the power bay or on the rear
of the product in the case of the Lab Reference. Module serial numbers are located on the mod-
ule and can also be viewed in the power bay of the Reference Recorder.
All serial numbers can be viewed using the nVision Summary screens or
in CrystalControl.

Serial.Numbering.System

Serial Numbers consist of 6 numbers, with the left most digit representing the year of
manufacture. For example: 937834 was manufactured during 2009.

Module.Specifications

Accuracy specifications include all effects of linearity, hysteresis, repeatability, tempera-
ture and stability within the specified operating temperature range for one year.
Exposure to environmental extremes of temperature, shock and/or vibration may warrant a
more frequent recertification period.

Pressure.Module.(PM).Specifications

Accuracy

.
X
30 to 100% of Full Scale . . . ±(0.025% of Reading), ±(0.05% of Reading), or ±(0.1% of Reading)
0 to 30% of Full Scale . . . . . ±(0.0075% of Full Scale), ±(0.015% of Full Scale), or ±(0.03% of Full Scale)
See Accuracies, Ranges and Resolutions charts for the appropriate accuracy statement for your module.
PM modules must be exercised whenever exposed to significant changes in environmental
conditions to achieve these specifications, and re-zeroed. To exercise a gauge, cycle the gauge
between zero (ambient barometric pressure) and the pressure of interest.
A properly exercised gauge will return to a zero reading (or return to the same ambient baro-
metric reading).
Pressure Modules (PM) are not recommended for continuous use at high vacuum.
