The key to eliminating an error is knowing its source and type along with its polarity and
magnitude. Generally, the source is simple to detect and is represented by the specific
parameter. The type is usually a function of the instrument’s design and manufacturing
process. Within a given instrument, an error can be either random or systematic as well as
random or systematic within the instrument’s population. The user is free to consult
Fluke for recommended methods of minimizing error source contributions.
In summation, total error can and should be managed by the control of the three general
error sources: Input Specifications, which includes the user’s chosen calibration standards;
General Specifications, which includes the user’s chosen processes; and Performance
Specifications, which includes the user’s chosen applications for the instrumentation. The
parameters and value limits listed in the following specifications indicate the product
line’s general acceptance limits and are not a report of any unit’s specific error
contribution. Any parameter exceeding the specified limits should be considered in need
of maintenance.

Precision:
High Ranges to 20,000 psia: 0.01% FS of Active Range
High Ranges >20,000 psia: 0.02% FS of Active Range
Stability: High Ranges to 20,000 psia: 0.01% of Active Range/Year
High Ranges >20,000 psia: 0.02% of Active Range/Year
Resolution: 0.01% FS or better
Control Stability: Typically 0.01% FS for ranges less than 20K
0.02% FS for ranges greater than 20K
Control Range: Increasing: Atm. to Full Scale
Decreasing: Full Scale down to 400 psi, and vent to Atm.
Control Response: Values are noted into a 50 cc air free volume and reflect the
typical control speeds (or average time of multiple test points)
for the system. Increased volume or air in the system will
increase the control time. Decreasing volume will decrease the
control times.
Normal Control Mode: Time for 10% step size: 90 seconds
Time to vent: < 5 seconds
Pump Recycle time: 10 seconds
