Total error
The total error of the measuring device comprises the total performance and the influence of long-
term stability and is calculated using the following formula:
Total error = total performance + long-term stability
Calculation of the total error with the Endress+Hauser Applicator
Detailed measured errors, such as for other temperature ranges, for example, can be calculated with
the Applicator "Sizing Pressure Performance".
