Total Error Band (TEB) is the difference between the most negative and most positive deviation from the true measurement, determined from the combination of all known errors for a sensing device, within the constraints of the measurement and operating temperature range.
Typically in the case of a pressure measurement device for example, the total error band statement will include maximum uncertainty errors for linearity, hysteresis, short term repeatability, temperature drift, zero offset and full span offset.
Often, particularly in the case of calibration equipment, the total error band will also include a long term drift error for a specified time period of 3, 6 or 12 months.
The total error band can be expressed as a +/- error by dividing the TEB in half.
