| Error max : The maximum error mentioned in our technical specifications corresponds to the acceptable maximum difference between the variation of lowest measurement and the variation of highest measurement, compared to the standard value, on all the travel of the instrument. The local error is in a general way lower than this value. A certificate of calibration delivered with all our instruments with a resolution of 1 urn, this one indicates the effective maximum error of the instrument, controlled in our laboratory. The repeatability determines the maximum interval in which will be a series of measurements taken at the same point of the travel of the instrument by the same operator and under the same conditions. |
