Error Limits
The error limits (Accuracy and Coefficient of Variation) mentioned below are
in accordance with the nominal capacity (or maximum volume) indicated on
the instrument. These are obtained by using the instrument with distilled water
at equilibrium, ambient temperature of 20 °C or 68°F, while operating the device
smoothly and steadily.
The error limits are well within the limits of DIN EN ISO 8655-5.
