*A = Accuracy, CV = Coefficient of Variation
The maximum error for a single measurement can be calculated from the sum of error limits EL = A + 2
× CV (e.g. for 10 ml: 120 µl + 2 x 20 µl = 160 µl).

Error limits in relation to the nominal capacity (= maximum
volume) indicated on the instrument at equal temperature
(20 ºC/68 °F) of instrument, ambient environment and dis-
tilled water. Testing takes place according DIN EN ISO 8655-
