Error limits refer to the dispensing volume set relative to the PD-Tip, obtained when instrument,
PD-Tip and distilled water are equilibrated at ambient temperature (20 °C/68 °F) and with
smooth operation. The testing is according to DIN EN ISO 8655-5.
The nominal volume is the maximum volume printed on the PD-Tip.
