During control mode pH 500 and mV 600 fulfill the where the minimum deviation (D1 or D2) is 0.5 pH (for following main tasks: pH 500) or 25 mV (for mV 600). - Page 10 An upper boundary is imposed for acid/base dosage time when relays are energized continuously, i.e. when relay works in ON/OFF mode or in proportional mode but in the latter case only if the relay is always ON. This parameter can be set through setup procedure.

Page 27: Taking Redox Measurements
TAKING REDOX MEASUREMENTS Redox measurements allow the quantification of the oxidizing or reducing power of a solution, and are commonly expressed in mV. Oxidation may be defined as the process during which a molecule (or an ion) loses electrons and reduction as the process by which electrons are gained. -
