  • Page 35: Pump Working Time, Cadence, Pump Overrun

    We advise to program measurement cycles so that the pump is not working at least 50% of the time. The pump working time depends on the parameters set for dilutions and the number of channels. Example n°1 of a measuring sequence: STAC: 1 one channel, no dilution Pump working time Dilution...
