The operation modes Pulse Pause fixed Pulse variable and Pause variable make sense when the meas ured size redox value reacts only slowly and delayed to the controller activities or only small amounts of substances should be added For these operation modes you have to make the following settings e Pulse duration The corresponding socket is switched on for this duration at the maximum A pulse duration be tween 1s and 1h can be set e Pause duration This is the maximum time until the control can switch on the corresponding socket again A pause duration between 1s and 1h can be set 3 9 Conductivity This allows you to configure the functions relating to the conductivity or the salinity density in the marine aquarium In the event that several conductivity electrodes with the appropriate electronic metering are pre sent you should first of all select the sensor to be configured the inputs are numbered sequentially from left to right viewed from the rear The conductivity can be adjusted downwards and upwards or both together For this the relevant switchable socket functions must be configured There are 2 different types of conductivity measurement cards with different ranges available 0 to 2000uS for freshwater aquaria 0 to 100mS for marine aquaria Depending on the range chosen the following parameters can be set as described 3 9 1 Nominal value Fresh water The nominal conductivity value can be set in steps of 1uS w
