OPERATIONAL FUNCTIONS OF THE PLUS "METERING" PUMP

Selecting the configurations: ST and ST-T, the metering pump is placed in the control mode and in function of the
electrochemical parameter type selected (pH, RX, ppm Cl, ppm), it intervenes maintaining the correct set value. Once the
instrument configuration is set, you must select one of the following operating modes:
The pump instrument operates within the following measurement ranges:

Manual

Mode of operation similar to that described in the "proportional" version.
pH mode
In pH mode, the pump must be connected to a pH sensor and through the proper configuration of the setup menu. The
device is responsible for ensuring the maintenance of the set-point value and the management of all the devices connected
to the pump terminal box.
The pump offsets the displayed value in reference to the value of the measured temperature (PT100) or as reference it
uses the value set manually by the user.
In the configuration menu of the pH mode you can carry out the following settings:
Sensors made from either glass or plastic material can be used. Connect the probe as shown in Fig. 10
