Readjustment of the measured value. For this purpose, previously the free chlorine had
been measured by DPD1.
It is recommended to perform the first manual calibration with a solution that does not
contain chlorine and after that repeat the calibration using a solution with known chlorine
concentration.
1. From the main menu select
2. Select the channel to calibrate and confirm.
3. Select
CAL. REFERENCE VALUE
Note: The manual calibration does not cause any change in the stage of the relays and the 4-20 mA
output. During calibration the instrument still regulates.
4. Adjust the measured value using the keypad.
5. Press to accept calibration.
OK
Note: Bear in mind that the electrode response is slow.
It erases the calibration data in memory and returns to the calibration data from factory.
1. From the main menu select
2. Select the channel and confirm.
3. Select
RESET CALIBRATION
Note: Prior measure, it is obligatory to carry out a calibration against DPD1.
Note: The theoretical calibration does not cause any change in the stage of the relays and the 4-20
mA output.
The display shows the chlorine concentration in ppm measured by chlorine sensor and the
temperature.
Temperature readjustment, see detailed information on
The model 53 59 is a galvanic cell for measurement of free chlorine in water.
Sensor installation
The electrode is delivered ready for installation. It must be installed in bypass. It is
supplied with connection joints of 8 mm. Minimum flow: 90-100 L/h. Refer to
Chlorine sensor installation, page
It is obligatory to install a filter before the sensor. It is recommended as well to install a
rotary meter ensuring the flow.
Startup
When the sensor is installed for the first time or the instrument has been disconnected
from the power supply, the user should wait at least 30 min before calibration or start of
regulation. This time can me programmed in "Regulation Delay", see
modification, page 22.
