10.1 Measurements: Adjustment of setpoints and measuring probes.
10.2 Setpoints for each measurement.
10.3 Setpoints:
pH: 7.0-7.4; redox: 600 - 800 mV; free chlorine: 0.1- 0.5 ppm; conductivity:
~ 2000 μS

10.22 Temperature calibration: To set the difference
between the measured value of the probe and the actual
temperature, use the plus/minus and up/down keys.
Set to the actual temperature of the probe and press OK.
Let the system run 24 hours before calibrating and make sure
to have a free chlorine level of at least 0.3 ppm free chlorine!

10.31 Calibration of the Free Chlorine probe:
Recommended at least every 2 to 3 months
10.32 Calibration with buffer (photometer
DPD1): Follow the instructions in 6 steps that
appear in the display.
10.33 Step 1 of 6 - Calibrate Cl at 0 ppm
(offset): Close the water flow through the probe
and wait for 5 to 60 min until the reading is close
10.34
10.35
to 0. Press OK
10.34 Step 3 of 6 - Calibrate Cl: Set the water
flow to the correct rate of 80-100 litres/hour.
Wait for 5 to 20 min until there is a stable ppm
reading. Press OK.
10.35 Step 5 of 6 - Establish the real ppm
values with the plus/minus keys according to
your DPD1 (free chlorine) value
10.36 Step 6 of 6 - If this screen is not shown
10.37
10.38
repeat the calibration process.
4.38 Manual calibration: Open the water flow
and set the flowmeter (rotameter) to the correct
flowrate (50-100l/h). Wait until the current level
is stable. Set the chlorine level with the plus/
minus keys, manually (use a manual DPD1 test
kit). Press OK when value is correct.
10.11 Calibration of pH probe: Recom-
mended at least every 2-3 months during the
usage season. Calibrate it always first with
the Buffer (2pt).
10.12 Calibration with buffers (buffer pH7 /
pH10 / neutral): Follow the instructions that
appear on the display.
10.14
Manual
calibration:
manual adjustment of the probes – only
recommended to correct small deviations in
the readings.
10.15 Without removing the probe from the
water, use the plus/minus keys to adjust the
reading so it matches your reference value
(photometer or other measurement).
