phosphoric acid (orthophosphoric acid, H
3-
(anion PO
).
4
Measuring method The P 700 IQ phosphate analyzer measures the concentration of
orthophosphate in an aqueous solution with the aid of the vanadate
molybdate method (yellow method).
The reagent contains an aqueous solution of ammonium metavanadate NH
addition of sulfuric acid H
and ammonium heptamolybdate (NH4)6Mo7O24 with an
4VO3
. In an acidic environment, the chemical
2SO4
reaction takes place according to the following molecular formula:
) this is orthophosphate
3PO4
PO
3-
+ 2 VO
4
-
+ 10 MoO
3
2-
+ 20 H+ → [PV2Mo10O40]5- + 10 H2O
4
The originally pale yellow reagent will turn a deep yellow. The change
of absorbance is photometrically measured at a wavelength of 420 nm.
From this, the concentration of orthophosphate is calculated.
Citation forms Phosphate concentration is quoted in milligrams per liter (mg/l). This
value can either refer to all orthophosphate ions or only to the phosphorus atom included. The values can be converted as follows:
• 1 mg P = 3.066 mg PO4
• 1 mg PO4 = 0.3261 mg P
Concentration values referring to the phosphorus atom are indicated by
the addition PO4-P (citation form).

How it functions The photometer unit is supplied with d.c. voltage by the PS15V power
pack and operated by a controller (1). It communicates with the
ENSORNET through the MIQ/WCA 232 interface.
IQ S
In conjunction with the peristaltic pump (7), the valve block (6) controls
the movement of the liquids (sample, reagent, standard solution, cleaning solution).
The photometer unit draws the sample from the overflow vessel (5). Filtrated sample continuously flows through the overflow vessel. Thus the
sample is constantly available and free of air bubbles. The filtration unit
(available as an accessory) in conjunction with the filtration pump
(instrument option "P“) provides an optimally prepared sample.
The absorbance of the reaction mixture is measured in the optical block
(3). The optical block has an LED as the light source and photo diodes
as a detector. After the measurement, the liquid is removed from the
optical block.

The filtration pump continuously draws sample through the intake tube
(2) and pumps it into the overflow vessel (4) through the connection
tube (3). The flow rate can be set on the control panel (1). On the intake
side, a manometer (7) is installed for low pressure measurement.
For sample preparation, a sample filtration device (available as an
accessory) can be connected upstream.
The climate kit includes an electrical circulating air heating, two housing
ventilators and three temperature regulators. The temperature regulators switch on the heating or ventilators if the temperature is less than
+15 °C or more than 40 °C. Thus the analyzer with the door closed is
suitable for all-season operation in the open. The climate kit is automatically active when the switch on the power supply box is in the ON position.
Where there is a chance of frost, the intake tube and return

The FM filter membrane module consists of a separable housing and
two membrane inserts. With the aid of the M 1.5 attachment for filtration, the FM filter membrane module can be immersed in the measuring
medium and can be adjusted in height. To clean the membrane inserts,
the filter membrane module can be pulled out along a guide rail with a
chain.
The suction line consists of a suction tube in a robust sleeve tube. Suction lines are available in different lengths and, as frost protection, with

4.2 Calibration
4.2.1 Overview
Why calibrate? During operation, components of the P 700 IQ can age or become dirty
and thus change their characteristics, e.g.:
• Flow-through cell
• LED
• Photo diodes
• Color reagent
Regular automatic or manual calibration procedures help you to recognize any changes of the measuring characteristics of the P 700 IQ.
When to calibrate? Calibrate at regular intervals.
1-point calibration The offset of the characteristic curve can be adjusted with a regular 1-
point calibration.
The 1-point calibration can be carried out automatically at regular intervals. An additional 1-point calibration procedure can be started in the
calibration and service menu at any time. See section 4.2.2, 55.
54 ba76133e01 09/2013
Page 55
P 700 IQ
2-point calibration The current slope and the offset of the characteristic curve are adjusted
with a 2-point calibration.
2-point calibration with two different standards can only be started manually from the calibration and service menu. See section 4.2.3, 58.
Calibration record /
calibration history
The result of a calibration procedure is stored in the calibration record
and calibration history and can be viewed afterwards (see the relevant
ENSORNET system operating manual).
IQ S
Maintenance condition During the calibration procedure the P 700 IQ is in the so-called main-
tenance condition. All linked outputs remain in their current status. After
a manual calibration has been finished the maintenance condition has
to be switched off manually. More detailed information on the maintenance condition is given in the respective IQ S
ENSORNET system oper-
ating manual.
Calibration steps Each calibration procedure takes place in several steps:
1 Draw calibration standard and rinse the measuring circle with cal-
ibration standard
2 Measure the absorbance of the calibration standard without
reagent (blank value)
3 Add the reagent
Automatic
1-point calibration
Manual
1-point calibration
4 Leave to react for the reaction time
5 Measure the absorbance of the calibration standard with reagent
4.2.2 1-point calibration
1-point calibration is carried out automatically at regular intervals during
the measuring operation.
The settings for the calibration interval and calibration time are done in
the menu of the sensor settings.
The standard used for automatic 1-point calibration is identified automatically. The following standards can be used for automatic 1-point
calibration: ST 1.6, ST 8.0, ST 20.0.
Setting the calibration time and calibration interval (see chapter 4.1.4
Settings for the P 700 IQ, 51).
1-point calibration can be started as a manual calibration procedure as
necessary at any time. The calibration procedure is started and the
standard to be used is set in the calibration and service menu. The fol-
ba76133e01 09/2013 55

P 700 IQ
lowing standards can be used for manual 1-point calibration: ST 0.0,
ST 1.6, ST 8.0, ST 20.0.
Proceed as follows to carry out a 1-point calibration procedure manually:
A manual 1-point calibration with the same calibration standard used for automatic calibration can be carried out without opening the enclosure.

4.2.5 Reactivating the last valid calibration
If a manual calibration procedure is unsuccessful, the measuring operation can only be resumed after the manual calibration was repeated or
a valid calibration was reactivated.
If an automatic calibration procedure is unsuccessful, the analyzer
stops. To be able to measure again, you have to carry out a valid calibration procedure in the calibration and service menu, or to reactivate
a valid calibration.
Thus you can immediately continue to measure if a calibration failed or
you suspect that the calibration conditions were not optimally met.
Reactivating old calibration data is a temporary measure.
Take into consideration that the sensor my provide wrong
measured values. Ensure the correct functioning of the
sensor by checking and/or recalibrating it.

5.4 Carrying out the maintenance and cleaning activities
5.4.1 Changing the liquid containers
The P 700 IQ has an extra counter for each liquid container (from software version 2.13). The counter counts the consumption of the following procedures as soon as the function was started:
• Measuring
• Calibrate
• Cleaning
Other procedures that consume liquids are not counted (e.g. rinsing,
filling).
The current status of the counters for the liquid containers
can be output as log book messages (sensor settings /Sta-
tus (P700IQ-PO4) /Transmit to log book).
The counter displays the remaining quantity as a percentage.
If the remaining quantity of a liquid is only approx. 10% of the capacity,
a log book message is automatically issued.
The filling level can only be displayed correctly when the
new container is full (filling level 100 %).
Replace the container before the liquid is used up.
Maintenance interval Approx. 4 months,
depending on the frequency of measurement, cleaning, calibration.

5.4.4 Changing the pump tube of the peristaltic pump
How it functions The liquids are pumped through the P 700 IQ with the aid of a peristaltic
pump.
A peristaltic pump is a displacement pump for the pumping of liquids.
The liquid is in a flexible tube that is fitted in a circular pump housing. A
rotor with several rolls presses down some parts of the flexible tube.
When the rotor is turning, the rolls forward the liquid through the tube.
• The pump tube has a working life of 1500 hours for water. The
chemicals used may, however, reduce the working life.
• The deterioration of the tube quality is a slow process. When the
working life of the pump tube is near its end, the P 700 IQ may have
to be calibrated more often.
• A peristaltic pump can be blocked when it was not used for a longer
period of time, because the parts of the flexible tube that are pressed
down stick together. After a shutdown of several weeks the blockage
is normally cleared after some rotations. After a shutdown of several
months the flexible tube has to be removed and the blockage
cleared by hand.
Maintenance interval 12 months
Parts required • Pump tube PT (see chapter 7. Technical data, 99)
• Mounting aid
Preparations 1 Carry out the steps 1…11 in section 5.3.4 Maintenance and
cleaning work on the open P 700 IQ, 73.

29 Carry out the steps 13… 20 in section 5.3.4 Maintenance and
cleaning work on the open P 700 IQ, 73.
30 Make sure that the liquids run through the tubes in the correct
direction and that all tube connections are tight.
5.4.5 Cleaning the filter membrane
The time when to clean the filter membrane can be determined empirically based on the negative pressure display on the filtration pump.
• A pulsing negative pressure manometer suggests a normal operating condition of the filtration unit
• With a delivery height of approx. 2 m and a new filter membrane, the
negative pressure is approx. -0.3 bar.
Every meter of delivery height increases the negative pressure by
approx. -0.1 bar.
If the negative pressure increases by a further -0.3 ... -0.4 bar with
time, the membrane is covered with solid matter from the sample
and has to be cleaned.
• If there is still negative pressure after cleaning, the suction line may
possibly be blocked
The mechanical or chemical cleaning of the filter membrane may take some time.
Use a replacement filter unit (FM) during the cleaning process to keep the downtime of the analyzer as short as possible.
Prior to starting the cleaning process, switch off the filtration pump (with
the Start/Stop key, or switch off the whole analyzer).
88 ba76133e01 09/2013
Page 89
P 700 IQ
ATTENTION
Do not dismount the membrane insert from the PVC
enclosure, as the membrane surface adheres to the
seals and is normally damaged when dismounted. If the
membrane insert is removed it must be replaced.
The filter membrane is easily damaged. Never touch the
membrane with sharp-edged objects or place any
objects on it.
Pressure on the filter membrane must only be applied
from the outside. No counterpressure may build up
through the suction line.
The filter membrane can be cleaned either mechanically or chemically.
Prior to removing or plugging the sample tube, clean it e.g.
with clear water and a cloth.
Dirt particles in the sample flow can block the valves of the
photometer unit.
Maintenance interval 2 to 4 weeks, depending on application
5.4.5.1 Mechanical cleaning
Preparations 1 Carry out the steps 1…11 in section 5.3.4 Maintenance and
cleaning work on the open P 700 IQ, 73.
2 Switch off the filtration pump (with the Start/Stop key, or switch off

3 Pull the filtration unit out of the basin or channel.
• The filter module does not have to be separated from the
guide slide!
• Do not dismantle the membrane insert from the PVC enclosure!
4 Rinse off any gross contamination with low water pressure (e.g.
with a watering can or wash bottle).

5 Then carefully remove the coating from the filter membrane using
a soft special brush. Normally the brownish coating can well be
seen coming off while the lighter membrane surface is appearing.
ATTENTION
Do not press the special brush too firmly on the membrane surface and do not change the moving direction of
the brush (do not scrub!).
6 After cleaning, check both sides of the membranes for damage.
