Overview MPP 9x0 IDS

1Overview
The MPP 9x0 IDS multi-parameter probe is a modular system, consisting of
a basic module and various expansion options.
System
components
(figure see page
on the right)
Depth
measurement
On the shaft of the basic module there is a pressure sensor with integrated
temperature measurement. Based on the pressure and temperature value
the meter calculates the depth of immersion in the measuring medium. The
temperature measurement is used for the temperature compensation of the
pressure sensor and for density compensation.
1Basic module MPP 910 IDS with one sensor plug-in position
2Basic module MPP 930 IDS with three sensor plug-in positions
3AS/IDS-xx connection cable between basic module and meter or sen-
sor and meter (xx = different lengths available)
4Blind plug BPO/IDS 900 for cable plug-in position
Expansion options:
5Digital sensors of the XXX-P series, e.g. FDO 925-P
6BPI/IDS 900 blind plug for BPI/IDS 900 sensor plug-in position
7Long protective tube, to protect the sensors connected
8Short protective tube, for usage of the basic module without any sen-
sors. Reduces the distance between the depth/temperature sensor
and the bed of the water body

Overview MPP 9x0 IDS

IDS plug
connection
All plug connections of the basic module, sensors, connection cable and blind
plug are of the same type. A lock protects the connections against being inad-
vertently disconnected.
With the connection cable, the individual sensors can also be directly
connected to the meter if necessary (for calibration or firmware update).
Recommended
fields of
application
On-site measurements in rivers, lakes, sea water and brackish water,
wells, leachate that is not or only slightly polluted
Measurements in boreholes
Depth profile measurements
Measurements in ground and spring water

2 Operation
2.1 Opening and closing the plug connections
The following instructions apply to all actions where any components are con-
nected or disconnected (e.g. exchange of blind plug ⇌sensor):
Opening the plug
connection
If necessary, clean the plug connection
Open the locking device (step 1)
Use your thumb and index finger to press the clips of the connector
together, and pull the connector out of the plug (step 2).
Closing the plug
connection
Make sure that the plug connection is completely dry and clean.
Align the guidance of the connector with the groove in the plug and insert
the connector in the unlocked plug until it catches (step 3).
Close the locking device (step 4).

Operation MPP 9x0 IDS

NOTE
All plug-in positions have to be equipped with sensors or closed with
blind plugs before the multi-parameter probe is immersed in the
measuring medium.
2.2 Commissioning
Prepare the sensors for the measuring operation (see sensor operating
manual). For calibration, connect the sensors to the meter with the 1.5 m
connection cable.
Equip the basic module with the required sensors:
– Unscrew the short protective pipe
– Per plug-in position:
Replace the blind plug with a sensor (depending on the required
design, how to do this is described on page 7).
– Screw on the long protective pipe
Screw the sinker on the open end of the protective pipe so the probe will
go down faster.
Connect the basic module to the meter.
NOTE
The connection cable without any problems withstands the tractive
forces that occur when it is pulled by hand in a water body where there
are no strong current and no obstacles. If the current is strong or if
there are obstacles the tractive forces can temporarily be much higher
and cause the cable to snap. If you are in doubt we recommend to
attach the multi-parameter probe with the holding shackle (accesso-
ries) to a sufficiently strong rope or a chain so the probe will not be lost.
NOTE
All plug-in positions have to be equipped with sensors or closed with
blind plugs before the multi-parameter probe is immersed in the
measuring medium.
Calibrating the sensors while they are installed is not possible.
The depth and temperature measurement of the basic module is
calibration free (factory calibration).

2.3 Mounting the holding shackle
The holding shackle is screwed onto the sensor instead of the protective ring.
To do so, proceed as follows (sample figure of MPP 930 IDS):
Disconnect the connection cable from the basic module (see page 7)
Unscrew the protective ring (pos. 1).
Thread the connection cable through the connecting piece of the holding
shackle (pos. 2) and reconnect it to the basic module
Screw the holding shackle to the basic module

Cleaning MPP 9x0 IDS
10 ba75981e02 12/2017
3 Cleaning
Exterior cleaning Remove water-soluble contamination by rinsing with deionized water. Other
types of contamination have to be removed as follows while the contact time
with the detergents should be kept as short as possible:
Thoroughly rinse the multi-parameter probe with water after this.
Cleaning the
pressure sensor
To clean the pressure sensor, remove the screen lid with your fingernails.
Then rinse the recess with a mild water jet (e.g. wash bottle or slightly-
running faucet).
NOTE
The membrane of the depth sensor is very sensitive to mechanical
impacts. Therefore, avoid any touching of the membrane. Do not point
a sharp water jet at the membrane while cleaning it.
Please observe the instructions on cleaning the sensors given in
the respective sensor operating manuals. If necessary, remove
the sensor for cleaning and close its plug-in position with a blind
plug.
Contamination Cleaning procedure
Fat and oil Rinse with water containing household wash-
ing-up liquid
Lime and hydroxide deposits Rinse with citric acid (10 % by weight)
