5 Electrical connection
The choice of cable, the installation, and the electrical connection
must conform to the requirements of VDE 0100 “Regulations on the
Installation of High-Voltage Systems with Nominal Voltages below
1000 V” or the appropriate local regulations.
❏ To protect the device from static electrical discharge, the user
must be electrostatically discharged before touching the
instrument!
❏ The electrical connection must only be carried out by qualified
personnel.
❏ Electromagnetic compatibility conforms to the standards and
regulations cited in the technical data.
❏ Operates only on SELV or PELV circuits.
❏ The instrument is not suitable for installation in areas with an
explosion hazard.
Apart from faulty installation, incorrect settings on the instrument
may also affect the proper functioning of the subsequent process or
lead to damage. Safety devices should always be provided that are
independent of the instrument (such as overpressure valves or
9
temperature monitors/limiters) and only capable of adjustment by
specialist personnel. Please observe the relevant safety regulations
for such matters.
❏ The load circuit must be fused for the maximum relay current, in
order to prevent the output relay contacts from becoming
welded in the event of a short circuit.
❏ The supply voltage must be fed into the instrument through a
125-mA fuse, medium time lag or comparable protection by
means of a separate branch.
❏ Do not connect any additional loads to the screw terminals for
the supply of the instrument.
❏ Any electrical connection deviating from the connection diagram
may cause the instrument to be destroyed.
❏ Lay the input, output, and supply lines so they are physically
separated from each other and are not parallel.
❏ Lay probe cables only as continuous lines, twisted and shielded
(not via series terminals or similar arrangements).
❏ Fluctuations in supply voltages are only permitted within
specified tolerances (see datasheet 20.2723).
❏ The instrument must not be mounted or dismounted unless it is
in dead state and/or the lines are not connected.
5.1 Connecting the sensor
To connect the pH redox electrode, special coaxial lines are
recommended as specified by JUMO datasheet 202990. Standard
commercial antenna or computer lines with coaxial construction are
generally not suitable. They may result in faulty readings or could
destroy the pH or redox electrode.
The semiconducting layer (see Fig. (2)) of the special coaxial line must
be at a sufficient distance to prevent a short circuit with the inner
conductor on the transmitter terminal. The coaxial line may be sensitive
to touch or motion due to the high internal resistance of a pH electrode.
This must be taken into consideration when laying the cable.

✱ Twist the shield (1) and insulate with a shrink tubing.
✱ Insulate the black semiconducting layer with shrink tubing (2) to
prevent short circuits.
✱ Place ferrules on the line ends.

6 Commissioning
6.1 Brief description of the instrument
The instrument measures and, depending on the configuration,
regulates the pH or redox voltage in aqueous solutions. The range
of applications includes general water and wastewater
management, measuring drinking and wastewater, process water,
surface and ocean water, swimming pool and fountain water, and
professional aquariums, etc.
The transmitter has two analog inputs. The first analog input (main
input for pH value or redox voltage) is provided for connecting
electrodes with an isolated reference electrode. The instrument is
also prepared for connecting antimony electrodes. A resistance
thermometer (Pt 100 or Pt 1000) can be connected to the second
analog input.
Up to two analog outputs and one relay switching contact are
available. The analog outputs are galvanically isolated and assigned
to the inputs. Either the main value (pH or redox voltage) or the
temperature can be assigned to the relay contact.
The keys and integrated LD display are used to operate and
configure the instrument. This can also be done very conveniently
with the setup connection (Notebook / PC) using the optional setup
program. The setup program can also be used to print configuration
data. This makes system documentation easier.
Instruments are delivered with a calibration verification tool that is
used to document instrument and calibration data.
With the correct wiring of device and sensor, and
correct configuration of the device, a measurement without calibration should be possible.
If this is not the case, influencing factors such as
short circuit, open circuit, EMC and flow conditions should also be considered.

.
1
(see Enable level).
parameters can only be read on the User level, not changed.
2
Codes for the Administrator and Enable levels can only be
changed with the setup program
(see Section 13 "Operation via setup interface", page 64).
7.3 Key function
After 60 seconds with no user activity (no keystrokes),
the display reverts to process value display.
This timeout function is not active during calibration!
- The UP and DOWN keys are used to select a submenu in the
main menu and to scroll forward and backward.
- The P key switches to the corresponding submenu.
- To change (edit) a parameter, press the P key.
- When the parameter is released for editing, the value flashes. If
the parameter is locked, "LOCK" appears in the display.
- To change the parameter, it must be unlocked on the Enable level
(changed from "rEAd" to "Edit").
18
- To increase or reduce the value, press the UP or DOWN key.
- The value can then be accepted with the P key.
- The EXIT key is used to cancel the entry and switch to the next
higher level.

8 Configurable parameters
Parameters can be set with the setup program or on
the instrument.
Since some parameters are independent of each
other, it may be necessary when one parameter is
changed to adjust others as well.
Example:
When the measurement variable is changed (from pH
to redox voltage or vice versa) the display format,
setpoints, and other parameters are adjusted.
While parameters are being adjusted internally, the
display appears as follows:

9 Calibration
9.1 General information
The zero point (intercept) and slope of pH sensors stray from copy
to copy. During the service life of the sensor, up to the time it must
be replaced by a new sensor, the zero point and slope change. To
allow for precise measurements, the transmitter must be adjusted
(calibrated) to the current sensor parameters. The calibration is
performed using buffer solutions.
Only the zero point needs to be calibrated for redox sensors.
9.1.1 When is calibration required?
The electrochemical sensors should be cleaned and the transmitter
should be calibrated at regular intervals (depending on the
measuring medium)!
With the correct wiring of device and sensor, and
correct configuration of the device, a measurement without calibration should be possible.
If this is not the case, influencing factors such as
short circuit, open circuit, EMC and flow conditions should also be considered.
9.2 Activating and starting calibration mode
During the calibration process, the display flashes.
The analog outputs respond as they were calibrated
on the USER LEVEL / ANALOG OUTPUT x /
FOR CALIBRATION.
The response of the relay depends on the
configuration of the switching output!
40
Calibration can be cancelled at any time with the EXIT

key. Old calibration data will not be lost
.
Calibration is performed using the instrument keys.
The zero point and slope of a sensor can also be
entered manually. This should only be done in
exceptional cases. Some sensors come with a test
report that specifies the zero point and slope. These
values simply provided documentation that the
sensor was in proper condition upon delivery. Since
these values change during storage, they are not
suitable for manual entry. We always advise
performing calibration with buffer solutions.
The timeout function is not active during calibration!
9.2.1 Starting calibration from the calibration level "CALIB"
Use the menu to switch to the calibration level (see
Section 7.4 "Selecting levels", page 20 and Section
7.8 "Calibration level (CALIB)", page 24).

9.3 Canceling calibration and error messages
Calibration can be cancelled at any time with the EXIT
key. Old calibration data will not be lost
During the calibration process, the transmitter calculates the
electrode parameters zero point and if applicable slope. If the
calculated values fall outside the permissible parameter limits, an
error message is generated.
For the permitted value ranges of parameters NULL and SLOPE see
Section 8.1.1 "Measurement input - main value (submenu "PH")",
page 26.

or the two calibration points Ref.1 and Ref.2 are too close to each
other.
For two-point calibration of a pH sensor, the minimum spacing is
2 pH.
For two-point calibration of a redox sensor, the minimum spacing is
2 mV.
The greater the spacing, the more accurate the calibration.
9.3.4 Acknowledging errors
✱ Press the keys or EXIT.
The error message is deleted.
The faulty parameters NULL and/or SLOPE are not saved.
The instrument continues working with old calibration data.
9.3.5 Additional measures
✱ Check the quality and condition (age) of the buffer solutions.
✱ Check whether the sensor is dirty or needs to be replaced.
✱ Check whether the sensor plug is moist or the wiring is faulty.
✱ Observe the minimum spacings for buffer or reference values.
9.4 One-point or two-point calibration
For one-point calibration, the transmitter is only adjusted to the zero
point of the sensor.
In two-point calibration the transmitter is adjusted to both the zero
point of the sensor and its slope. We expressly recommend twopoint calibration!

accordingly; see Section 8.1.2 "Measurement input temperature (submenu "TEMP")", page 28.
12.5 Short-circuit
12.6 Initialization of dependent parameters
After a parameter has been changed, other dependent parameters
are automatically changed.
Please check all dependent parameters!
12.7 Calibration timer elapsed
Depending on specifications (for example of the equipment
manufacturer), calibration of the measurement chain should be
performed.
After a correct calibration, the calibration timer is reset and
automatically restarted.
