1.3 Warning and safety information
The TitroLine® 7500 KF corresponds to prot ection cl ass II. It was manuf actured and tested according to DI N
EN 61 010, Part 1, Protective Measures for El ectronic Measurement Devices and has left the fact ory in an
impeccabl e condition as concerns safet y technology. In order t o maintain this condi tion and to ensure safe
operation, the user should observe the notes and warning information contained in the present operating
instructi ons. Development and production i s done within a system which meets the requi rements lai d down in
the DIN EN ISO 9001 standard.
For reasons of saf ety, the ti trat or TitroLine
®
7500 KF must be open ed by aut hori sed person s only; thi s means,
for instance, that work on electrical equipment must only be performed by qualified speciali sts.
In the case of nonobservance of t hese provisions the titrator TitroLine® 7500 KFmay co nstitute a
danger: electrical accidents of persons or fire hazard. Moreover, in the case of unauthorised
intervention in the titrator TitroLine
®
7500 KF as well as in the case of negligently or deliberately
caused damage, the warranty will become void.
!
Prior to switchi ng the dev ice on i t has to be en sured that the operati ng v oltage of the t itrator TitroLine® 7500
KF matches the mains voltage. The operating voltage is indicated on the specification plat e. Nonobservance of
this provision may result in damage to the titrator TitroLine® 7500 KF or in personal injury or damage to
property.
If it has to be as sumed that safe oper ation is im possible, the tit rator TitroLine
®
7500 KF has to be put out of
operation and secur ed against inadvertent putting to operation. In this case please switch the t itrator TitroLine
®
7500 KF off, pul l plug of the mains cabl e out of the mains socket, and rem ove t he titrator TitroLine
®
7500 K F
from the place of work.
Examples for the assumption that a safe operation is no longer possible,
the package is damaged,
the titrator TitroLine
®
7500 KF shows visible damages,
titrator TitroLine
®
7500 KF does not function properly,
liquid has penetrated into the casing.
The titrator TitroLine
®
7500 KF must not be stored or operated in humid rooms.
For reasons of saf ety, t he tit rator TitroLine
®
7500 KF m ust onl y be used f or the range of appl i cation descri bed
in the present operati ng instructions.
In the case of dev iations from the intended proper use of the device, it is up to the user to evaluate the
occurring risks.
!
T he relevant reg ulations reg arding the h andling of th e substan ces used have to b e observed: The
Decree on Hazardou s Matters, the Chem icals Act, and the rul es and inform ation of the chemical s trade. It
has to be ensured on t he side of the u ser that the persons entr usted with the u se of the titr ator TitroLine
®
7500 KF are experts in the handli ng of substances used in the envir onment and in titrat or TitroLine
®
7500 KF
or that they are supervi sed by speci alised persons, respectively.
During all work with tit r ation solutions:
!
Please wear protective gl asses! !
The titrator TitroLine
®
7500 KF i s equipped with int egrated circuit s (EPROMs). X rays or other high energy
radiation may penetrate through the device’s casing and del ete the program.
For working with liquids, not beeing common titration solvents, especially the chemical resistance of the
construction m aterials of the t itrator TitroLine
®
7500 KF hav e to be considered (pl ease also refer to chapter
1.1).
For the use of liqui ds with hi gh vapour pressure or (mixture of) substance s not being m enti oned in chapt er 1.1
as allowed substances, t he safe and proper op erati on of the tit rator TitroLine
®
7500 KF has to be guaranteed
by the user.
When the piston moves upwards withi n t he cyli nder, a mi crofilm of dosing li qui d or titrati on solution wil l al ways
remain adhered to t he inner wall of the c ylinder, but t his has no i nfluenc e on the dosing acc uracy. T his small
residue of li quid, however, may ev aporate and t hus pe netrat e i nto t he zone underneat h the piston, and if nonadmitted liqui ds are being used, the m aterials of t he titrator TitroLine
®
7500 KF may be dissolved or c orroded
(please refer al so to c hapter 8 “Maintenance and Care of the titrator Titr oLine
®
7500 KF”).

Each time an interc hangeable unit is pushed onto the base unit, t he data is automatically read out of the
transponder.
2.6.1 Placing an interchangeable unit
The interchangeabl e unit is to be placed on the device unit as is shown in fig. 12 a-c; subsequentl y , it is to be
pushed downwards until the black button latches on the left side.

2.6.2 Remo ving an interchangeable uni t
Removing the int erchangeable unit is done in reverse order:
• Depress the black button on the left, and then pull the interchangeable unit forward as is shown in fig. 12
c – 12 a.
!
Please note: Removing the interchangeable unit is only possible as long as the piston is in the lower
position (zero position). Possibl y, i t may be necessary to press the <FILL> key first.

2.6.3 Programming the titration unit
The data from the RFID transponder of the interchangeable uni t will be read immediately (fig. 13).
Fig. 13
Following the reading operation, the input menu for the input of t he r eagents will be shown for approx. 10
seconds (fig. 14). The size of the interchangeable unit is displayed on the left side of the display (here 10 ml).

Chapter 2. Unpacking and F ir s t O per ation
When used for the first time, it is recommended to enter here at least the name of the reagent being used. To do
so, confirm the “Reagent “selection with <ENTER>, then ty pe the name and possibly the concentrati on (fig. 12).
Fig. 15
Press <OK>/<ENTER> to confirm (fig. 15). Following the optional input of additional parameter, press <ESC> to
leave the reagent s menu (fig. 16). The approximate concentrati on of t he KF tit r ant (e.g. 5 or 2) should be entered
under concentration. Thereby the drift in µg/min can be calc ulated in the right dimensions.
Fig. 16
You will be prompted for a confirmation of the values (fig. 17):
Fig. 17
If you selected <Yes>, the values will be written into the interchangeable unit. You can see this from a message
in red colour displayed at the bottom. Upon completion, the lef t bot tom corner of the display will show the new
name of the reagent (fig. 18). In t he pr esent c ase this is Titrant 5.

2.7 Initial Filling or Rinsing of the Entire Interchangeable Unit
Initial filli ng of the interchangeable unit is done using the <rinsing > rinsing programme.
Fig. 19
On the main menu (fig. 19), press <MODE> key to navigate t o the methods/system (fig. 20).
Fig. 20
Pressing <↑> twice will take you to the <Rinsing> selection immediately (fig. 21).

Confirm the selection by pressing <ENTER>:
Fig. 22
At this point you can selec t t he num ber of rinsi ng cycl es (Fig. 19). I ni tial f illing r equir es a m i nimum of two rinsi ng
cycles. You can stop t he rinsing operation (F ig. 20) at any tim e by pressing <STOP> and then resume ri nsing
with <START>.
Fig. 23
While the i nitial filling or ri nsing programme is being run, pl ease place a suffic iently dimensioned waste v essel
under the titration tip. The best is when the titration tip is mount ed in the KF titration vessel.

2.8 Filling the titration vessel with solvent
The solvent is pumped from the solvent bottl e into the titration v essel by pushi ng down the front part of the rocker
switch on the titration stand TM 235 KF. Pump solvent into the titration vessel until the titration tip and the
electrode are c om pletely immersed. This will be approx. 35-40 ml of solvent:

2.9 Replacing the Glass Cylinder and the PTFE Piston
Replacing the glass cylinder and the pi ston does not require any additional tools. In certain cases the piston
extractor has to be used.
• Remove the interchangeable unit from the base unit.
• Unscrew the hose between the glass cylinder and the valv e from the glass cylinder.
• Rotate the blue UV protection 5 to 6 times to the left t o loosen it.
• You can r em ov e the UV protection and pull out of the glass cylinder toget her with the piston inside it.
• Insert a new glass cyl inder and piston (F ig. 25) into the i nterchangeable uni t, and then sli p on the blue
UV protection again.
• Tighten the blue UV protection again by rot ating it 5 to 6 times to the right.
• The pi ston rod shoul d proj ect 1-2 cm out of the interchangeable uni t (Fi g. 26 a). At thi s point , til t t he unit
forward unt il the slant ed bott om side is in fl at c ontact wit h the lab t able (Fig. 26 b). This forc es the piston
into its correc t position. Should the piston be f orced som ewhat t oo far into the glass cylinder, simply pull it
out and place it in the correct position according to the procedure descri bed above.
