Introduction
The TitraLab 840 and 845 Titration Workstations are dedicated for routine use. They offer two
distinct user levels:
• Supervisor
Dedicated for operators who wish to edit their methods to fit their specific needs. They can
also assign a password to protect the programmed data from eventual changes.
•Routine
Dedicated for operators wishing to use the routine functions to guide them step by step
through the analyses.
The TIM840 and TIM845 can store up to 10 methods, 15 electrodes and 15 reagents.
Thanks to the preprogrammed applications, the Titration Manager is ready for use as soon as
it has been installed. Refer to "Appendix 1: Preprogrammed methods", page 199.
The TIM840 and TIM845 also allow you to automatically sequence and repeat measurements
- ideal for direct measurements followed by a titration.
The purpose of the TitraLab 840 and 845 Reference Manual is to give detailed information on
the Titration Workstation and the data displayed during operations. The information is listed in
alphabetical order for quick access and cross-references are listed in italics.
In addition to this handbook, a general User’s Guide (part no. D21T065) is available giving
descriptions and overviews of the workstation menus and operating concepts to guide you
through programming and running of the analyses.

General Information
Safety Information
Please read this entire manual before unpacking, setting up, or operating this equipment.
Pay attention to all danger and caution statements. Failure to do so could result in serious injury
to the operator or damage to the equipment.
To ensure that the protection provided by this equipment is not impaired, do not use and do not
install this equipment in any manner other than that specified in this manual.
Precautionary Labels
Read all labels and tags attached to the instrument. Personal injury or damage to the
instrument could occur if not observed.
This symbol, if noted on the instrument, references the instruction manual
for operation and/or safety information.
Electrical and electronical equipment marked with this symbol may not be
disposed of in European public disposal systems after 13 August of 2005.
In conformity with European local and national regulations (EU Directive
2002/96/EC), European electrical equipment users must now return old
or end-of life equipment to the Producer for disposal at no charge to the
user.
Note: For equipment supplied or produced by "Radiometer Analytical",
please contact www.hach-lange.com and select your country for instructions on how to return your equipment for proper disposal."
This symbol, when noted on the product, identifies the location of a fuse
or current limiting device.
Warning!
The TitraLab 840 and 845 have been developed to meet the requirements of volumetric
titration applications. It is therefore aimed at experienced users who have the knowledge
required to operate the instrument and implement the security instructions enclosed.
Please remember that the Titration Manager must not, under any circumstances, be used
to perform tests on living beings.
We accept no responsibility for using theTitration Manager and its peripheral
devices under conditions that are not specified in this Reference Manual and its associated
User’s Guide (part no. D21T065).

Starting up instructions
Set up the instrument in a properly ventilated place. The power supply connector on the rear
panel must remain accessible and close to the user (2 m maximum) so that you can quickly
disconnect the cables in case of emergency.
The room temperature must be between 5 and 40°C.
The relative humidity must be between 20 and 80°C.
To a mains supply socket
Connect the mains socket of the Titration Manager to the mains supply using the 3-lead power
cord provided. The Titration Manager must be connected to an earthed mains socket for safety
reasons. Efficient grounding is essential for reliable measurements and security.
In the USA or Canada, use a UL listed power cord only.
Switch on the Titration Manager (O/I power switch set to "I")
The Titration Manager displays during a few seconds an identification screen (name and
embedded software version) followed by the Main window, see "Main window", page 83.

An important feature of this Titration Manager interface is that it controls the presence of different elements necessary to run the defined application for a selected method/sequence, before
the method/sequence is run.
Working in Supervisor mode
A Supervisor has access to all the libraries for creation purposes.
When programming the Titration Manager in “SUPERVISOR” mode, it is recommended to
work in stages. These stages must be carried out in the order described below:
A.To program method
1.Define your electrode(s)
Identify electrodes (including temperature sensors) to be used for the analysis:
Electrodes can be created from the following lists:
Catalogue, see "Catalogue list", page 56.
Other, see "Others list", page 128.
Copy from, see "Copy electrode", page 63.
When creating the electrode, define if electrode calibration is required (or not), if yes specify
the "periodicity" of the calibrations and the pH standards to be used. Refer to "Calibrate elec-
trodes", page 55.
2. Define reagent
Identify reagents to be used for the analysis
Reagents can be created from the following lists:
Catalogue, see "Catalogue list", page 56.
Other, see "Others list", page 128.
Copy from, see "Copy reagent", page 64.
When creating the reagent, define if reagent calibration is required (or titre entered manually),
if yes specify the "periodicity" of the calibrations and the calibration method. Refer to "Reagent
calibration", page 145.
If a sample changer is to be used, define the sample changer in the Configuration menu before
programming a SAC sequence.
If you are to perform a calibration, make sure that the electrode(s) used for the calibration are the same as those used in the method.

TitraLab 840 and 845 Reference Manual
3. Create new method or Edit a pre-programmed one
Create the measurement or titration method to be used for the analyses. Enter the parameters
required to calculate the results, see "Programming methods", page 25.
When you have finished programming, select the method or pre-programmed application, see
"Select method", page 175.
If you are using a sample changer, edit the sequence and program the sample stack, see
"Sample stack", page 174.
4. Check icons
The following icons indicate the exact state of your working system:
Sunny icon:
Everything is OK. Run the method or sequence.
Cloudy icon:
Electrode/reagent calibration required within 12 or 24 hours.
Stormy icon:
Electrode/reagent calibration date elapsed or reagent(s) not installed.
Question mark:
Programming error.
Refer to "Electrode icons", page 87.
Refer to "Reagent icons", page 149.
Sunny icons are needed in order to run the selected method.
If Cloudy/Stormy/Question mark icons are displayed in the Reagent/Electrode window
press 1 to activate the “Check” command. The Titration Manager will automatically
guide you through the operations required to solve the errors encountered.
B.Running methods
To run a method or sequence, see "Working in Routine mode", page 18.

When working in “ROUTINE” mode, it is necessary to install your titration system according to
the selected method or sequence, prior to running a method or sequence.
1. Select the method or sequence
Refer to "Select method", page 175.
Refer to "Select sequence", page 175.
2. Connect the electrodes
Refer to "Electrode connection", page 86.
3. Check icons
Refer to "Check icons", page 17.
Depending on the icons displayed, the Titration Manager will automatically guide you through
the steps necessary to run the analysis, see below:
a. Install reagents(s)
Check that the burette is installed, if not, see "Install burette", page 107.
Now, install the reagent, see "Install reagent", page 108.
b. Calibrate electrode(s)
Now, run the calibration, see "Calibrate electrodes", page 55.
c. Calibrate reagent(s) or Enter titre
Now, run the calibration or enter the titre.
Refer to "Reagent calibration", page 145.
Refer to "Enter titre", page 92.
d. Run the method or the sequence
Refer to "Running a method (preliminary steps)", page 162.
Refer to "Running a sequence with a sample changer", page 166.
