Introduction

1 Introduction

Simple and compact

The AQUASTAR® Compact Titrators are modern, titrators for use in a wide variety of application areas.
They can be used, for example, in quality control as well as in research and development and satisfy the
most demanding of requirements.

The AQUASTAR® titrators perfectly combine simple, easy-to-understand operation with an extremely high
lev el of precision and outstanding reliability. Thanks to automatic titrant recognition (Plug & Play bu­rettes), the titrator independently identies which titrant is required without intervention from the oper a tor.
Settings no longer need to be adjusted manually, even when connecting a printer.

The instruments can either be controlled by Touchscreen or by using LabX PC software. The large color
Touch screen allows intuitive control by the user and exibility in its adjustment options. All functions can
be activated directly from the Homescreen via Shortcuts which can be freely created, making everyday
use extremely easier. Controlling the titrator by Touchscreen and all adjustable parameters are described
sep a rate ly and in detail in the operating instructions on the Tutorial CD.

This installation information explains all the steps necessary for installing and commissioning your de­vice. The "Quick Guide" will then guide you through the rst titration process using a practical exam ple. If
you have any additional questions, EMD is always available to assist you.

Measures for your protection

2 Measures for your protection

The instruments have been tested for the experiments and intended purposes documented in the appro­pri ate Operating Instructions. However, this does not absolve you from the responsibility of performing
your own tests of the products supplied by us regarding their suitability for the methods and purposes
you intend to use them for. You should therefore observe the following safety measures.

Measures for your protection

Risk of electric

shock

Risk of explosion

●

Only use the power supply unit that was included with the instrument.

●

Ensure that you plug the power cable supplied into a receptacle outlet that is
ground ed. In the absence of grounding, a technical fault could be lethal.

●

Never work in an environment subject to explosion hazards! The housing of
the instrument is not gas tight (explosion hazard due to spark formation, cor­ro sion caused by the ingress of gases).

●

Always test the titration vessel for rm seating in the titration head. If it falls off,
you could injure yourself if working with toxic titrants and solvents or strong

acids or bases.

●

Risk of corrosion

When using chemicals and solvents, comply with the instructions of the pro­duc er and the general lab safety rules!

All Karl Fischer reagents are readily ammable and toxic.

●

In the case of skin contact, immediately wash off with copious amounts of wa­ter!

●

If eye contact occurs, rinse intensively with copious amounts of water and
con sult a physician!

Measures for your operational safety

●

Have the instrument serviced only by METTLER TOLEDO Service!

●

Any spillage should be wiped off immediately! Some solvents might cause cor­ro sion of the housing.

Caution

●

Exclude the following environmental inuences:

•

Powerful vibrations,

•

direct sunlight,

•

atmospheric humidity greater than 80%,

•

temperatures below 5 °C and above 40 °C,

•

powerful electric or magnetic elds!

Installation (components)

5 Installation (components)

Installation for all titrator types is described in this chapter. Standard equipment for the various types of
titra tors varies and also depends on the optional accessories. For this reason, installation steps may
vary.

5.1 Connecting the power supply

The titrator is operated by a separate power supply. The On/Off switch is tted with an LED and mounted
on the front of the titrator. The LED displays the operating status. The titrator is switched on by pressing
the On/Off button. The LED ashes as the system starts up and then remains permanently lit. The titrator
is switched off by pressing the On/Off button again. All current tasks are interrupted and the LED starts to
ash until the system has shut down, which can take up to 60 seconds. The LED then goes out.

a) Connect the power supply unit to the "POWER SUPPLY" socket on the rear of the titrator and to the

mains supply.

b) Secure the connection at the titrator by screwing the plug connector rmly into place.

The power supply is suitable for all supply voltages ranging from 100–240 VAC ±10% and 50–60 Hz.

Power Management

The devices have a power management system which prevents the titrator from switching off unex pect­ed ly in the event of a power overload. Tasks which would cause a power overload, because a number
of pumps, stirrers and burette drives are already in use, cannot be started at all. A notication brings the
start attempt to the attention of the user. It is advisable, if possible, to connect pumps and stirrers direct­ly to sample changers or other devices which have their own power supply, such as a TBox, instead of to
the titrator itself.
