Section 2 General Information
2.1 Safety information
Please read this entire manual carefully before unpacking, setting up, or operating this
equipment. Pay attention to all danger and caution notices. Failure to do so could result in
serious injury to the operator or damage to the equipment.
To prevent damage to or impairment of the device's protection equipment, the device may
only be used or installed as described in this manual.
2.1.1 Hazard notices in this manual
Note: Information that supplements points in the main text.
2.1.2 Precautionary labels
Read all labels and tags attached to the instrument. Personal injury or damage to the
instrument could occur if not observed.
DANGER
Indicates a potentially or imminently hazardous situation that, if not avoided, can result in death or
serious injury.
WARNING
Indicates a potentially or imminently dangerous situation that, if it is not avoided, can lead to
death or to serious injuries.
CAUTION
Indicates a potentially hazardous situation that may result in minor or moderate injury if it is not
avoided.
NOTICE
Indicates a situation that, if it is not avoided, can lead to damage to the device. Information that
requires special emphasis.
This symbol, if noted on the instrument, references the instruction manual for operation and/or safety
information.
This symbol may be found on an enclosure or barrier within the product and indicates a risk of electric shock
and/or death by electrocution.
Electrical equipment marked with this symbol may not be disposed of in European domestic or public disposal
systems after 12 August 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
manufacturer for disposal at no charge to the user.
Note: Please contact the equipment manufacturer or supplier for instructions on how to return end-of-life
equipment, manufacturer-supplied electrical accessories, and all auxiliary items for recycling or proper disposal.

General Information
2.2 Overview of product
The TSS Portable is a handheld measurement instrument for the analytical determination
of turbidity and solids in aqueous media.
2.3 Measurement instrument
The instrument stores the recorded data under the corresponding calibration curve. Four
calibration curves for solids (C-DS1, C-DS2, C-DS3, C-DS4) and one calibration curve for
turbidity (C-TU) are available for selection.
For solids measurements, a specific calibration must be assigned to each measurement
point (section 5.1, page 23).
All measurement values are saved with details of the selected calibration curve, the
measurement value, the homogeneity, the date and the time.
Various individual parameters for input, signal processing and output can be set in the
menu (Section 4, page 15).
2.4 Measuring principle
The measuring principle is based on a combined infrared absorption stray light process,
which determines the lowest turbidity value according to DIN EN 27027 just as precisely
and continuously as the high sludge content. In so doing, the light scattered sideways by
the turbidity particles is measured at an angle of 90°. In the case of solid material, the
measurement occurs at an angle of 90° and 120°.
2.5 Probe
The probe contains sensitive optical and electronic components. Care must therefore be
taken to ensure that it is not subjected to any hard mechanical impacts. The inside of the
probe, and of the display unit, does not contain any components that can be serviced by
the user.

Section 3 Installation
3.1 Product contents
After taking the instrument out of the case, check each part for damage. All the
components on the enclosed list must be present. If any parts are missing or damaged,
please contact the manufacturer or the distributor.
WARNING
Risk of falling. Measurements are taken directly on site with this instrument. In order to avoid
falling into the basin, all local safety regulations with respect to roping up and wearing appropriate
protective clothing and shoes must be observed.
Risk of injury. Do not secure the instrument to your body. The measuring probe may catch
unintentionally on a slide or stirrer and the connected probe cable may put the user at risk.

Installation
3.2 Powered via rechargeable batteries
The instrument is operated by six rechargeable NiMH batteries (Figure 2).
3.2.1 Inserting the rechargeable batteries
1. Press in both catches at the same time and release the cover.
2. Take the battery holder out of the battery compartment (Figure 2).
3. Insert the delivered six rechargeable NiMH batteries into the battery holder. Take note
of the markings for the polarity.
Note: Make sure that the rechargeable batteries have been inserted into the battery compartment
correctly.
4. Connect the battery holder to the battery clip.
5. Push the battery holder into the battery compartment.
6. Push the cover onto the battery compartment until it audibly engages in the catches.
WARNING
Risk of fire and explosion. Only use rechargeable NiMH batteries and ensure that the
rechargeable NiMH batteries are inserted correctly in the battery compartment. Incorrect insertion
of the rechargeable NiMH batteries may damage the instrument or lead to fire or explosions.
WARNING
Risk of fire and explosion. When using not rechargeable AA batteries, the not rechargeable
batteries could explode if the instrument is connected to the charger. Only use rechargeable
NiMH batteries from the manufacturer of the instrument.
NOTICE
Remove the rechargeable NiMH batteries if the instrument is not to be used for a period of time.
Only use rechargeable NiMH batteries from the manufacturer of the instrument.
