1.4 User qualification
Carrying out photometric determinations with the aid of test sets frequently
requires the handling of hazardous substances.
We assume that the operating personnel know how to handle hazardous sub-
stances due to their professional training and experience. The operating per-
sonnel must particularly be able to understand and correctly implement the
safety labels and safety instructions on the packages and inserts of the test
sets.
1.5 Handling of hazardous substances
For the development of test sets, Tintometer pays close attention to as safe
an execution as possible. Some hazards by dangerous substances, how-
ever, cannot always be avoided.
If self-produced tests or solutions are used, the responsibility concerning any
risks caused by those tests or solutions lies with the user (personal respon-
sibility).
WARNING
Improper handling of certain reagents can cause damage to your
health.
In any case follow the safety labels on the packing and the safety in-
structions of the package insert. Protective measures specified there
have to be followed exactly.
Safety datasheets The safety datasheets of the chemicals comprise all instructions on safe han-
dling, occurring hazards, preventive actions and actions to take in hazardous
situations. Follow these instructions in order to work safely.

Packing This photometer is sent out in a protective transport packing.
CAUTION
Keep the original packing including the inner packing to protect the in-
strument against hard shocks if it has to be transported.
The original packing is also required for the proper return of the instru-
ment if it has to be repaired.
Note that damage caused by improper transport voids all warranty
claims.
3.2 General notes on handling
Always protect the meter from conditions that could damage the mechanical,
optical and electronic components. Heed the following points especially:
The temperature and humidity during operation and storage must be
within the limits specified in Chapter 7 TECHNICAL DATA.
The following influences always have to be avoided with the meter:
– Extreme dust, moisture and wetness
– Exposure to intensive light and heat
– Fumes that are corrosive or contain high concentrations of solvents.
For measuring, the meter must be placed on a flat surface.
Spilled liquid or other material should be removed immediately (see Sec-

Commissioning XD 7500
16 ba77191e01 - 71310060 04/2018
tion 5.2 CLEANING or Section 6.1 ACTIONS IN THE CASE OF ABROKEN CELL).
The cell shaft should always be closed when the photometer is not used.
For the instrument to be transported the cell shaft has to be empty.
For mobile use, we recommend the transport case (item no. 71310010,
see Section 8.1 ACCESSORIES).
3.3 Initial commissioning
Perform the following activities:
Insert the buffer batteries (see Section 3.3.1)
Connect the power supply (see Section 3.3.2)
Switch on the photometer (see Section 3.3.3)
Set the language (see Section 3.3.4)
Set the date and time (see Section 3.3.5)
Carry out a zero adjustment (see Section )
3.3.1 Inserting the buffer batteries
Four buffer batteries (type AA or Mignon, included in the scope of delivery)
supply the integrated clock with power while the photometer is switched off.
Insert the batteries as follows:
If you set the language, date and time using sections 3.3.4 and
3.3.5, you will soon become acquainted with the easy operation
of the XD 7500. More detailed instructions on operation are given
in Section 4.2 GENERAL OPERATING PRINCIPLES.
1Turn the photometer upside down
and place it on a soft surface.
2Open the lid of the battery com-
partment (1).
3Insert the four batteries in the bat-
tery compartment. Make sure that
the poles of the batteries are in the
correct position.
4Close the lid of the battery com-
partment.

Battery service life The power consumption of the clock is very low. The lifetime of high quality
batteries is at least 5 years.
3.3.2 Connecting the power supply
The power is supplied with the aid of the enclosed plug-in power pack. The
power pack supplies the photometer with low voltage (12 VDC).
CAUTION
The line voltage of the usage location must fulfill the specifications stat-
ed on the power pack (the specifications are also given in Chapter 7
TECHNICAL DATA). Always use the supplied 12 V original power pack on-
ly.
Before plugging in the power cable check whether it is undamaged.
If the power cable is damaged, the instrument must not be operated.
Connect the power
pack
For operation with a
mobile 12 V- power
supply unit
You can also operate the XD 7500 on the move and independent of the local
power supply.
For this, you need a 12 V power supply unit such as, e.g. our 12 V portable
power source (item no. 711050) or our 12 V auto connection cable (item no.
71310020) (see Section 3.4.6).
3.3.3 Switching on the photometer for the first time
During the initial commissioning, the photometer automatically guides you
through the setting of the meter language, date and time after switching on
(see following sections).
1Connect the miniplug of the power
pack to the socket (1) of the pho-
tometer.
2Connect the power pack to a
power outlet.
The display illumination switches
itself on and then off again.
