2.1 Target group and user qualification
The photometer was developed for use in the laboratory. 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
substances due to their professional training and experience. The operating
personnel must particularly be able to understand and correctly implement
the safety labels and safety instructions on the packages and inserts of the
test sets.

ba75848e01 08/2009
2.2 Authorized use
The authorized use of the photometer consists exclusively of the carrying out
of photometric measurements according to this operating manual. Follow the
technical specifications of the cells in chapter 7 T
ECHNICAL DATA. Any other
use is considered to be unauthorized.
2.3 General safety instructions
The photometer is built and inspected according to the relevant guidelines
and norms for electronic instruments (see chapter 7 T
ECHNICAL DATA). It left
the factory in a safe and secure technical condition.
Note
Opening the photometer or adjustment and repair work must only be
performed by specialist personnel authorized by the manufacturer.
Noncompliance invalidates any claim with regard to the warranty.
Function and
operational safety
The smooth functioning and operational safety of the photometer can only be
guaranteed if the generally applicable safety measures and the specific
safety instructions in this operating manual are followed during operation.
The smooth functioning and operational safety of the photometer can only be
guaranteed under the environmental conditions that are specified in chapter
7 T
ECHNICAL DATA.
If the photometer was transported from a cold environment to a warm
environment, the formation of condensate can lead to the faulty functioning
of the meter. In this event, wait until the temperature of the meter reaches
room temperature before putting the meter back into operation.
Safe operation If safe operation is no longer possible, the photometer must be taken out of
operation and secured against inadvertent operation.
Safe operation is no longer possible if the photometer:
z has been damaged in transport
z has been stored under adverse conditions for a lengthy period of time
z is visibly damaged
z no longer operates as described in this manual.
If you are in any doubt, contact the supplier of your photometer.

2.4 Handling of hazardous substances
When developing test sets, WTW carefully sees that the tests can be carried
out as safely as possible. Some hazards by dangerous substances, however,
cannot always be avoided.
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
instructions 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
handling, occurring hazards, preventive actions and actions to take in
hazardous situations. Follow these instructions in order to work safely.

Pharo 6600 spectrophotometers on the move and independent of the local
power supply.
To do so, a 12 V power supply such as a commercial 12 V portable power
source or a 12 V car battery is required.
Safety instructions For operation with an external battery, follow the safety instructions of the
battery.
Make sure the power source is suitable for operation of the
spectrophotometer (see technical data of the power source and technical
data of the spectrophotometer).
Operating time
with a battery
The maximum operating time depends on various factors:
z Battery (e.g. nominal capacity, condition, age)
z Operating mode of the photometer (e.g. frequency of measurements)
z Photometer (instrument type)
Example:
Operating time with a 12 V / 19 Ah type battery in optimum condition: approx.
16 h

Note
The result of the self-test can be viewed and printed with the [Info] function
key (see section 4.17).
Warm-up time After switching on the photometer requires a warm-up time of 15 minutes.
Reproducibility of measurement data is restricted during the warm-up time.
Therefore, do not measure during the warm-up time.
During the warm-up time, a progress bar appears on the display next to the
date. The progress bar disappears as soon as the warm-up time is over.
The self-test includes:
– the test of the memory,
processor,
internal interfaces,
filter and lamp
– a calibration for each
wavelength
After the self-test is completed,
the main menu is displayed.

AutoCheck With the AutoCheck function the photometer checks and calibrates the
optical measuring unit. The AutoCheck is automatically carried out if
measurement settings were changed since the last measurement, e.g.:
z if a different wavelength was selected or
z if a different method was selected.
If necessary, the photometer asks you to remove the cell from the cell shaft.
With unchanged measurement settings, the AutoCheck is carried out in the
background at regular intervals of 5 minutes. The AutoCheck can only be
carried out in the background if the cell shaft is empty. If a cell is in the cell
shaft the AutoCheck is carried out only after the cell was removed.
Note
Remove the cell from the cell shaft after every measurement. Thus the
photometer can carry out the regular AutoCheck.
Cells must be completely removed from the cell shaft.
Cells that are removed only half disturb the AutoCheck measurement and, as
a consequence, falsify measured values until the next AutoCheck is carried
out.
Plastic cells that are not recognized by the automatic cell recognition also dis-
turb the AutoCheck.
Note
During a running kinetic measurement the photometer cannot carry out any
AutoCheck. That is why in this case a warm-up time of two hours is required.
After this time the signal is stable enough so that the measurement accuracy
is secured over a longer period of time.
Display illumination The photometer automatically switches off the display illumination if no key
has been pressed for 5 minutes. The illumination is switched on again with
the next keystroke. The function of the key becomes active only with the
following keystroke.
Switching off To switch the photometer off, keep the <ON/OFF> key depressed until the
photometer is switched off.
