1.2 Inserting the rechargeable
batteries/lithium powerpack
Before operating the system for the first time, the rechargeable
batteries and the lithium powerpack included in the package
must be installed.
The batteries enclosed in the package are not charged.
ABattery pack: 7 nickel-cadmium batteries (type AA, 750 mAh)
BBattery: lithium battery (type CR 2032, 3V)
CFuse: 1 A, delayed-action, 20 mm
1. Ensure that the Spectroquant® Multy Colorimeter is switched off.
2. Remove, where applicable, the cell from the measurement
compartment.
3. Place the unit on its front on a clean, flat surface.
4. Remove the two screws (E) on the battery-compartment cover
(F) on the bottom of the unit.
5. Remove the batteries cover (F).
6. Remove any old batteries (A) and/or the lithium powerpack (B).
7. Insert 7 new rechargeable batteries and/or the lithium
powerpack
.
Make sure that the batteries are inserted correctly!
8. Attach the battery-compartment cover.

1.2.1 Lithium powerpack –
Important information
The lithium powerpack (B) serves to save all important data
(saved measurement results, settings) for approx. ½ year when
the unit is not being supplied with power by the battery pack
or the mains supply.
As long as the colorimeter is being supplied with mains or
battery power, it does not draw any power from the lithium
powerpack. Since lithium powerpacks have a very long life,
it will in all probability not be necessary to exchange the
one supplied. All the same, to ensure proper functioning it is
recommended to replace the lithium powerpack every five years.
Note
When neither the mains adapter nor the battery pack are
supplying power, removal of the lithium powerpack will result
in a complete loss of data (saved measurement results and
settings). For this reason we strongly recommend that the unit
is connected to the mains power supply while replacing the
lithium powerpack.
1.2.2 Charging the battery pack
The rechargeable batteries (A) remain in place in the photo-
meter for recharging. Once the mains power supply is established,
the batteries start to be charged.
Charge the rechargeable batteries in the instrument for 5 days
(working with power from mains is possible). Now use the
instrument without mains until the first battery warning comes
up. Charge again, 4 days this time. Repeat usage to battery
warning and charging four times.
Approximately 10 charging/discharging cycles are required until
the batteries reach their full capacity.
The unit can be operated with mains power supply with or
without the batteries in place. For this you must attach the
country-specific wall-socket adapter to the mains adapter.
en

10
1.2.3 Using non-rechargeable batteries
In principle it is also possible to operate the unit using conven-
tional batteries – in this case, however, they must never be
used in combination with the mains adapter. The charging
process would start automatically as soon as the colorimeter is
connected to the mains power supply. Conventional batteries
are destroyed by the charging current, resulting in severe dam-
age to the unit. This also involves the risk of fire and explosion.
1.2.4 Using the protective caps
To protect the connection terminals on the unit from damage
(e.g. corrosion) due to environmental influences such as e.g.
dust or water splashes, the supplied protective caps should be
attached over the connection points (D) when these are not
being used.

The display then shows:
Pressing the [Enter] key takes the colorimeter to method
selection.
Any data already saved in the unit must be deleted (mode 34,
see chapter 1.7, "Delete data"), the user-method system must
be initialized (mode 69, see section 5.6.5, "Initializing the
user-method system (concentration and polynomials)"), and
the date and time should be reset. (See below for details.)
The Spectroquant® Multy is supplied with English preset as the
standard language setting. Before making the first measurement
you should therefore reset the unit to the language of your
choice. To do this go from the method list and change to the
mode menu by pressing the [Mode] key.

after the last time a key was pressed. In the last 30 seconds before
it switches off, the unit emits an acoustic signal. During
these 30 seconds you can press a key to prevent the unit from
switching off automatically. The automatic switch-off function is
inactive while the unit is performing operations (running countdown,

Note
The five-digit item number (e.g. 14541) gives the five digits
in the middle of the catalogue/ordering number 1.XXXXX.0001,
in this case 1.14541.0001. In some cases in which the assign-
ment is self-evident (e.g. monochloramine)
or else in which all Spectroquant® tests available for one
parameter can be used (e.g. chlorine), this number is not shown.
For an overview of all programmed methods please refer to the
included CD, section 5.1, “Overview of preprogrammed methods
and analytical procedures”.
2.2 Measuring with test kits
A detailed description of the procedure for the selected method
is given on the provided CD in section 5.1, “Overview of prepro-
grammed methods and analytical procedures”. The procedures
may differ slightly from those described in the respective pack-
age inserts.
After selecting the method, prepare the blank and sample for
measurement.
In the case of analysis specifications in which reaction times
must be observed, a timer (countdown) is integrated in
the method programme. (In such cases the cells must not be
inserted into the measurement compartment.)
After the method has been selected the display shows:
Example: Method 90, Bromine 00605
If you wish to exit the menu at this stage, simply press the
[Enter] key twice (= abort countdown) and then the [Esc]
key once.
After the method has been selected, the countdown function
is started by pressing the [Enter] key. The remaining time is
shown continuously. An acoustic signal is emitted in the last
10 seconds before the countdown expires. After the countdown
has run out, proceed as described in the analysis procedures.
In some methods there are several reaction times that have
to be considered; these are shown and processed in the proper
sequence.

Note
The running countdown can be skipped by pressing the [Enter]
key once. In this case the user must observe the necessary
reaction time him-/herself. (Failure to observe the specified
reaction time can lead to erroneous results.) Further options
to deactivate the countdown procedure: mode No. 13 or
Profi mode (mode No. 50).
After the countdown has expired the display shows:
Place the prepared blank in the measurement compartment
with the mark on the cell pointing towards the mark on
the unit case.

or, respectively,
the concentration of the sample lies above the measuring range.
After the result has been displayed
• it can be saved (see section 2.7, “Saving measurement results”
and section 2.8, “Retrieving saved measurement results” for
further details)
• it can be printed out (see section 5.3)
• a new method can be selected:
pressing the [Esc] key takes the colorimeter back to the
method-selection mode;
you can also enter a new method number directly
(confirm by pressing [Enter])
• further measurements can be made using the same or a
new zero setting:
• If you wish to measure other samples using the same method:

2.4 Altering the citation form
Wherever this is appropriate, it is possible to alter the citation
form (see section 5.1, “Overview of preprogrammed methods
and analytical procedures” for possible citation-form alterna-
tives).
After the first sample has been measured using a specific
method and the result is shown on the display, you can alter
the citation form in the following manner:
