1. GENERAL INFORMATION
1.1 INTENDED USE
The balances are designed to provide accurate measurement of weighed loads, performed under
laboratory conditions.
1.2 PRECAUTIONS
• Prior to first use, it is highly recommended to carefully read this User Manual, and operate
the balance as intended.
• Do not use the balance for a dynamic weighing. Even if small quantities of weighed material
are added or removed from the weighing pan of the instrument, the reading should be taken
only after stabilization of the measurement results.
• Do not place any magnetic materials on the weighing pan, as this can cause damage to the
measuring system of the instrument.
• While loading the balance make sure that load is placed in the very center of the weighing
pan.
• Make sure the load does not exceed instrument’s measuring range (maximum capacity).
• Do not leave heavy loads on the weighing pan for a long period of time.
• In case of failure, immediately unplug the instrument.
• Balances to be decommissioned, should be decommissioned in accordance with valid legal
regulations.
• Do not use the balance is areas endangered with explosion. The balance is not designed to
operate in EX zones.
1.3 SUPERVISION OVER METROLOGICAL PARAMETERS
Metrological parameters of a balance need to be checked by an authorized user. Inspection
frequency is qualified by the ambient conditions in which a balance is used, processes carried out
and adopted quality management system.
1.4 WARRANTY CONDITIONS
A. Cole Parmer will exchange, replace or repair the existing balance for any damage that
appears to be faulty by production or by construction within the 5-year warranty period.
B. Warranty is voided if:
• mechanical defects caused by inappropriate use:
• defects of thermal and chemical origin,
• defects caused by lightning, overvoltage in the power network
• defects caused by water damage
• or other random event
• overloading the mechanical measuring system
• installing another version of the operating system
• utilizing the balance contrary to its intended use
• repairs carried out by non-authorized service centers
• removing or destroying protective stickers which secure the balance’s housing against
unauthorized access
C. Warranty card must be filled out for warranty to be valid.
6
2. UNPACKING AND INSTALLATION
2.1 PLACE OF USE AND ASSEMBLING
• The balance should be stored and used in locations free of vibrations and shakes, free of air
movement and dust.
• Ambient air temperature should not exceed the range of: +10 °C ÷ +40 °C.
• Ambient relative humidity should not exceed 80%.
• During balance operation, ambient temperature in the weighing room should not change
rapidly.
• The balance should be located on a stable wall console desk or a stable working table which
is not affected by vibrations and distant from heat sources.
• Take special precaution when weighing magnetic objects, as part of the balance is a strong
magnet. Should such loads be weighed, use under-pan weighing option, which removes the
weighed load from area influenced by the balance’s magnet. The hook for under-pan
weighing is installed in balance’s base.
• Keep all package element should your device be transported in the future. Remember that
only original packaging can be used for shipping purposes. Prior to packing, uncouple any
cables, remove any separable components (weighing pan, shields, inserts). Pack the device
components into an original packaging. The original packaging protects the equipment
against potential damage during transportation.

2.5 BALANCE LEVELING
It is necessary to level the balance prior to plugging it in. To level the balance, turn its feet until the
air bubble is in the center position.
The balance should firmly rest on a surface, each of the feet must be supported.
2.6 POWERING THE DEVICE
Before plugging in your balance, it is imperative to wait until the balance reaches thermal
stabilization.
For balances that were stored in much lower temperatures (e.g. during winter period), thermal
stabilization period will take at least 4 hours for Precision balances, and 8 hours for Analytical
balances.
• Balance should be plugged in only with the power adapter that comes standard with the
model. Nominal power supply of the power adapter (specified on the power adapter data
plate) should be compatible to the power supply.
• Plug the balance in – connect the power adapter to the socket, next connect its connector to
port located at the back of the balance housing.
• Press button located in the top right hand corner of the key pad.
! Remember to start the balance with no load on the weighing pan
• Test of the display unit takes place right after connecting the balance to the power, all the
elements and pictograms are backlit for a short time.
• Next, the name and the program number appears (please note, program number may be
different than what appears below)

• If the indication is different than zero, please press button
2.7 AMBIENT CONDITIONS STATE INDICATION (ANAL YTICAL BALAN CES )
The function is intended to inform on unstable ambient conditions for a balance, it is enabled only
for Analytical balances.
The function controls dynamic temperature changes occurring in the balance during its operation. If
the variation is greater than set limit values (temperature changes speed), then a blinking
thermometer pictogram is displayed on the screen.
The blinking thermometer pictogram means that temperature inside the balance is not stable, this
may result in inaccurate mass measurement. For such a case it is recommended to wait until the
temperature stabilizes or to perform balance adjustment (blanking of the blinking thermometer
pictogram).

change of the unit is possible.
19
Procedure:
4.5 USER-DEFINED UNIT Balance Menu: P8.3 USER UNIT U1
P8.4 USER UNIT U2
You may create two custom user-defined units. Displayed value of a user-defined unit is a
multiplication of measured mass value and a coefficient specified for the user-defined unit. The units
can be freely named with use of 3 characters’ maximum.
By default, the names are displayed as <u1> – user unit 1 and <u2> – user unit 2.
Procedure-
4.6 BALANCE ZEROING
Zeroing is a function allowing to zero the mass on the indication. To perform this function, press
button. Mass indication of zero value shall be displayed together with precise zero and
stability markers .
The zeroing process is an equivalent for determining new zero point, recognized by the balance as
precise zero. Zeroing is possible only for stable status of display indication.
20
! CAUTION
Zeroing the display indication is possible only within ±2% range of instrument’s maximum
capacity. If the zeroed value is above ±2% of the maximum capacity, then the balance
indicates a respective error message.
4.7 BALANCE TARING
Taring is a function allowing to determine net weight of a measured object. To determine the net
weight of the object, place object’s container (packaging) on the weighing pan, and on stabilization
of measurement result press key. The display indicates mass equaling zero and symbols:
Net and . On taking off the weighed load and its packaging from the weighing pan, the display
indicates sum of total tared mass with a minus sign.
The balance allows the user tare value to a database-stored product. Using this option, the software
automatically uploads data on tare value for a particular product upon its selection from the
database.
! CAUTION
Taring negative values is impossible. On taring negative values the balance responds with
an error message, Err3. In such case, zero balance indication and repeat taring procedure.
4.7.1 MANUAL TARE DETE RMINATION
This option allows for the setting of a tare value through a manual input of the value.
Procedure-
• Press quick access key F2, to which <ENTER TARE> option has been assigned.
• Wait for a respective window to open.
• Use the arrow buttons to enter the tare value and press button,
• The balance returns to the weighing mode, and the display indicates entered tare value
with minus “–" sign.
4.7.2 DELETING TARE
Entered tare value can be deleted by pressing button or by entering tare value of 0.000g
(see description above).
4.7.3 TARE DATABASE

4.7.4 AUTOTARE
Autotare is used for quick determination of net weight for loads with different tare values,
wherein they are measured one after another.
When the function is act i ve (<AUTOTARE> parameter set to <YES> opt ion), the operating
process takes the following steps.
Procedure-
• Make sure that the weighing pan is empty and press button responsible for zeroing.
• Put product packaging on a weighing pan.
• After measurement stabilization, automatic taring of the packaging mass takes place
(Net marker then appears in the upper part of the display).
• Place product to be weighed into the packaging.
• The display shows net weight of the product.
• Remove the product together with the packaging from the weigh pan.
• The balance removes the tare value (packaging weight recorded during the first step of
the operating process) after the gross weight value (set in <AUTO THRES> parameter)
has been exceeded.
• Place packaging of the next product on the weighing pan, automatic taring of the
packaging weight proceeds after measurement stabilization (Net m arker appears in the
top section of the display);
• Place next product that is to be packed.
For correct operation of the balance with AUTOTARE function, it is necessary to adjust the
threshold value.
<AUTO THRES> parameter is connected with the following functions:
• automatic tare
• automatic operation
No automatic taring takes place as long as the gross weight value stays within the range set in
<AUTO THRES> parameter.

4.8 WEIGH MODE SETTINGS
The software allows setup of operating parameters (filters, value release and autozero function,
deleting the last digit and other settings) separately for each working mode. Only for User profile
you can modify all settings. For other profiles (Fast, Fast dosing, Precision) Filter and Value
release parameters are default and cannot be modified.
It enables customizing the instrument and utilizing its properties depending on your needs and
expectations, or on specific requirements for selected working mode (e.g. DOSING); as a result the
device operation is quick and easy.
To simplify weighing instrument operation, there are 4 profiles in the software. The profiles are
selected and saved so that the weighings for respective requirements and conditions are optimized.
Profile settings apply to settings for specific working mode and are grouped in the following
parameter: Setup/Working modes/Weighing/Readout. For detailed description of these settings go
to the next section of this user manual.
These are the following profiles:
• User – the basic profile for which filter settings are selected in a way enabling fast and
precise weighing.
• Fast – profile enabling weighing of any mass regardless of the working mode. When running
the balance for the first time, this profile is started automatically. For this profile the
parameters are selected in a way enabling obtaining the measurement result as fast as it is
possible,
• Fast dosing – the profile is dedicated for fast dosing.
• Precision – the profile is dedicated for precise dosing of any mass regardless of the
working mode. For this profile the weighing process takes the most time, but the result is the
most accurate and precise,
Caution: You can modify all settings of User profile. Settings of other profiles (Fast, Fast dosing and
Precision) can be modified only to a limited extend.
Name of currently selected profile is displayed in the bottom line. The profile can be selected
individually for working mode. The balance saves the last used profile in each working mode (with
your modifications) and starts operation with that profile selected.
Procedure:
• Select <PROFILE> option upon pressing key.
• Using navigating keys, select profile and press key.
• The balance returns to weighing mode and operates in accordance with set profile.

The higher filter level, the longer the weighing time.
4.8.1 FILTER LEVEL SETTING
Filter level setting (function unavailable for the following profiles: Fast, Fast dosing,

Fi
lter settings adjustment depends on the working environment. For the best possible conditions
the filter can work in a very fast mode (V.FAST value for Filter parameter); however, if the
conditions are poor (shakes, drafts), the filter should be set to slow or very slow option (SLOW
or V. SLOW value for Filter parameter). The effectiveness of the filter is different throughout the
weighing range. The filter works slower when “approaching” the weighed mass, it works more
intensively for weighed mass within the set range of the filter (the parameter for setting filter
range is accessible only from the service menu – the user does not have any access to it).
D
epending on the filter, the weighing time is shorter (V.FAST and FAST) or longer (SLOW and
V. SLOW).

Procedure-
4.8.3 AUTOZERO FUNCTION
alance Menu: P2.2.1.3 AUTOZERO
B
T
he balance features an autozero function (Auto). This function automatically controls and
corrects the zero reading. When Autozero is enabled, it compares balance readings at declared
time interval e.g. 1s, if weighing pan is unloaded and display indication is close to zero. If results
vary less than declared AUTOZERO range e.g. one division, balance zeroes automatically,
marker of stable measurement result , and precise zero marker are displayed.
If AUTOZERO function is enabled, then each weighing process starts from precise zero point.
There are, however, some instances when this function can be a disturbing factor for the
measuring process; e.g. very slow placing of a load on the weighing pan (load adding). Here,
zero reading correction can also correct the actual reading of loaded mass.

he automatic calibration process can take place in the following instances:
alance Menu: P1.6 AUT. CALIB.
B
• <NONE> automatic calibration disabled
• <TIME> calibration takes place in time intervals. The time interval is declared in hours
and ranges between 0.5 and 12 hours.
• <TEMP> calibration is triggered by temperature change only. At each calibration
ocess, the temperature is recorded. The next calibration is automatically initiated if
pr
temperature changes more than 1°C or 2°C from the last saved temperature.
• <BOTH> calibration is triggered by both, temperature changes and time.
27
Procedure:
• The balance detects the necessity of carrying out a calibration and signals it by
displaying a thermometer or clock pictogram and <Cal> sign at the top of the display
• Once the balance signals the need for a calibration, a 2-minute long time interval takes
place allowing the weighing procedure to be completed
• Once the 2-minute long time elapses, the balance display shows the message CAL_30
tarts counting down from 30..29..28 to 0 (indicated value is the counter)

• The balance user has 30 seconds to make a decision
• To allow the internal calibration, do not take any actions
• If more time is needed to complete weighing procedure, press Esc.
When pressed, the balance returns to weighing procedure and displays last
weighing result.
In about 5 minutes balance indicates CAL_30 message again.
• The calibration process can be postponed multiple times, however, postponing the
alibration for a long time can lead to larger errors in the weighing process. The errors
