Using Verified Balances as Legal 

Measuring Instruments in the EU*:

The type-approval certificate for verification applies only to non-automatic

weighing instruments. For automatic

operation with or without auxiliary

measuring devices, you must comply

with the regulations applicable to 

the place of installation. 

● Before using the balance as a legal

measuring instrument, calibrate and

adjust it at the place of use using the

built-in motorized calibration weight;

for details, see “Calibration and 

Adjustment" in the next chapter.

$ The temperature range (°C) indicated 

on the verification label may not be

exceeded during operation.

Example:

Working with CPA2P, CPA26P... 

Models:

Working with the microbalance 

requires a steady hand and a smooth,

uninterrupted technique.

Use forceps or other suitable utensil to

place the sample on the weighing pan.

Perform a number of test measurements

before you begin weighing, to allow the

temperature inside the weighing chamber

to adjust to the ambient temperature

outside the chamber. Otherwise, if the

chamber door was closed for a longer

period of time prior to beginning

weighing, the sudden change in temperature inside the chamber when you

open the door might affect the weight

readout. This is why a series of test

measurements is recommended; the

repeated opening and closing of the

weighing chamber door, at the same

rate of speed as will be used during the

actual weighing sequence, will both

compensate this difference in temperature to some extent and help you 

develop a smooth working rhythm.

Place the sample gently on the weighing

pan. The weight readout should stabilize

within 15 to 20 seconds. The degree of

precision attained increases in proportion as the weighing operations become

more consistent.

Calibration and Adjustment

Purpose

Calibration is the determination of the

difference between the weight readout

and the true weight (mass) of a sample.

Calibration does not entail making any

changes within the balance.

Adjustment is the correction of any 

difference between the measured value

displayed and the true weight (mass) 

of the sample, or the reduction of the 

difference to an allowable level within 

the maximum permissible error limits.

Using Verified Balances as Legal 

Measuring Instruments in the EU*:

Before using your balance as a legal

measuring instrument, you must perform

“internal calibration/adjustment" at the

place of installation after the warmup

period.

Features

Calibration/adjustment can be performed

only when:

– there is no load on the balance,

– the balance is tared, and

– the internal signal is stable.

If these conditions are not met, 

an error message is displayed (Err 02).

Adjustment can be performed

– automatically following calibration 

(1 10 1) or

– manually, at operator discretion, 

after calibration (1 10 2) 

* Including the Signatories of the Agreement on the European Economic Area

– The weight displayed for the sample 

on the balance must not differ from the

nominal weight by more than 2%.

– You can use any of the following

weight units to calibrate/adjust the 

balance: g, kg, lb 

(1 11 1 to 3, factory setting: 1 11 1)

You can block calibration/adjustment 

of the balance as follows:

– Select menu code1 9 7, or

– Close the menu access switch on the

back of the balance

– You can have calibration/adjustment

start automatically when a specified

time or temperature limit is reached

(isoCAL function; 1 15 3).

– You can have calibration and 

adjustment results documented as 

an ISO/GLP-compliant printout; 

see the chapter on ISO/GLP-compliant

Printout/Record.

External Calibration/Adjustment 

in Verified Balances of Accuracy 

Class K

– When the balance is used in legal

metrology, external calibration/adjustment is blocked by a seal over the menu 

access switch.
21

Internal Calibration/Adjustment

The menu code setting 1 9 3

must be selected in the Setup menu.

Inside the balance housing is a 

motorized calibration weight which 

is applied and removed automatically 

for internal calibration.

● Activate calibration: Press (CAL) 

> The built-in calibration weight is

applied automatically. 

> The balance is calibrated.

> If “Calibrate, then auto adjust in one

operation" is selected in the Setup

menu, the balance is now adjusted

automatically.

> The internal calibration weight is

removed.

! Important note for calibration/adjustment of the CPA2P-F model: position

the cover before calibration/adjustment

Calibration and Adjustment Sequence

In the Setup menu, you can configure

whether:

– Calibration is always followed automatically by adjustment (1 10 1; factory

setting), or 

– You have the choice of ending the

sequence or starting adjustment after

calibration (1 10 2) 

If no difference is determined between

nominal and actual weights, you can

end the calibration/adjustment routine

following calibration. 

Two keys are active at this point:

– (CAL) = start calibration/adjustment

– (CF) = end the sequence
22

isoCAL*:

Automatic Calibration and Adjustment

The menu code setting 1 15 3 must be

selected in the Setup menu.

– Temperature range with isoCAL: 

0°C to +40°C

The “AUTOCAL" display automatically

begins flashing if the ambient temperature

has changed in relation to the temperature at the time of the last calibration/

adjustment, or after a defined time interval has elapsed. The balance is telling you

that it wants to self-calibrate and adjust.

This adjustment prompt is activated when:

– The change in temperature or the elapsed

time interval is greater than that shown in

the table below

– The load on the pan has not been

changed within the last 2 minutes

– The balance has not been operated within

the last 2 minutes

– The weight on the pan is no more than 2%

of the maximum capacity of the balance 

*= CPA64-WDS models: 

factory setting isoCAL off (Code 1 15 1)

When these requirements are met, 

the following symbols are displayed:

– C in the measured value line

– AUTOCAL flashes in the symbol display

In the Setup menu, you can configure

the balance to display the adjustment

prompt only, without performing 

calibration/adjustment automatically

(menu code 1 15 2).

! Important note for calibration/adjustment of the CPA2P-F model: position

the cover before calibration/adjustment.

This is necessary to enable automatic

calibration (isoCAL) to take place.

isoCAL Deactivated on Verified 

Balances:

The permitted operating temperature

range for balances used in applications

subject to legal metrology (legal for

trade) is restricted as follows:

– Balances of accuracy class k:

Counting

40

Menu code: 2 1 4

Display symbol: Z

Purpose

With the Counting program you can

determine the number of parts that

each have approximately equal weight.

To do this, a known number of parts

(the reference sample quantity) is

weighed first, and the individual piece

weight (reference weight) is calculated

from this result. Thus the number 

of parts subsequently placed on the 

balance can be determined from 

their weight.

Features

– The minimum load is equal to one digit,

defined according to the resolution of

the active weight unit.

– Press and hold the (F) key (2 seconds) to

set the reference sample quantity.

– Configure the resolution used when

reference sample quantity is stored and

piece counts are calculated.

– Optional automatic output of the piece

count and average piece weight to the

data interface port when the menu 

code 7 1 2 (print application parameters) is set.

– Long-term storage of the last reference

sample quantity “nRef" entered.

– Toggling between piece count and

weight by pressing (F).

Function Keys

(F): 

Begin determination of piece weight

> Application program initialized with

predefined reference sample quantity.

(CF):

End application program; clear 

initialization data

Changing the reference sample 

quantity:

§ Press and hold (F) (2 sec.) 

> Current reference sample quantity 

is displayed.

$ Press (F) briefly to change the value; 

press repeatedly until the desired reference sample quantity is displayed.

Quantities to choose from: 1, 2, 5, 10,

20, 50, 100.

§ Store setting in long-term memory: 

Press and hold (F).

Reference Sample Updating

Automatic reference sample updating

optimizes the counting accuracy. 

You can activate or deactivate this

function in the Setup menu.

When this function is active, automatic

reference sample updating is performed

when the criteria of the factory-set

parameters are met.

> The abbreviation opt, for “optimizing,"

is displayed briefly with the new 

reference sample quantity.

Reference Balance/Scale

(Counting with two balances/scales)

Purpose: 

Use of a reference balance/scale affords

higher precision in counting large

amounts of parts. The CPA balance is

used to determine the reference weight. 

The following weighing instruments or

terminals can be used for sample

weighing in conjunction with a reference balance/scale:

– For a QC scale: set menu code 8 8 2

– For an FB/FC/LA/LP balance/scale: 

set menu code 8 8 3

– For an isi terminal: 

set menu code 8 8 4

§ Please order the required connecting

cables directly from Sartorius.

The following settings must have 

the same configurations in both balances/scales:

– Counting program

– Weight units

– Settings in the CPA balance:

Animal Weighing/Averaging

Menu code: Code 2 1 7 *

Display symbol: V

Purpose

Use this program to determine the

weights of unstable samples (e.g., live

animals) or to determine weights under

unstable ambient conditions. With this

program, the balance calculates the

weight as the average of a defined

number of individual weighing operations (also referred to as “subweighing

operations"). 

Features

– Animal weighing started manually 

or automatically

– Minimum load threshold for starting

animal weighing:

– for automatic start: 

100 display intervals

– for manual start: 

50 display intervals 

– Automatic start:

Begin the averaging operation by

pressing (F). “AUTO” is displayed 

during weighing to indicate that 

the following values will be averaged

automatically.

Animal activity: Averaging begins 

automatically once two subweights are

measured within a predefined tolerance

range (calm = 2%, normal = 5%, 

active = 20%). 

– Number of weighing operations for

calculation of an average mDef can be

set before the beginning of each series. 

* = not available for CPA...-PCE models

– Number of remaining weighing

operations in the current series is shown

during weighing.

– Arithmetic average displayed as a result

in the pre-set weight unit (identified by

G). The V symbol flashes during this

time. 

– Toggling between weighed and 

calculated results by pressing (F) 

(after initialization)

– Unload threshold is one-half of the

minimum load.

– Balance/scale returns to the basic

weighing mode when unloaded; 

i.e., when the load is below the unload

threshold

Synchronization

During data communication between the

balance and a connected device (computer),

messages consisting of ASCII characters are

transmitted via the interface. For error-free

data communication, the parameters for

baud rate, parity, handshake mode and 

character format must be the same for both

units.

You can set these parameters in the 

Setup menu so that they match those of 

the connected device. You can also define

parameters in the balance to make data 

output dependent on various conditions.

The conditions that can be configured are

listed in the descriptions of the application

programs.

If you do not connect a peripheral device 

to the balance interface port, this will not

generate an error message. 

Handshake

The balance interface (Sartorius Balance

Interface = SBI) has transmit and receive

buffers. You can define the handshake

parameter in the Setup menu:

– Hardware handshake (CTS/DTR)

– Software handshake (XON, XOFF)

Hardware Handshake

With a 4-wire interface, 1 more 

character can be transmitted after CTS

(Clear to Send).
61

Software Handshake

The software handshake is controlled via

XON and XOFF. When a device is switched

on, XON must be transmitted to enable 

any connected device to communicate.

Data Output by Print Command

The print command can be transmitted 

by pressing (A) or by a software command

(Esc P).

Automatic Data Output

In the “auto print" operating mode, data 

is output to the interface port without 

a print command. You can have data output automatically at defined print intervals,

with or without the stability parameter.

The length of a print interval depends on

the settings for “Adapting the filter" 

(1 1 x) and “Time-dependent automatic

printing" (6 3 x).

If you select the auto print setting, data

will be transmitted immediately the

moment you turn on the balance. In the

operating menu, you can define whether

automatic printing can be stopped by

pressing (A).

Faster Output Speeds

If you require output speeds faster 

than 10 Hz, please contact Sartorius for

information.

Weighing Instruments for Use in 

Legal Metrology:

Council Directive 2009/23/EC 

“Non-automatic weighing instruments”

This Directive regulates the determination 

of mass in legal metrology.

For the respective Declaration of Type

Conformity for weighing instruments that

have been verified by Sartorius for use as

legal measuring instruments and that have

an EC Type-Approval Certificate, see the

page after next.

This Directive also regulates the

performance of the EC verification by the

manufacturer, provided that an EC TypeApproval Certificate has been issued and

the manufacturer has been accredited 

by an officer of a Notified Body registered 

at the Commission of the European Community for performing such verification.

Sartorius complies with EC Directive 

No. 2009/23/EC for non-automatic weighing instruments, which has been in effect

since January 1, 1993, within the Single

European Market, as well as the accreditation of the Quality Management System 

of Sartorius by Lower Saxony’s Regional

Administrative Department of Legal Metrology (Niedersächsisches Landesverwaltungsamt – Eichwesen) on February 15,

1993.

“New Installation“ Service

Initial verification is covered in our “New

Installation” service package. In addition

to initial verification, this package provides

you with a series of important services

which will guarantee you optimal results in

working with your weighing instrument:

– Installation

– Startup

– Inspection

– Training

– Initial verification

“EC Verification“ – A Service Offered 

by Sartorius

Our service technicians authorized to 

perform the verification* of your weighing

instruments that are acceptable for legal

metrological verification can inspect and

verify the metrological specifications at the

place of installation within the Member

States of the European Union and the 

Signatories of the Agreement on the 

European Economic Area.

Subsequent Verifications 

within the European Countries

The validity of the verification will become

void in accordance with the national regulations of the country in which the weighing instrument is used. For information on

verification and legal regulations currently

applicable in your country, and to obtain 

the names of the persons to contact, please
