be used alone or in combination with
an application program (counting,
weighing in percent, etc.).
Features
– Taring the balance.
– Assigning IDs to weights (as needed).
– Printing weights.
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.
G 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/Adjustment"
in this chapter.
$ The temperature range (°C) indicated
on the verification label may not be
exceeded during operation.

ment on the European Economic Area
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 homogenous.

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" 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 Agree-
ment 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 page 51.
External Calibration in Verified
Balances of Accuracy Class K
– When the balance is used in legal
metrology, external calibration is
blocked by a seal over the menu
access switch.
WWW.BALANCES.COM
22
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.
G 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/adjust-
ment 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 auto-
matically 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 routine following
calibration.
Two keys are active at this point:
– (CAL) = start adjustment
– (CF) = end the sequence
WWW.BALANCES.COM
23
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/adjust-
ment 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
