Calibration/Adjustment

PurposeCalibration technically means to determine the difference between the weighing instrument readout and the actual weight on the platform to determine the accuracy.Calibration does not entail any modification of the calibration weight value stored in themass comparator.Adjustment is the correction of the difference between the measured value displayed andthe true weight (mass) of a sample, or the reduction of the difference to an allowable levelwithin maximum permissible error limits.During calibration, the mass comparator is adjusted to changes in the ambient conditions.Calibrate/adjust your mass comparator at the place of installation:

– after each warmup period– before the first weighing operation– following a change in ambient conditions– each time the mass comparator is set up in a different area

Use only calibration weights of an accuracy equal to or better than the particular accuracyclass of your mass comparator. See the section entitled “Accessories” for an overview ofthe calibration weight sets available. You will need calibration weights of the followingaccuracy classes:

Model CC30002 CC50002Weight (g) 1x10000 1x20000Accuracy class E2 E2

– Tare the mass comparator when the display has stabilized.

– Press and hold the t key (11) approx. 2 seconds

> The Application display shows “C.E.” (“calibration: external”), and the function displayshows “CAL”.

– Press f (7) to initiate the calibration routine; the calibration weight (10000 or 20000 g)is displayed.

– Center the calibration weight on the weighing pan.

> The mass comparator is calibrated automatically. At the end of calibration, the calibra-tion weight value is displayed with the weight unit and an acoustic signal is emitted.

Note:You can also enter the conventional weight of your calibration weight via the numerickeys to adjust the sensitivity of the mass comparator more precisely. To do this, press f(7) (CAL) to display the currently valid calibration weight. Now you can enter the desiredweight value using the numeric keys. Press f (7) again (STO) to store the weight value;the previous value is overwritten. Center the prompted weight on the weighing pan. The value you entered is stored automatically. If the error code “Err 02” is displayed, this indicates an error or disturbance in starting the calibration procedure.

– In this case, press t briefly and then, when the display shows a zero readout, press thef key again.

Note:Press and hold the f (7) key to store the values in non-volatile memory.

Blocking the Calibration/Adjustment FunctionsYou can block these functions by setting code 1 9 2.

Working with the Mass ComparatorWorking with the mass comparator requires a steady hand and a smooth, uninterruptedtechnique.

– Perform a few trial weighing procedures before you begin the actual mass comparisonsequence, to get a feel for the handling method required.

> The weights and the mass comparator should remain next to one another in the weighingroom for an extended period to condition them to the same temperature.

– Place the weight gently on the weighing pan.Moisture or warmth from your hands can cause measuring errors.For best results, wear gloves or use weight handles or forceps while working with themass comparator (see “Accessories”).

– Always place the weight in the middle of the pan. If the weight is not centered, this mayresult in systematic deviations in the weighing results which can influence the accuracy ofyour measurement unnecessarily, resulting in longer response times.

General Directions– Press the e key (16) to turn on the mass comparator

– Center your reference weight on the weighing pan

– Calibrate/adjust the mass comparator if necessary

> After a brief period, a readout appears on the display. Press the t key (11) to set it to 0.00 g.If the displayed value changes after you have set it to zero, tare the mass comparatoragain. If the display continues to change, make sure you are observing the instructionsgiven in the section entitled “Working with the Mass Comparator.”

– Remove the reference weight from the weighing pan.

– Place your test weight on the weighing pan.

> After a brief period, the display shows the difference between the reference weight andthe test weight with the respective plus or minus sign.

– Read off the weighing result after the mass comparator has stabilized.

Note:Weighing with a mass comparator is a method of measuring by comparison, known as comparative weighing. The known mass of a reference weight is compared to the massof the test weight, in a two-part weighing procedure. The difference in mass is shown inthe weight display (13) along with the respective plus or minus sign.With full range mass comparators you can perform comparison weighing in any range, up to the maximum capacity.

Weighing MethodsFor accurate results, we recommend using the “A-B-B-A” or “A-B-A” method, wherebythe difference in mass between test weight (B) and reference weight (A) is determinedrepeatedly and the average of the individual weighing results is calculated from the meanvalue of the measured differences.

A-B-B-A MethodPlace the reference weight (A) and the test weight (B) alternately on the weighing pan in the sequence shown below, maintaining a smooth, steady pace:

A– –B– –B– –A– –A– –B– –B– –A– –A– –B– –B– –A– etc.

1st cycle 2nd cycle 3rd cycle etc.

A-B-A MethodPlace the reference weight (A) and the test weight (B) alternately on the weighing pan in the sequence shown below, maintaining a smooth, steady pace:A– –B– –A– – –B– –A– –B– –A– –B– –A– etc.

1st cycle 2nd cycle 3rd cycle etc.

Please note when using either of these methods:The time intervals between A-B and B-A or between B-B and A-A should always be the same.This produces a smooth, steady working rhythm.

Note:Always lift the weight completely off of the weighing pan.

15

Connecting Electronic Peripheral DevicesBefore you connect a peripheral device (such as a printer or PC) to the interface port:

§ Make absolutely sure to unplug the mass comparator from AC power - also before disconnecting a peripheral device from the mass comparator data interface (20).

> To document measurements with a Sartorius printer, connect the printer to the interfaceport (20).You do not need to adjust any settings.

§ Re-connect AC power.

§ To print or output data, press the p key (9).

In the operating menu, you can define how your mass comparator adapts to ambientconditions and also how it works to meet your special requirements.

The factory-set menu codes are identified by an asterisk (“*”) in this manual. You can select a function not marked with “*” by selecting the corresponding menu code.These codes are listed in the section entitled “Mass Comparator Operating Parameters”. If you need to change any of the factory settings, we recommend that you note the newsetting here, along with the date the change was made.

Changing Menu Code SettingsTo select specific functions, you will need to set the respective menu codes. There are three steps to changing a code:

– Accessing the menu

– Setting the code

– Confirming and storing the code

The keys have special functions when setting menu codes. The four keys used to set thecodes appear as arrows in the illustration on the left:

< w and > p = Move to the right and left

f and v F = Increase/decrease a digit value by one

t= Confirm a code setting

c = Store code setting and exit the menu

Example:Now try changing a code yourself. Follow the example below to change the power-onmode to “Automatic power-on”.

The menu code for “Automatic power-on” is 8 5 4.

Configuring the Data Record

Sartorius mass comparators come with an interface as standard equipment.You can plug a Sartorius printer or a computer into this interface port. In addition, you canchoose to have data transmitted to or from your mass comparator to the connected deviceeither automatically or by pressing a key.The mass comparator operating menu lets you define the various parameters for data output.For information on the data formats and for interfacing a computer or a different peripheraldevice, please refer to the chapter entitled “Data Interface”.

Data Output Parameter

This parameter is coupled with the stability parameter; stability = stable readout or nomotion is detected.Print on request = data is output when the output key is pressed or a software command isreceivedAuto print = continuous, automatic data output


Print on request regardless of stability 6 1 1

Print on request after stability, with storage of the function 6 1 2 *

Print on request at stability without storage of the function 6 1 3

Auto print regardless of stability 6 1 4

Auto print at stability 6 1 5

Automatic Data OutputYou can stop and start automatic data output (auto print function) by pressing the p key(9). To avoid operating errors or to ensure that the data is output continuously in the auto-matic mode, you can block this function.


Start/stop auto print using the p key (9) 6 2 1

Auto print not stoppable 6 2 2 *

Data Output at Defined Intervals

You can reduce the volume of data in the “auto print” mode by defining the interval atwhich data will be output automatically. This auto print interval is based on the number of display updates.

Auto print interval Menu code Factory setting Changed

1 display update 6 3 1 *

2 display updates 6 3 2






Automatic Tare Function

You can choose to have the mass comparator zero/tare automatically after the output key ispressed.


No automatic taring 6 4 1 *

Automatic taring after the p key (9) is pressed 6 4 2

Data ID Codes

The ID code for weighed values consist of a code letter printed or displayed in front of thesevalues.If you select “without data code,” only the weighed value is output. This setting must be changed to generate ISO/GLP-compliant data records. The ID code increases the data output format for each weight readout from 16 to 22 characters.

Power-On Mode

Depending on your requirements, you can change the power-on mode of your mass com-parator.

The factory setting is: (power) –> off <–- > on <–> standby <.

If you select “Toggle between on and standby,” the mass comparator automatically switcheson again after it has been temporarily disconnected from AC power or a power failure hasoccurred (menu code 8 5 3).

In the “Automatic power-on” mode, the mass comparator will automatically turn on againafter it has been temporarily disconnected from AC power, after a power failure has occurred,or when you press e (16). With this setting, pressing the e key does not switch the masscomparator off.

ISO/GLP-compliant Printout or Record

Application:

Use of the mass comparator as a test and measuring instrument in quality assurance systemsin compliance with the requirements of ISO, GLP, GMP and EN (European Standards) inwhich proof of the mass comparator’s accurate performance is required.

The mass comparator can record all completed calibration or adjustment operations andprint out data in compliance with the requirements of Good Laboratory Practice (GLP). The mass comparator, interfaced with a data printer or a computer, generates documentationthat includes the date, time, serial number and model designation, which means data can beunambiguously traced to the mass comparator that generated it and the time at which it was generated.

Select the ISO/GLP-compliant printout or record mode by setting the corresponding code inthe operating menu.
