First Steps 21

6   Applications for Pipette Calibration

6.1   Operating philosopy and settings

Before you start work with your XP26PC, you should therefore familiarize yourself with the operating philosophy and settings of this balance. You will find this information in the Operating Instructions – Part 2 and Part 3.

6.2   Suitable applications for pipette calibration

The XP26PC offers all the applications of the XP balances. However, of those applications, only the following applications are suitable for calibrating pipettes:

Weighing

Statistics

Percent weighing (in exceptional cases)

You will find information about these applications in the Operating Instructions – Part 2. Please read the respective chapter and familiarize yourself with the settings and how to work with the applications.

6.3   Selecting the application

1 Press « ».

2 To select the symbol for the desired application.

Note

For greater clarity, you can switch off the applications you don’t need.

See Operating Instructions – Part 2.

6.4   Setting for the light barrier

The light barrier of your XP26PC automatically opens and closes the automated trap door of the draft shield when you pass the pipette through the light barrier. This saves you having to close the trap door manually with the « » key. From the point of view of the XP26PC, the light barrier is an "ErgoSens" and must therfore be con­ figured as follows:

22 First Steps

1 Press « ».

Window Setup opens.

2 Localize the settings for Smart & ErgoSens.

At the factory settings, both SmartSens sensors are configured for door opening.

3 Switch both SmartSens off (or assign to them any function except door opening).

At the factory, both ErgoSens are switched off.

4 On the ErgoSens to which the light barrier is connected ("Aux 1" or

"Aux 2"), activate the function for opening the door.

Example

ErgoSens 1 (Aux1) > «Door»

The light barrier is now active.

Note

If you are working with the METTLER TOLEDO Calibry PC software, a different setting must be used.

See Settings for the automated trap door function (page 24).

6.5   XP26PC and Calibry

METTLER TOLEDO Calibry is a PC software for calibrating single- and multi-channel pipettes. When Calibry is started, it recognizes your XP26PC balance and automatically makes the required settings.

Except

Setting for the door function described in Settings for the automated trap door function (page 24).

Calibry controls and records all calibration operations, calculates statistical values, and generates calibration records. Calibry contains a database with a large number of pipette types available on the market and allows the definition of various methods of calibration for them. Calibry also monitors the dates for subsequent calibra­ tions.

Please request Calibry documentation from METTLER TOLEDO.

6.5.1   Connection to the host computer

The XP26PC is connected via the built-in RS232C interface to the host computer. If the host computer has an

RS232C interface, an RS interface cable (RS9 – RS9 cable) can be used. Alternatively, the XP26PC can also be connected via a USB-RS232 adapter cable (USB serial converter) to a USB interface of the host computer. Both cables are available as options. If several balances are connected to one host computer, each balance is con­ nected with a USB-RS232 adapter cable to a USB hub. The various different ways of connecting with USB are explained.

See Accessories (page 34).

System comprising one single XP26PC balance

1 Connect the 9-pin plug of the USB–RS232 adapter cable to the RS232C socket on the back of the XP26PC.

2 Connect the USB plug of the adapter cable to a free USB interface on your PC.

6.5.2   PC software

The Calibry software that is optionally available from METTLER TOLEDO can be used on your PC. Alternatively, the XP26PC balance can also be integrated into an in-house application that already exists or that will be spe­ cially created.

See Accessories (page 34).

The main functions of the PC software are as follows:

Configuration of the XP26PC balances that are connected.

Differentiating between data and control commands.

Assigning COM ports to individual measurement operations and canceling the assignment when the mea­ surement is complete.

Monitoring the number of completed and still ongoing pipettings.

Saving and analyzing measurement data.

6.5.3   Communication settings

1 For fault-free communication with the PC software, the RS232C interface of the XP26PC must be set to

Host.

2 The interface parameters of the balance and PC must be identical (baud rate, bits/parity, etc.).

See Operating Instructions – Part 2.

Note

The factory settings for the interface parameters of the XP26PC balance and the Calibry software are identi­ cal.

If the XP26PC and Calibry are operated with the factory settings for the interface, there is no need to make any settings.

6.5.4   Settings for the automated trap door function

Calibry controls the automated trap door of the XP26PC balance depending on the measurement values that it receives. For it to function, a special setting must be made both on the balance and in Calibry.

For more details refer to the Calibry Operating Instructions.

24 Applications for Pipette Calibration

7   Calibrating Pipettes

It is assumed that the balance is switched on and that you have already made the settings according to

chapter Selecting the application (page 22) and Setting for the light barrier (page 22).

– After you have switched on the balance, wait at least 2 hours before you start work.

This allows the balance to adapt to the ambient conditions.

7.1   Fill water container

The draft shield with glass cover and the water container serve as an evaporation trap. Inside the evaporation trap, there is a virtually saturated atmosphere that prevents evaporation of water from the pipetting container and consequent distortion of the measurement results.

1 Remove the automated trap door and the glass cover.

2 Check the level of liquid in the water container.

The container should be at least half full.

3 If the water level is too low, add distilled water.

Attention

Do not overfill the container!

4 Replace the glass cover and mount the automated trap door.

Important

Wait at least 2 hours before the next calibration, so that the tempera­ ture and humidity in the measuring chamber are correct.

7.2   Perform the calibration

1 Press the «G» key to set the balance to zero.

For pipettes with variable volume:

2 On the pipette, set the volume for the first measurement operation

(e.g. 10% of the nominal volume).

Comply with any additional instructions for preparing the pipette

(e.g. according to ISO 8655).

3 With the pipette, suck the set volume out of the water bath.

4 Pass the tip of the pipette through the light barrier to open the auto­ mated trap door.

5 Empty the pipette into the pipetting container.

Comply with all rules for correct pipetting (e.g. ISO 8655).

6 Pass the pipette back through the light barrier to close the automat­ ed trap door.

When the measurement result becomes stable (the circle of the stability detector left of the results disappears) you can read the result.

If a PC is connected, you can transmit the result to the host computer by pressing the « » key or the [Transfer Key] func­ tion key.

See Operating Instructions – Part 2.

If you are working with the METTLER TOLEDO Calibry software, the result is automatically transmitted to the host computer.

See XP26PC and Calibry (page 23).

7 Before you perform the next pipetting, press the «G» key again to reset the display to zero.

Calibrating Pipettes 25

8   Maintenance

8.1   Cleaning

Periodically clean the weighing chamber, the housing, and the terminal of your balance using the brush sup­ plied with it. The maintenance interval depends on your standard operating procedure (SOP).

Please observe the following notes

Risk of electric shock

a) Disconnect the balance from the power supply prior to cleaning and maintenance.

b) Only use METTLER TOLEDO power cable, if these need to be replaced.

c) Ensure that no liquid comes into contact with the balance, terminal or AC adapter.

d) Do not open the balance, terminal or AC adapter.

These contain no user-serviceable parts.

Damage of balance

On no account use cleaning agents which contain solvents or abrasive ingredients, as this can result in damage to the terminal overlay.

Cleaning

Your balance is made from high quality, resistant materials and can therefore be cleaned with a commercially available, mild cleaning agent.

Note

Please contact your METTLER TOLEDO dealer for details of the available service options. Regular servicing by an authorized service engineer ensures constant accuracy for years to come and prolongs the service life of your balance.

8.1.1   Cleaning after overflow

If you overfill the pipetting container, or if water runs out next to the filling hole, a water film forms between the glass tube and the centering ring. This water film has a suction effect that can cause the liquid not to go into the pipetting container but instead to be sucked outside. Because of this, the measurement result may never become stable. Therefore, if such a water film forms, it must be removed immediately.

1 Close and remove the automated trap door.

2 Remove the glass cover.

3 Remove the centering ring and dry it.

4 Use an absorbent cloth to remove the water from the top part of the pipetting container.

5 If the water film was formed because the pipetting container is full, the container must be emptied.

See Emptying the pipetting container (page 26).

8.1.2   Emptying the pipetting container

If the pipetting container is full, the container must be emptied with the suction pump that was delivered with the balance.

26 Calibrating Pipettes

Damage of pump

Do not run the pump for too long after it is empty; it may damage the pump!

1 Open or remove the automated trap door.

2 Connect the suction pump to the power supply via the AC adapter.

3 Connect the suction tube (with the probe) to the input side ("IN") of the pump.

4 Connect the second pipe to the output side ("OUT") of the pump and place the free end of the pipe in a suitable drainage container.

5 Carefully introduce the suction probe into the pipetting container.

6 Switch the pump on by pressing the button and drain the pipetting container.

This should only take a few seconds.

8.2   Adjusting the balance

To ensure precise measurement results, the balance must be regularly adjusted. The XP26PC provides various possibilities for performing the adjustment either automatically or manually. You will find corresponding infor­ mation in the Operating Instructions – Part 3.

The supplied calibration kit contains all parts required for adjusting the balance and checking this adjustment with an external weight, with the exception of adjustment and test weights, which are available as accessories

"CarePac".

See Accessories (page 34).

Different parts must be installed depending on whether you are working with the small (1 g) or large (20 g) weight. Please observe the instructions included in the calibration kit.

How to perform the adjustment is described in the Operating Instructions – Part 3.

8.2.1   Verification of the balance adjustment

After a certain period of time (depending to customer’s particular requirements) the internal adjustment of the balance should be verified with an external weight using the calibration kit. The verification interval to be defined by the customer is meant to limit possible information campaigns or recall actions that may be manda­ tory in case of measurement errors.

Maximum admissible adjustment tolerances of the XP26PC for pipette calibration according to ISO 8655:

Application tolerances

Tolerance for 0.03 % (alert limit)

Tolerance for 0.10 % (action limit) measured with 1g E2

0.500 mg

1.500 mg

The adjustment tolerance values mentioned above ensure that all pipette calibrations meet the ISO 8655 requirements even in case the tolerances specified by the pipette manufacturer are up to five times more restric­ tive.

How to perform the verification is described in the Operating Instructions – Part 3.

8.2.2   Routine tests

In order to test the balance in accordance with GWP® (Good Weighing Practice™) routine tests must also be performed periodically to check repeatability and sensitivity. Standardized work instructions (SOP – Standard

Operating Procedure), which can be downloaded from the METTLER TOLEDO website, are available for both tests.

9.2   Explanatory notes for the METTLER TOLEDO AC adapter

The certified external power supply which conforms to the requirements for Class II double insulated equipment is not provided with a protective earth connection but with a functional earth connection for EMC purposes. This earth connection IS NOT a safety feature. Further information about conformance of our products can be found in the brochure "Declaration of Conformity" which is coming with each product.

In case of testing with regard to the European Directive 2001/95/EC the power supply and the balance have to be handled as Class II double insulated equipment.

Consequently an earth bonding test is not required. Similarly it is not necessary to carry out an earth bonding test between the supply earth conductor and any exposed metalwork on the balance.

Because the balance are sensitive to static charges a leakage resistor, typically 10 kΩ, is connected between the earth connector and the power supply output terminals. The arrangement is shown in the equivalent circuit diagram. This resistor is not part of the electrical safety arrangement and does not require testing at regular intervals.

11.1   MT-SICS interface commands and functions

Many of the instruments and balances used have to be capable of integration in a complex computer or data acquisition system.

To enable you to integrate balances in your system in a simple manner and utilize their capabilities to the full, most balance functions are also available as appropriate commands via the data interface.

All new METTLER TOLEDO balances launched on the market support the standardized command set "METTLER

TOLEDO Standard Interface Command Set" (MT-SICS). The commands available depending on the functionality of the balance.

For further information please refer to the Reference Manual MT-SICS downloadable from the Internet under u http://www.mt.com/xp26pc
