1   Introduction

Thank you for choosing a METTLER TOLEDO balance. 

The balances of the XP line combine a large number of weighing and adjustment possibilities with exceptionally convenient operation.

In this chapter you will be given basic information about your balance. Please read right through this chapter

carefully even if you already have experience with METTLER TOLEDO balances. Please pay special attention to

the safety warnings!

The different models have different characteristics regarding equipment and performance. Special notes in the

text indicate where this makes a difference to operation.

The XP line comprises a range of balances which differ from each other in relation to their weighing range and

resolution. 

The following features are common to all models of the XP lines:

● Glass draft shield with motorized drive and inner glass draft shield for precise weighing even in unstable

environments.

● Fully automatic adjustment "ProFACT" using internal weights.

● Built-in level sensor, illuminated level indicator and Leveling Assistant for fast and easy leveling.

● Built-in applications for normal weighing, statistics, formulation, piece counting, percent weighing, density,

differential weighing and LabX Client.

● Integral RS232C interface.

● Slot for second interface (optional).

● Touch-sensitive graphics terminal ("Touch screen") with color display.

● Two programmable sensors for hands-off operation ("SmartSens") to speed up frequently recurring tasks.

A brief word about standards, guidelines, and methods of quality assurance: The balances comply with usual

standards and guidelines. They support standard procedures, specifications, working methods, and reports

according to GLP (Good Laboratory Practice). In this connection, records of working procedures and adjustments become very important; for this purpose we recommend you to use a printer from the METTLER TOLEDO

range, since these are optimally adapted to your balance. The balances conform to the applicable standards

and guidelines and possess a EC declaration of conformity. METTLER TOLEDO is certified as manufacturer

according to ISO 9001 and ISO 14001.

4.6   Operating of the outer draft shield and the inner draft shield

4.6.1   Outer draft shield

The outer draft shield of your balance can be adapted to the environmental conditions and your weighing style,

as well as to the type of weighing and loading.

The doors of the outer draft shield can be opened and closed either by means of the [ ] key, the "SmartSens"

sensors, or by hand, see Operating Instructions – Part 2.

Try various different combinations by moving the 3 external handles up/inside and down/outside. We recommend you to set up the outer draft shield so that it only opens on the side where the balance is loaded. Your

balance then works faster, because there are fewer troublesome currents of air than when both doors of the outer draft shield are opened together.
1 For motorized door operation the handles must be connected.

Side doors: Handles turned toward the inside.

Top door: Handle down in horizontal position.

2 For manual door operation the handles must be disconnected.

Side doors: Handles turned toward the outside.

3 1

2

Important to know!

If you do not switch the balance off before you do the installation, the ProFACT function is not activated. 

Reason

Addition of the ErgoClip causes the dead-load tolerance range of the balance to be exceeded. The balance

therefore does not activate ProFACT, so as not to interrupt the assumed weighing operation. 

When this status icon appears in the display, it means: "The balance

wants to execute ProFACT" but cannot.

4.11   Installing the grid weighing pan cover

Note

For standard operation with conventional tare containers, we do not recommend using this weighing pan. Its

use may affect the stabilization time and degree of accuracy. The listed specifications are reached without a

weighing pan.

CAUTION

Hand injuries

Take care when handling the weighing pan, the corners and edges are extremely sharp!

Attention

With installed grid weighing pan cover, the balance does not switch to "Standby" mode!

1 For the installation, remove the grid weighing pan from the weighing chamber.

2 Gently press the cover onto the grid weighing pan.

3 Replace the grid weighing pan with the installed grid weighing pan

- The balance must be disconnected from the power supply.

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

- Never open the balance, terminal or AC adapter – they contain no components, which can

be cleaned, repaired or replaced by the user.

CAUTION

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.

1 To clean the weighing chamber thoroughly, swivel the glasses of the draft shields (inner and outer draft

shield) away from the balance and pull them out of their fastenings.

It may be necessary to turn the weighing pan slightly to remove it.

2 Carefully raise the front of the weighing pan and lift it out of the guide. 

3 Pull the drip tray away from the balance.

4 When you replace these parts, make sure they are in the correct position.

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.

7.2   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. 

Technical Data 29
30 Technical Data

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.

9.1   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/micro

9.2   Procedure for certified balances

Preface

Certified balances are subject to the national, legal requirements of "non-automatic balances".

Switching on the balance

● Switching on

• Immediately after being switched on, the balance displays 0.000.. g.

• The balance is always started up with the "Factory setting" unit.

● Switch-on range

• At maximum 20% of the type load, otherwise overload is displayed (OIML R76 4.5.1).

● Stored value as switch-on zero point

• It is not permissible to use a stored value as a switch-on zero point; the MT-SICS M35 command is not

available (OIML R76 T.5.2).

Display

● Display of the weight value

• The "e" certification value is always shown in the display and is specified at the model designation plate

(OIML R76 T.3.2.3 and 7.1.4).

• If the display increment is lower than the "e" certification value, this is variably displayed for the net, gross

and weighed tare. (Graying of the digits or certification brackets) (OIML R76 T.2.5.4 and 3.4.1).

● In accordance with guidelines, the tested display increment (certification value) is never lower than 1 mg

(OIML R76 T.3.4.2).

● At balances with d = 0.1 mg, the digits below 1 mg are displayed in gray. These digits in brackets are

printed. In accordance with legal metrology requirements, this illustration does not affect the accuracy of the

weighing results.

● Units of measurement

• The display and info unit are firmly set to g or mg (depending on the model).

• The following applies for the "Custom unit":

– No certification brackets.

– The following names are blocked, this applies to upper and lower case letters.

– All official units (g, kg, ct etc.).

– c, ca, car, cm, crt, cart, kt, gr, gra, gram, grm, k, kilo, to, ton.

– All names with "o" which can be replaced by a zero (0z, 0zt etc.).
● Identification of the weight display

• Gross, net, tare and other weight values are accordingly marked (OIML R76 4.6.5).

– Net for net when a tare value has been used.

– B or G for gross.

– T for the weighed tare.

– PT for the specified tare.

– * or diff for the difference between the net or gross.

● Info field

• The info weight value is handled metrologically in the same way as the weight value in the main display.

Printout (OIML R76 4.6.11)

● If a tare value is entered manually (PreTare), the PreTare value is always printed along with the net value

(PT 123.45 g).

● The printed weight values are identified in the same way as the weight value on the display. 

I.e. N, B or G, T, PT, diff or *, with differentiation.

Example:

Single-range balance.

N 123.4[5] g

PT 10.00 g ➔ for PreTare

G 133.4[5] g

DR balance with 100.00 g fine range.

N 80.4[0] g

T 22.5[6] g ➔ for weighed tare

G 102.9[ ] g

Balance functions

● Reset to zero

• The zero range is limited to a maximum of ± 2% of the full load (OIML R76 4.5.1).

● Tare

• No negative tare values are permitted.

• Tare immediate (TI) is not permitted, the MT-SICS TI command is not available (OIML R76 4.6.4).

● 1/xd

• e = d 

The 1/xd switchover is not permitted (OIML R76 3.1.2).

• e = 10d 

This is only permitted in the case of the 1/10d switchover.

• e = 100d

Only the 1/10d and 1/100d switchover are permitted.
