Introducing the XP/XS micro and ultra-micro balances
The XP/XS family of micro and ultra-micro balances 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/XS micro and ultra-micro balances:
– Glass draft shield for precise weighing even in unstable environments (XP models with motorized drive.
– Fully automatic adjustment using internal weights (“ProFACT” on XP models,“FACT” on XS models).
– Built-in level sensor, illuminated level indicator and Leveling Assistant for fast and easy leveling (XP models only).
– Built-in applications for normal weighing, statistics, formulation, piece counting, percent weighing, density, differential weighing ((XP
models only) and LabX Client.
– Integral RS232C interface.
– Slot for second interface (optional).
– Touch-sensitive graphics terminal (“Touch Screen”) with color (XP models) or monochrome display (XS models).
– Two programmable sensors for hands-off operation (“SmartSens”) to speed up frequently recurring tasks (XP models).
A brief word about standards, guidelines, and methods of quality assurance:The XP/XS balances comply with usual standards and guidelines.They support standard procedures, specifications, working methods, and reports according to GLP (Good Laboratory Practice), and
allow the creation of SOPs (Standard Operating Procedure). 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 XP/XS balances conform to the applicable standards and guidelines and possess a CE declaration of conformity.
METTLER TOLEDO is certified as manufacturer according to ISO 9001 and ISO 14001.

Cleaning and service
Periodically clean the weighing chamber, the housing, and the terminal of your balance
using the brush supplied with it.
To clean the weighing chamber thoroughly, pull the draft disk (which on the XP2U
���������
and
XP6U balances�������������������������������������������������������������������������
is made up of several parts) and the weighing pan vertically up and off
(it may be necessary to turn the weighing pan slightly to remove it)�.
When you replace these parts, make sure they are in the correct position.
Your balance is made from high quality,resistant materials and can therefore be cleaned
with a commercially available, mild cleaning agent.
Please observe the following notes:
– On no account use cleaning agents, which contain solvents or
abrasive ingredients, as this can result in damage to the terminal
overlay.
– 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.
Note: This also applies to the built-in clock battery in the balance.
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.

5.1.1
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 puposes. 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 or can be downloaded from www.mt.com.
In case of testing with regard to the directive 2001/95/CE 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 balances 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 figure below. This resistor is not part of the electrical safety
arrangement and does not require testing at regular intervals.

5.2.1
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 on.
• The balance is always started up with the “Factory setting” unit.
• Switch-on range
• A 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.
Technical data
20
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.

MT-SICS Interface commands and functions
Many of the balances and scales 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 depend on the functionality of the balance.
Basic information on data interchange with the balance
The balance receives commands from the system and acknowledges the command with an appropriate response.
Command formats
Commands sent to the balance comprise one or more characters of the ASCII character set. Here, the following must be noted:
• Enter commands only in uppercase.
• The possible parameters of the command must be separated from one another and from the command name by a space (ASCII 32
dec., in this description represented as /).
• The possible input for “text” is a sequence of characters of the 8-bit ASCII character set from 32 dec to 255 dec.
Note: For language-specific characters, please see Operating Instructions – Part 2, section 3.7.
• Each command must be closed by CRLF (ASCII 13 dec., 10 dec.).
The characters CRLF , which can be inputted using the Enter or Return key of most entry keypads, are not listed in this description, but it
is essential they be included for communication with the balance.
Example
S – Send stable weight value
Command
S
Send the current stable net weight value.
Response
S/S/WeightValue/Unit
Current stable weight value in unit actually set under unit 1.
S/I
Command not executable (balance is currently executing another command, e.g. taring, or timeout as stability was not reached).
S/+
Balance in overload range.
S/-
Balance in underload range.
Command
S
Send a stable weight value.
Response
S/S/////100.00/g
Example
The current, stable weight value is 100.00 g
