1 Putting into service

Please read through these operating instructions carefully and adhere to them at all times. If you discover
that materials are missing or that the wrong ones have been supplied, or if you have any other problems
with your scale, please refer to the dealer or salesperson concerned, or if necessary to the METTLER
TOLEDO representative responsible.

1.1 Unpacking and checking contents

• Remove the scale and accessories from the packaging.

• Check for completeness. The basic scope of supply comprises:
– scale
– weighing pan
– AC adapter (only for models with integrated battery)
– operating instructions (this booklet)
– any special accessories as per packing list

1.2 Safety and environmental protection

• Do not use the scale in hazardous areas (unless it is clearly identi­fied as being approved for these areas).

• For service in wet areas or dusty environments, or if wet cleaning
is necessary, scales with IP 65 ingress protection must be used.
But even these scales must not be used in environments where
there is a risk of corrosion. The scales must never be drenched or
immersed in a liquid.

• If the power cord is damaged, the scale must no longer be operat­ed. Therefore check the cable regularly and ensure that a free space
of about 3 cm is left at the rear of the scale, so that the cable is not
kinked too severely.

• Never tamper with the retaining screws for the load plate support
underneath the weighing pan.

• When the weighing pan is removed, never insert a solid object
underneath the load plate support.

• It is not permitted to open the scale by removing the screws in its
base.

• Only use approved accessories and peripherals.

IP65

ca. 3cm

5

• Handle the scale carefully; it is a precision instrument. Blows on

the weighing pan must be avoided, and heavy overloads must not
be placed on it.

• Important instructions when using Viper scales in the food sector:

those parts of the scale can come into contact with food products
have smooth surfaces and are easy to clean. The materials used
do not splinter and are free from contaminants. In food processing
areas it is recommended that a protective cover (Section 4.5) is
used. This must be cleaned regularly, just like the scale itself.
Damaged or heavily contaminated protective covers must be
replaced immediately.

• When the scale is finally taken out of service, observe the current
environmental regulations. If the scale is equipped with a battery,
this contains heavy metals and therefore must not be treated as
normal refuse! Local regulations for disposing of environmentally
hazardous substances must be complied with.

1.3 Positioning and leveling the scale

The correct location is a decisive factor in ensuring accurate weighing
results.

– Choose a stable and vibration-free location (particularly important

for high-resolution scales using Mettler Toledo MonoBloc technol­ogy). Place the scale on a surface that is as horizontal as possible
and strong enough to bear its weight when fully loaded.

– Check the ambient conditions (Section 4.4).
– Avoid:

– direct sunlight
– strong drafts (e.g. from fans or air conditioning systems)
– excessive temperature fluctuations.

• Turn the adjustable feet so that the scale is horizontal. If a spirit level
is fitted, the bubble must be located within the inner circle.

Major changes in geographical location:
Every scale is set by the manufacturer to suit the local gravitational

conditions (geographical adjustment value) in the geographical zone
to which the instrument is supplied. If a major change of geographical
location takes place, this setting must be adjusted by a service
technician or a new setting made. Certified scales must in addition be
recalibrated in accordance with national certification regulations.

6

1.4 Connecting to power supply

• Before connecting the power supply plug or AC adapter (AccuPac
version), verify that the voltage stated on the model plate is the
same as the local power line voltage.

• Connect the power cord plug or the AC adapter plug to the supply,
then connect the AC adapter (AccuPac version) via the jack at the
rear of the scale.

Powering up the scale initiates a display test in which all the segments
and then the software version are briefly displayed. Once the decimal
zero appears in the display, the scale is ready to operate.

For maximum possible precision, adjust/calibrate the scale after
installing it (Section 3.2). Note: Certified scales must be adjusted by
an authorized organization. Please consult your dealer.

1.5 Battery operation

Scales with a built-in battery (AccuPac) can under normal operating
conditions work independently of the AC power line for about 20 hours
(MonoBloc version) or about 30 hours (strain gauge version).
Immediately the AC power supply is interrupted (by withdrawing the
power cord plug or if there is a power failure), the scale switches auto­matically to battery operation. Once the AC power supply is restored,
the scale reverts automatically to AC operation.

The battery symbol indicates the current discharge status of the
battery (1 segment corresponding to about 25% capacity). If the
symbol flashes, the battery must be recharged.

A discharged battery requires at least 8 hours until it is recharged.
During the charging process work with the scale can continue, but
under these conditions a longer charging time is needed.

The battery is protected against overcharging, and the scale can
therefore remain permanently connected with the AC power line
without any problems.

2 Weighing

This section describes how to switch the scale on and off, zero and tare it, weigh materials and record
the results.

2.1 Switching on and off and zeroing

• Briefly pressing the «On/Off» key switches the scale on or off.

The scale carries out a display test (Section 1.4). Once the weight
display appears, the scale is ready to operate and automatically
zeroed.

Note: When necessary, the scale can be zeroed at any time with
the «Ç» key.

2.2 Simple weighing

• Place the object to be weighed on the scale.

• Wait until the stability detector (a small ring in the bottom left corner
of the display) disappears, then ...

• ... read the indicated weight.

2.3 Weighing with tare

• Place the empty weighing container or packaging on the scale.

• Press the «#» key briefly to tare the scale. The zero display and
the “NET” (net weight) symbol appear. Note: If the automatic tare
function has been activated in master mode (Section 3.3), there is
no need to press the «#» key.

Important notice for verified weighing instruments in EC countries

Weighing instruments verified at the place of manufacture bear the preceding mark on the
packing label and a green “M” sticker on the descriptive plate. They may be set to work
immediately.

Weighing instruments which are verified in two steps have no green “M” on the descriptive
plate and bear the preceding identification mark on the packing label. The second step of the
verification must be carried out by the approved Mettler-Toledo service or by the W & M
authorities. Please contact your Mettler-Toledo organization.

The first step of the verification has been carried out at the manufacturing plant. It comprises all tests
according to EN45501-8.2.2.

Your scale can be configured, interrogated and operated from a PC via an RS232C interface.

Preconditions

The following preconditions must be fulfilled to achieve communication between the scale and
a PC:

– The scale must be connected to the RS232C interface of the PC by a suitable cable (see

Section 4.5) .
– The scale interface must be set at “Dialog” mode (see Section 3.4).
– A terminal program must be available on the PC (e.g. “Hyper Terminal”).
– The communications parameters (protocol, bits and parity, data transfer rate) must be set

at the same values in the terminal program and in the scale (see Section 3.4).

21

SICS command set

Your scale supports the Mettler Toledo Standard Interface Command Set (MT SICS), the SICS
commands as per “Level 0” and “Level 1” being implemented:

Commands MT-SICS Level 0

I0 Inquiry of all implemented MT-SICS commands
I1 Inquiry of MT-SICS level and MT-SICS versions
I2 Inquiry of balance data
I3 Inquiry of balance SW version and type definition number
I4 Inquiry of serial number
S Send stable weight value
SI Send weight value immediately
SIR Send weight value immediately and repeat
Z Zero
ZI Zero immediately
@ Reset

Commands MT-SICS Level 1

D Balance display
DW Weight display (Display show Weight)
K Key control
SR Send weight value on weight change (Send and Repeat)
T Tare
TA Inquiry/setting of tare weight value
TAC Clear tare value
TI Tare immediately

Detailed information on the interface commands is given in the “MT SICS Reference Manual”
(No. 705184, only available in English).

In addition to the standard commands, scale-specific SICS commands also exist to support
product-specific characteristics. These commands are not given in the “MT SICS Reference
Manual”, but in the documentation supplied with the individual scale. At the present time the
Viper scale supports one single specific command for specifying the record header. This
command is described below.

22

Specifying the record header

With this command you can define up to 5 lines, each with a maximum of 24 characters, which
is printed out at the head of every record. Normally, the company name and address are printed
on the record in this way. Specify the record header as follows:

• Ensure that the communication between the scale and the PC is in good working order.

• The command for defining the record header is I31_x, where “x” is the line number. Specify

the desired record header as shown in the following example (only the required lines need

be entered):

I31_1_"Mettler-Toledo GmbH" <CR><LF>

I31_2_"Unter dem Malesfelsen 34" <CR><LF>

I31_3_"D-72458 Albstadt" <CR><LF>

I31_4_"Telefon ++49/7431/14 0" <CR><LF>

I31_5_"Internet www.mt.com" <CR><LF>

Please observe the following:

– Every command line must be terminated with <CR><LF> (corresponding to the “Enter”,

“Return” or “ ˛” key on the PC keyboard). The command is then executed immediately.
To correct a line, this needs to be entered again completely.

– The “_” symbol signifies an empty space, and in the above example serves solely to clarify

the syntax. The quotation marks must be entered, as they indicate to the scale that they
enclose a text string and not a command.

– You can insert empty lines by entering an empty space instead of text.

Example: I31_2_"_" <CR><LF> . This defines line 2 as an empty line.
– By entering I31_x <CR><LF> (x = line number) you can interrogate the appropriate line.
– With the command I31_x_"" <CR><LF> (x = line number) you can delete the individual

line again.

• Once the record header has been completely specified (and you do not want to give any further

SICS commands), you can break the connection between the scale and the PC. Important:
for the scale to actually print out the record, the interface mode must be reset at “Print”, and
the setting “Header” must be activated (“On”) for the data to be transferred (“defStr”). A
description of these settings and a specimen record corresponding to the above example are
to be found in Section 3.4.
