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.
IP65
ca. 3cm
6
• Only use approved accessories and peripherals.
• 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 5.5) 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 5.4).
– 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.
Note: The Viper BC has a special filter that accelerates certain procedures (zeroing, taring, determining the reference weight for piece
counting) in a nontranquil environment. This inevitably means that
there is a slight loss of accuracy with the results. For high-precision
results care must be taken to ensure as tranquil and stable an environment as possible, so that the filter is not activated.
7
=000∆
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.
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 4.2). 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.
The bar graph at the bottom of the display shows how much of the
weighing range is being used and how much is still available (as
% of nominal scale capacity).
• Wait until the stability detector (a small ring at the left edge of the
display) disappears, then ...
• ... read the indicated weight.
• Pressing the «:» key causes the weighing result to be displayed
in control mode, i.e. with a higher resolution. After a few seconds
the normal weight display reappears automatically. Note: control
mode is not available if the maximum resolution has already been
selected in master mode (Section 4.3).

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 4.3), there is
no need to press the «#» key.
•
Place the material to be weighed in the container, then ...
• ... read the indicated net weight.
• Pressing the «≤ BG/Net» key causes the gross weight to be
displayed (the “B/G” symbol appears). After a few seconds the
scale automatically reverts to displaying the net weight.
2.4 Recording weighing results
• Press the «±» key to send the current weighing result to the
peripheral device (printer, computer) via the interface. Factory
default configures interface 1 for connection to a printer.
Please refer to Section 4.4 for instructions on configuring the
interface(s).
2.5 Special functions (master mode)
In addition to simple weighing functions and piece counting (Section 3), the scale also has additional options and settings that can be
activated in master mode (Section 4).

3 Piece counting
Not only can your scale weigh, it can also count. Several powerful functions available for piece counting
are described in this section.
3.1 Counting pieces into a container
• If you work with a weighing container, place this on the pan and
tare the scale with the «#» key.
• Enter the number of reference pieces in the instrument:
• If you have placed exactly 10 pieces in the container, press the
«Ref 10» key.
• If you have placed the number of pieces indicated in the display
above the «Ref n» key, press that key.
The scale now determines the average piece weight, following
which it displays the number of pieces.
• Now place further pieces in the container until the desired number
of pieces has been reached.
As it is unusual for all pieces to have exactly the same weight, piece
counting can be made considerably more accurate with the additional function “Automatic reference optimization" (Section 3.3).
The following numbers of reference pieces can be selected by holding
down the «Ref n» key: 1, 2, 5, 15, 20, 25, 30, 50 and 100 pieces,
as well as the “no” option (in this case the «Ref n» key has no
function).
With the «≤/<» key you can now toggle between piece counting
and weight display at any time.
If the number of pieces is currently displayed, pressing the «:» key
displays the reference piece weight (i.e. the weight of one single
piece) for 3 seconds.
If the weight is displayed, this can be shown at a higher resolution for
3 seconds by pressing the «:» key.
If “Adding mode” (Section 3.4) is activated, the minimum number of
reference pieces necessary with small components is ensured automatically.

3.2 Counting out pieces from a container
Counting out pieces from a weighing container differs in a few essentials from counting them in (Section 3.1):
• Place the full weighing container on the pan and tare the scale with
the «#» key.
• Remove the desired number of reference pieces from the container.
• Enter the number of pieces removed (reference definition) using the
«Ref 10» or «Ref n» keys (see Section 3.1). The scale then displays
the number of reference pieces removed with a minus sign in front.
Note: The functions “Automatic reference optimization" (Section
3.3) and “Adding mode” (Section 3.4) are also available for
counting out tasks.
• Remove further pieces until the desired number has been reached.
3.3 Automatic reference opitimization
Automatic reference optimization results in more accurate counting
results on piece counting duties. This function can be activated or
deactivated in master mode (Section 4.3). The factory default setting
is with automatic reference optimization active.
Automatic reference optimization requires no action on the part of the
operator. The “Auto Opt” symbol appears in the display when this
function is active.
Automatic reference optimization works both with “Counting in”
(Section 3.1) and “Counting out” (Section 3.2).
Functioning:
In order to optimize the calculated reference piece weight automati-
cally, a number of pieces less than or equal to the number of reference
pieces already on the pan are added to it. The message “Refopt”
appears in the display, and automatic weight optimization is carried
out. This process can be repeated several times.

3.4 Adding mode
Adding mode ensures that the number of reference pieces used on
piece counting duties is not too small, which could give rise to
inaccurate results. This function can be activated or deactivated in
master mode (Section 4.3). The factory default setting is with adding
mode inactive.
If you have activated adding mode and the number of pieces placed
on the pan is too small for accurate determination of the reference
weight, you are prompted to place more pieces on the scale (e.g. 5
pieces).
• Place the stipulated number of pieces on the pan. The scale then
determines the reference weight.
Adding mode works both with “Counting in” (Section 3.1) and with
“Counting out” (Section 3.2).
3.5 Piece counting with 2-scale systems
You can hook up your Viper scale to a second scale, e.g. a floor scale
for counting a large number of pieces that would exceed the capacity
of the Viper.
• In master mode select the Viper operating mode for connecting a
second scale. Proceed as follows (Section 4.4):
– “Ref ; 2”: if you want to use the second scale as the reference
scale.
– “Bulk ; 2”: if you want to use the second scale as the bulk
weight scale.
• The interface of the second scale must be set as follows:
– For Viper and Spider scales:
“Mode”: “Dialog” (9600 bd, 8b no parity, Xon/Xoff)
– For PB-S scales:
“Mode”: “Host” (9600 bd, 8b no parity, Xon/Xoff)
– For other METTLER TOLEDO products:
MT-SICS-compatible interface (9600 bd, 8b no parity, Xon/Xoff).
• When piece counting you can toggle between the two scales with
the «≤/;» key.
The scale symbol top right in the display indicates the active scale:
“; 1” = Viper scale, “; 2” = second scale.
When the second scale is active, you can zero and tare it with the
Viper «®» and «#» keys, respectively.

No valid reading from reference scale
This message is only given when piece counting with a 2-scale system.
Check the connecting cable between the scales and the interface
settings.
No calibration/adjustment
Disconnect the power cord plug and then plug it in again. (If operating
on the battery, switch the scale off and then on again.) If the error
message reappears, calibrate/adjust the scale (Section 4.2). If this
does not help, contact your dealer or local representative.
Reference piece weight too small
When defining the reference weight, the scale has found that the
resultant weight of one single piece is below the permissible limit.
Piece counting is not possible for articles as small as this.
Unstable weight reading when defining the reference weight
When determining the reference weight, the reading did not stabilize,
and the scale therefore cannot determine the reference weight of a
single piece .
1.Ensure a tranquil environment.
2.Ensure that the weighing pan is free to move.
3.Change the setting of the vibration adapter (Section 4.3).
EAROM checksum error
Disconnect the power cord plug and then plug it in again. (If operating
on the battery, switch the scale off and then on again.) If the error
message reappears, contact your dealer or local representative.
5.2 Cleaning instructions

5.6 Interface commands
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 5.5) .
– The scale interface must be set at “Dialog” mode (see Section 4.4).
– 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 4.4).
26
SICS command set
Your scale supports the Mettler Toledo Standard Interface Command Set (MT SICS), all 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
Commands MT-SICS Level 3R Standard
PW Inquiry/setting of the piece weight
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.
27
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 4.4.
To give your METTLER TOLEDO products an assured future:
