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.
• 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.

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).
