1 Setting up the scale
Please read these operating instructions carefully and follow them exactly! If you find that any items are missing or incorrect, or if
you have any other problems with your scale, please contact your authorized METTLER TOLEDO representative.
1.1 Unpacking and checking the delivered items
Remove the scale and accessories from the packaging. Check that all items have been delivered. The package should include:
– Viper scale
– Platter (and draft shield on 6lb version)
– Operating instructions (this document)
– Labels for noting the weighing range and readability after setting
– Special accessories per packing list (if applicable)
1.2 Safety and environment
To ensure safe, environmentally compatible operation of your scale, please observe the following:
The scale is designed for operation in hazardous areas Class I, Division 1, Groups A, B, C, D. However, for
this purpose the scale must be connected to a certified METTLER TOLEDO power supply unit:
– PSUx power supply unit (if not using the data interface)
– PSU power supply unit (if using the data interface)
The installation instructions for the respective power supply unit must always be observed and followed.
The regulations for operating equipment in hazardous areas must always be observed and followed.
Never undo the fastening screws of the load plate support under the platter!
Never insert a rigid object under the load plate support when the platter is removed.
Do not open the scale by undoing the screws in the base.
Use only the recommended accessories and peripherals.
Treat the scale carefully. It is a precision instrument. Avoid knocking the platter or placing excessively heavy
loads on it.
Important if the Viper scale will be used in food processing areas: Those parts of the scale which may come
into contact with food have a smooth surface and are easy to clean. The materials used do not shatter and
contain no harmful substances.
Because of the danger of static charge, a protective cover may only be used if it is made from anti-static
material.
When disposing of the scale, observe the applicable environmental regulations.
Chapter 1: Setting up the scale

1.3 Selecting a location and leveling the scale
Choosing the proper location for your scale will guarantee high weighing accuracy!
Choose a stable, vibration-free, flat surface (this is especially important for highresolution scales and balances with METTLER TOLEDO MonoBloc technology). This
surface must be able to safely bear the weight of the fully loaded scale.
Pay attention to environmental conditions.
Avoid:
– direct sunlight
– strong drafts (e.g. from fans or air conditioning)
– excessive temperature fluctuations
– the use of radio equipment in close proximity to the scale.
Adjust the scale horizontally by turning the leveling feet. If there is a level indicator, the
air bubble must lie inside the inner circle.
Major changes of geographical location
Each scale is adjusted by the manufacturer for the local gravitational conditions (geo
value) of the geographical zone to which the instrument is shipped. If there is a major
change of geographical location, this adjustment must be corrected by a service
technician, or the scale must be readjusted. Certified scales must also be recertified in
accordance with applicable regulations for certification.

1.4 Connecting the power supply and grounding cable
To ensure protection against explosions, the scale may only be operated with either the PSUx or PSU power supply unit, and must
be connected to the building ground by a cable with a cross section of 1–4 mm2.
Important: When making the connection, always observe and follow the separate installation instructions for the PSUx or PSU power
supply unit respectively.
To connect the cable of the power supply unit and the grounding cable proceed as
follows:
Unscrew the screws in the back plate and remove the back plate.
Fasten the screwed connector on the blue cable of the power supply unit to the back plate
with the locking nut.
Connect the nine-core cable to the screw terminals of the scale according to the following
table.
Scale Power supply unit
No. Function PSUx PSU
1U1 white white
2 GND yellow yellow
3U2 green green
4 GND brown brown
5 Ubl gray black
6 TXD+ red red
7 TXD– blue blue
8 RXD– –– pink
9 RXD+ –– gray
10 NC black ––
11 NC pink ––
Replace the back plate and fasten it with the screws. When doing so, take care not to
trap any wires.
Using a cable with a cross section of 1–4 mm2 connect the grounding screw on the back
of the scale to the building ground. Make sure the grounding cable is correctly connected
to the scale and the building ground.
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, the scale must be adjusted/calibrateed by a service
technician after installing it. Note: Certified scales must be adjusted by an authorized
organization. Please consult your dealer.

This chapter explains how you switch the scale on and off, adjust the zero setting, tare the scale, carry out weighings, and record
weighing results.
2.1 Switching on/off and setting to zero
You switch the scale on and off by pressing the «On/Off» key.
After it has been switched on, the scale carries out a display test. When the weight
display appears, the scale is ready for weighing and is automatically set to zero.
Note: If necessary, you can use the «Zero» key to set the scale to zero at any time.

2.4 Taring options
At the factory, the scale is set so that taring is carried out using the «Tare» key as described in the previous section. However, other
taring options can be activated in setup (Section 3.4.2); these are described below.
2.4.1 Multiple taring
If the “Chain tare” function is activated, you can re-tare the scale at any time by pressing the «Tare» key. Each time the key is pressed,
the value in the tare memory is overwritten with the current weight value. This allows you to place an additional weighing container
on the pan at any time and tare it. Note: On noncertified scales, this function is activated at the factory; on certified scales, this function
is not available.
If the “Chain tare” function has been switched off in setup, only one single taring is allowed for each weighing operation. If you
nevertheless attempt to tare the scale a second time, the error message “No” appears. You can only tare again after the current
weighing result has been cleared with the «Clear» key or the display has been reset to zero using the «Zero» key.
2.4.2 Automatic taring
If the “Autotare” function is activated, the scale automatically interprets the first weight placed on the pan as the tare weight. When
weighing is complete and all items have been removed from the platter, after a few seconds, the tare value is cleared and the scale
is ready for the next taring and weighment. Note: The “Autotare” function is turned off at the factory. On noncertified scales, it can
be activated in setup; on certified scales, this function is not available.
2.4.3 Automatic tare clearance
If this function is activated, the tare value is automatically cleared when the weighing container is removed from the platter, provided
that a weighment has previously been carried out. Note: At the factory, automatic tare clearance is turned off. This function can only
be activated in setup if the automatic taring function is turned off.
2.5 Recording the weighing result
Pressing the «Print» key transmits the current weighing result via the interface to the
peripheral device (printer, computer). At the factory the interface is configured for connection of a printer. Refer to Section 3.6 for information about configuring the interface.
The example on the left shows a record of a weighment with tare. “G” indicates the gross
weight, “T” the tare, and “NET” the net weight.

3 Setup
You can use the setup mode to change the settings of the scale and to activate functions. This makes it possible to adapt the scale
to your individual weighing needs. To prevent incorrect operation during day-to-day work, setup is reserved for the supervisor and
can only be accessed with a password (Exception: Parts of the “Terminal” block can be accessed by the user, see Section 3.5.2).
3.1 Calling up the setup mode and entering the password
Press the «Print» key and hold it down until ...
... the prompt to enter the password appears.
The password comprises a series of keystrokes. At the factory, the password for the
supervisor has been set to «Zero» «Zero» «Zero». We recommend you to replace this
password with one of your own as soon as possible (Section 3.5.2).
To call up the setup mode using the password set at the factory, briefly press the «Zero»
key three times.
Each keystroke you enter is shown in the display as a double horizontal dash.
Confirm the password with the «Print» key.
If you entered the password correctly, the first main block of the setup now appears.
Note:
– Enter the password as soon as you are prompted with “Code”; otherwise, the scale
returns to normal operation after a few seconds.
– If the password you entered is incorrect, an error message (“no”) appears, and
shortly after this you will be prompted to reenter the password.
– If you do not operate any key for approximately 3 minutes, the scale automatically
returns to weighing mode.
