Safety
Representations & Symbols
Important instructions, which involve safety, are highlighted with the appropriate mark:
Safety recommendations
When using the weighing equipment in surroundings with increased safety
requirements, the corresponding regulations must be observed.
The weighing scale may only be used with the power adapter supplied.
Before connecting the power adapter to the scale, the user must ensure that the
operating voltage stated on the power adapter is compliant with the mains voltage.
If not, please contact Customer Service at the address above.
If the power adapter or its cable is damaged, the weighing scale must immediately be
disconnected from the electricity supply (pull out the power adapter).
If there should be any reason to believe that it is no longer safe to operate the scale, it
should be immediately unplugged from the electricity supply (pull out power adapter)
and secured against inadvertent operation.
In carrying out maintenance work, it is essential to follow the recommendations set out
in maintenance and servicing.
The weighing scale must not be operated in an area subject to explosion risks.
Care must be taken when weighing liquids to ensure that no liquid is spilled into the
inside of the scale or into connections on the rear of the equipment or the power
adapter. If liquid is spilled on the scale, it must immediately be unplugged from the main
electricity supply (pull out power adapter).
The weighing scale may be operated after it has first been inspected by a service
technician.
These operating instructions must be read by each user and should be easily
accessible at the workplace at all times.

Application & Conformity
The Following are instructions of how to correctly use the weight scale:
The weighing scale may only be used for the weighing of solid-materials and of liquids
filled into secure containers.
The maximum capacity load of the weighing scale must never be exceeded, otherwise
the weighing scale may be damaged.
In using the weighing scale in combination with other devices as well as with devices
produced by other manufacturers, the appropriate regulations for the safe use of the
relevant attachments and their application in accordance with instructions must be
observed.
The weighing scale has been manufactured and tested in accordance with the
standards and recommendations set out in the declaration of conformity.
The power adapter supplied for the weighing scale complies with the appropriate
electrical protection class.
The following applies to all MCT series weighing scales
Power supply:
Input: 110V or 230V AC (+/-15-20%); 50Hz to 60Hz
Output: 10v DC 500mA
Allowable ambient conditions
Temperature: 0°C - 40°C
Relative humidity: 25% - 85%, non-condensing

Getting Started
The scale is packaged in an environmentally-friendly carton, which provides optimum
protection for the balance during transportation.
We suggest that you keep the original packaging in order to avoid damage if you are
shipping or transporting the scale to a different location. It is also the best way to keep it
in the best conditions if it will not be used for an extended period of time.
In order to avoid damage, please follow the instructions provided below, when
unpacking the scale:
Unpack the scale carefully.
When outside temperatures are very low, the scale should be stored for a couple
hours and kept in its box in a dry room at normal temperature, so that no
condensation settles on the unit when opening the box.
Check the scale immediately after unpacking for any external visual damage. If
there is any damage on scale, contact customer service immediately.
If the scale is not to be used immediately after purchase, it should be stored in a
dry place where fluctuations in temperature are low. (Reference pg.15).
Read through these operating instruction, before you work with the unit and pay
attention to the Safety recommendations (reference Safety pg. 6).
Delivery
Inspect delivery for completeness immediately on unpacking all components.

Assembly & Installation
The weighing scale is delivered in a partly dismantled condition. Assemble the individual
components in the following sequence:
Place your machine on a level, clean, and dry surface to obtain accurate
readings.
Place the plastic platter on top of the scale, flat side facing up so the platter
sits firmly on the machine with the four “legs” inserted into the corresponding
four receptacles.
Place the stainless steel platter on top of the plastic platter with the flat side
facing up.
Connecting the AC Adapter
The following Safety recommendations must be observed when connecting the balance
The Scale should only be connected to the mains voltage socket with the power adapter
supplied. Check before connecting the power adapter to the mains socket, that the
operating voltage stated on the power adapter complies with the local mains voltage.
If the operating voltage is not the same as the mains voltage, the power adapter must
not be connected to the mains socket and contact customer service.
Placement of Scale
The location in which the scale is placed is very important in order for the scale to work
to its full potential. Certain conditions can affect the capabilities of the scale, conditions
like: the presence of air flow, variations in temperature, and direct sunlight. Please
follow the recommendations given below in choosing a location to place your scale.
Place the scale on a solid, firm and preferably vibration-proof, horizontal base
Make sure that the weighing machine cannot be shaken or knocked over
Protect from direct solar radiation
Avoid drafts and excessive temperature fluctuations
Avoid placing the scale near or on any magnetic surfaces.
The scale is fitted with one bubble level, and adjustable feet for level-control that allow
for small height differences or any unevenness in the surface on which the balance is
placed.
The screw feet must be adjusted so that the air bubble is precisely in the center of the
sight glass of the bubble level (see Fig. 1)

MCT Operation Manual
12
Rev 3, 07.07.2016
Place the scale horizontally and keep the bubble inside the bubble level aligned with the
circle (Fig.1). In order to get exact measurements, the balance must be carefully leveled
after each re-location.

Maintenance & Service
For maintenance-work, the balance must be disconnected from the power supply
(remove power adapter plug from socket). Also ensure that the balance cannot be
connected to the power supply during the work by a third party.
Make sure that no liquid spills into the scale while performing maintenance work. If
liquid is spilled on the scale, it must be inspected by a service technician.
Regularly perform maintenance to the weighing pan and the weighing pan holder by
removing any dirt or dust from under the weighing pan and on the weighing scale
housing. Use a soft brush or a soft, lint-free cloth, moistened with a mild soap solution.
Never use solvents, acids, alkalis, paint thinners, scouring powders or other aggressive
or corrosive chemicals for cleaning; these substances can cause damage to the
surfaces of the scale housing.
