4 Basic instructions (general information)
4.1 Intended use
The scale you bought is intended for weighing the weighed material. It should be considered a “non-automatic scale”, e.g. the weighed material should be carefully placed
manually on the scale plate center. The weight can be read after it has stabilized.
4.2 Non-intended use
The scale is not intended for dynamic weighing, e.g. for removing or adding small
amounts of the weighed material. The scale’s “stabilizing and compensating” mechanism can result i n display ing errone ous weighi ng results ! (Exampl e: slow out flow of t he
liquid from the container placed on the scale.)
Do not subject t he plat e to long-ter m load. T his may damage the weighing mechanism.
Avoid any scale impact and overload higher than the stipulated maximum load (Max),
deducting the tare from the existing load. This could damage the scale.
Never operate the scale in explosive atmospheres. The standard version is not explo-
sion-proof.
Never introduce a ny structural mo di fi cati o ns t o the scale. Thi s m ay result in dis play i ng
erroneous weighing results, violating the technical safety conditions, and also in scale
damage.
The scale should always be operated in line with the provided guidelines. Other operation ranges / areas require a written consent of KERN.
4.3 Guarantee
The warranty expires:
• if you fail to follow our guidelines included in the user manual;
• if you fail to use the device in line with the intended use;
• if you introduce any modifications or open the device;
• if the device gets damaged mechanically or damaged by the utilities, liqui ds and
ordinary wear and tear;
• if the device is not set correctly or the electrical system is not as required;
• if the weighing mechanism gets overloaded.

Protect all the parts, e.g. wind breaker, scale plate, power supply etc.
4.4 Testing equipment supervision
Within the quali ty assurance sys tem, you mus t check the technical meas urement properties of the scale a nd possibly of t he availabl e referenc e weight re gularly. T o that aim,
the responsible user should define a relevant cycle, as well as the type and scope of
such an inspection. The information on the supervision of the testing equipment, i.e.
scales, and the required reference weights, can be found on the home page of KERN
(www.kern-sohn.com). The reference weights and scales can be calibrated fast and
for a low cost in the KERN calibration laboratory (against the national reference) approved by DKD (Deutsche Kalibrierdienst).
5 Basic safety instructions

7 Unpacking, positioning and s tart-up
7.1 Installation place, operation place
The scales are design ed to ensure r eliabl e weighi ng result s in standard operati ng c onditions.
The choice of a correct scale location ensures its accurate and fast operation.
This is why you should follow the following rules when selecting the installation place:
• Place the scale on stable, flat surface.
• Avoid extreme temperatures and temperature fluctuations, occurring e.g. when
you place it at the radiator or in a place exposed to direct sun rays.
• Protect the scale from the dir ect dra f t pres ent at open windows and doors.
• Avoid impact when weighing.
• Protect the scale from high hu midi ty of air, vapour s and dus t .
• Do not expose it to long-term heavy moisture. Any forbidden condensation of
the air moisture on the devic e may occur when a cold device is place d in a much
hotter environment. In such circumstances, leave the device not connected to
the mains for 2 hours to adapt to the ambient temperature.
• Avoid static discharge from the weighed material and scale container.
If there are any electromagnetic fields, static discharge and unstable power supply,
high readout deviations (erroneous weighing results) may occur. In such circumstances, change the location.
7.2 Unpacking and check
Remove the device and accessories from the packaging, remove the packaging material and place the device in the target location. Check if all components included in
the delivery are present and not damaged.
Scope of delivery / standard accessories:

7.6 Connecting peripherals
Before you connect or disconnect any extra devices (printer, computer) to/from the
data interface, the scale should always be disconnected from the mains.
Use solely accessories and peripherals supplied by KERN with the scale, being perfectly compatible with it.
7.7 First start
To get accurate weighing results using electronic scales, ensure the scales achieves
the appropriate o perating temper ature (see “H eating time”, c hapter 1). Duri ng the heating time, the scale must be connected to the power source (the socket, rechargeable
battery or batteries).
The scale accuracy depends on the local standard gravity.
Always follow the guidelines in the “Adjustment” chapter.

• Ensure there are no obj ect s on the scal e pl at e .
7.8 Adjustment
As the standard gr avity value i s not the sa me in every s pot on Ear th, every di splay with
the scale plate connected should be adjusted, in line with the weighing rules resulting
from the laws of physics, to the standard gravity in the scale location (provided the
scale system has not already been subject to factory adjustment in its location). Such
an adjustment proces s should b e carri ed out during t he firs t start, fol lowi ng every location change and also in the case of any ambient temperature fluctuations. To ensure
achieving accurate measurement date, it is also recommended to carry out regular
display adjustment also in the weighing mode.
• Prepare the required adjustment weight, see chapter 1.
Whenever possible, adjust using the adjustment weight with the weight similar to the maximum load of the scale (the adjustment weight is recommended, see chapter 1). The adjustment may also be carried out using
weights with other nominal values or tolerance classes, but this is not optimal
from the measurement technique perspective. The adjustment weight precision must correspond to the interval [d] of the scale, though preferably it
should be a bit higher. For information concerning reference weights, see

9 Counting the number of pieces
Before it is possibl e to count piec es using th e scale, you s hould deter mine the aver age
weight of an indivi dual piece (unit w eight), the so-called reference v alue. To do i t, place
the specific number of pieces which the counting the number of pieces will be carried
out for. The scale will determine the total weight which will be divided by the number
of pieces, the so-called reference piece number. Next, based on the calculated mean
weight of an individual piece, the number of pieces will be counted.
• The higher number of the ref erence pi eces, the hig her the accuracy of counting the number of pieces.

Remove the weighed material. The subsequent weighed material can be added
only when the indication ≤ zero.
Place the second weighed material. Wait until the stabilization indicator is dis-
played, then press M. The number of pieces is added to the total memory. The
number of weighing procedures and the number of pieces are displayed for ca. 3
s intermittently with the currently placed weight.
Whenever required, add the subsequent weighed material as described above.
Load should be removed from the scale between consecutive weighing procedures.
This process may be repeated 99 times until you reach the scale weighing range.
Displaying the “total” value:
When zero is displayed, press M. The total number of pieces and the number of
weighing procedures will be displayed for ca. 3 s.

If the amount of the weighed material is reduced or increased significantly, the scale ’s “stabilizing and c ompensating” mechanism
can result in displaying erroneous weighing results! (e.g.: slow
outflow of the liquid from the container placed on the scale, evaporating processes).
When dosing with small weight fluctuations, it is recommended to
switch this function off.

choose from 0 d – 9 d
13 RS-232 interface
RS-232 ensures two-way dat a exchange betw een the scale an d external dev ices. Data
is sent asynchronously in ASCII code.
To ensure communication between the balance and the printer, the following conditions must be met:
• Connect the scale wi th the printer interfac e using the appropr iate cable. Troublefree operation is ens ured only when t he appr opri ate int erfac e cabl e by KERN i s
used.
• Communication parameters (e.g. transmission speed) of the scale and the
printer must be compliant.
