4 Basic instructions

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

Do not use the scale for dynamic weighing. If the amount of the weighed material is reduced or increased significantly, the scale’s “stabilizing and compensating” mechanism can result in displaying erroneous weighing results! (Example: slow outflow of the liquid from the container placed on the scale.) Do not subject the plate to long-term load. This 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 explosion-proof. Never introduce any structural modifications to the scale. This may result in displaying 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 Warranty

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, liquids 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.

4.4 Testing equipment super vi s ion

Within the quality assurance system, you must check the technical measurement properties of the scale and possibly of the available reference weight regularly. To 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).

7 Unpacking, positioning and start-up

7.1 Installation plac e, operat ion place

The scales are designed to ensure reliable weighing results in standard operating conditions. The choice of a correct scale location ensures its accurate and fast operation.

This is why you should follow the following rules in the location site:

• 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 direct draft present at open windows and doors.

• Avoid impact when weighing.

• Protect the scale from high humidity of air, vapors and dust.

• Do not expose it to long-term heavy moisture. Any forbidden condensation of

the air moisture on the device may occur when a cold device is placed 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.

28 TALJG_A/TALSG_A/TPLJG_A/TPLSG_A-BA-e-2112

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.

7.5 Operator language selection

When the device is shipped, German is the preset display language. To set other languages, see chapter 11.11.

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.

8 Adjustment

As the standard gravity value is not the same in every spot on Earth, every scale 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 has not already been subject to factory adjustment in its location). Such an adjustment process should be carried out during the first start, following 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 scale adjustment in the weighing mode.

 Ensure stable environmental conditions. The heating time is required for the

stabilization (see chapter 1).

 Ensure there are no objects on th e scale pl at e.  Adjustment report printout, see chapter 8.6.

8.2 Automatic adjustment using the internal weight

Factory setting in the models in the verifiable setting (ALJ/PLJ)

The automatic adjustment using the internal weight is started automatically:

• when the scale was disconnected from the mains,

• after the ON/OFF button is pressed in the stand-by mode,

• after the temperature is changed by 1.5 degrees Celsjus for the non-

loaded scale plate / zero indication (this prevents adjustment when a series of measurements is performed)

• after 20 minutes, for the non-loaded scale plate / zero indication (this prevents adjustment when a series o f measurements is performed).

The automatic adjustment function is always on. However, it is always possible to carry out manual adjustment (by pressing the CAL button) using the internal weight, see chapter 8.3.

Automatic adjustment course:

The <Cal 25> symbol informs about the approaching adjustment.

In that time, the user should finish weighing. The countdown starting from 25 s starts [CAL 25] → [CAL 0]. During that period of 25 s, the adjustment can be stopped and delayed for 5 minutes,

pressing the ON/OFF button. As a result, the scale will be switched back to the weighing mode, e.g. to complete the ongoing measurement.

Seal location (PLJ models)

General information: According to the Directive 2014/31/EU, the scales must be verified if they are used in the following way (legally determined scope):

a) for commercial purposes when the goods’ price is determined by weighing

them,

b) to produce medications in pharmacies and also for analyses in medical and

pharmaceutical laboratories, c) for official purposes, d) for manufacturing finished packagings.

In the case of any doubts, contact the local Office of Measures. Guidelines concerning verification

The scale which is marked verifiable in the technical specification holds a type approval certificate in force in the European Union. If the scale is to be used in the above-mentioned area requiring verification, it must be verified and its verification must be renewed on a regular basis. Re-verification of the scale is carried out in line with the regulations in force in a given country. E.g. in Germany the scale verification validity period is usually 2 years. Always follow the regulations in force in the country of use! Once the verification process is completed, the scale is sealed in the determined position.

The <Piece counting> application enables to count many pieces placed on the scale plate. Before it is possible to count pieces using the scale, you should determine the average weight of an individual part (unit weight), the so-called reference value. For that purpose, place a specific number of counted parts on it. 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 part, the number of pieces will be counted. The following rule applies: The higher number of the reference pieces, the higher the accuracy of counting.

Density is the weight [g] to volume [cm3] ratio. The weight is obtained by weighing a sample in the air. The volume is determined based on the hydrostatic lift [g] of the sample immersed in a liquid. Density [g/cm3] of that liquid is known (Archimedes’ principle). Density is determined using the equipment for the under-scales weighing hanger or a kit for the density determination.

The optional density determination kit facilitates the density determination:

The ionizing unit has blades supplied with high voltage. In their immediate vicinity, there are ions generated with a positive and negative charge as a result of corona discharge. The ions are attracted by the weighed material with static charge, neutralizing the interfering static charge. This eliminates also forces falsifying weighing (e.g. the false weighing result, drifting weighing value).
