2. Nastavení a instalace

2.1 Vybalení

Opatrně vyjměte váhu z obalu. Zkontrolujte všechny součásti, zda nevykazují známky poškození. Uschovejte si originální obal pro budoucí přepravu nebo skladování.

2.2 Umístění

Place the balance on a stable, level surface free from vibrations, drafts, and direct sunlight. Avoid locations near heat sources, air conditioning vents, or heavy machinery. Ensure sufficient space around the balance for operation and maintenance.

2.3 Assembly of Weighing Chamber

The AS X2 PLUS analytical balance features an ergonomic mechanical design with a spacious weighing chamber. The dual-CLICK system allows for tool-free assembly and disassembly of the weighing chamber components, including the rimless panes and aluminum base, ensuring stability and reliability.

2.5 Připojení napájení

Connect the provided power adapter to the balance's DC input port and then to a suitable power outlet (100-240V AC, 50/60Hz). The balance requires 12V DC, 0.8A power supply, with a maximum power consumption of 4W.

2.6 Komunikační rozhraní

The balance offers various communication interfaces for data transfer and connectivity:

• RS232: For serial communication with external devices.
• 2x USB-A: Pro připojení periferií USB.
• USB-B: Pro připojení k počítači.
• Wi-Fi: Pro bezdrátové síťové připojení.
• Ethernet: Pro připojení k kabelové síti.

3.3 Základní postup vážení

1. Ujistěte se, že je váha v rovině a stabilní.
2. Power on the balance and allow it to stabilize.
3. Place an empty weighing vessel (e.g., beaker, petri dish) on the weighing pan.
4. Press the "Tare" button to zero the display.
5. Carefully add the substance to be weighed into the vessel.
6. Wait for the reading to stabilize. The stable weight will be displayed.
7. Zaznamenejte měření.

3.4 Weighing Modes and Functions

The balance supports various weighing modes and functions, including:

• Formulace: For preparing mixtures with multiple components (up to 18 functions).
• Percent Weighing: For determining the percentage of a sample relative to a reference weight.
• Počítání dílů: For counting a large number of identical items.
• Animal Weighing: For stabilizing readings with moving subjects.
• Stanovení hustoty: For calculating the density of solids or liquids.
• Kontrolní vážení: For verifying if a sample's weight falls within a specified range.
• Automatický test: Self-diagnostic function.
• Dávkování: Controlled dispensing.
• Newton unit measurement: For force measurement.
• Under-pan weighing: For weighing objects that cannot be placed on the pan.
• Ambient conditions monitoring: Integrated sensors for environmental data.
• GLP Procedures: Good Laboratory Practice compliance.
• Statistical Quality Control (SQC): For process control.
• ALIBI Memory: Ensures data safety by recording up to 100,000 weighings.

Access these functions via the touch screen interface. Refer to the on-screen menus for detailed instructions on each mode.

3.5 Touch-Free Operation (IR Sensors)

The balance features two programmable IR sensors for touch-free operation, allowing users to execute common functions (e.g., tare, print) without physical contact, enhancing hygiene and workflow efficiency.

4. Údržba

4.1 Čištění

Regularly clean the balance to maintain accuracy and prolong its lifespan. Use a soft, damp cloth with a mild, non-abrasive cleaning agent. Do not use harsh chemicals or immerse the balance in water. The weighing pan and other removable components can be cleaned separately.

The weighing pan and centering ring are made of stainless steel, and the balance housing is plastic, with glass draft shield components. These materials are resistant to common laboratory cleaning agents.

4.2 Kalibrace

The balance features internal automatic adjustment (calibration). For optimal accuracy, perform regular calibration checks using certified external weights. Refer to the balance's on-screen menu for calibration procedures.

4.3 Skladování

When not in use for extended periods, store the balance in a clean, dry environment, preferably in its original packaging. Ensure the balance is powered off and disconnected from the power supply.
