Setup and Installation

1. Unpacking and Inspection

Carefully remove the balance from its packaging. Inspect all components for any signs of damage that may have occurred during transit. Ensure all listed accessories are present.

• PS 200/2000.R1 Precision Balance unit
• Weighing pan
• Power adapter
• User manual (this document)

2. Placement and Leveling

Place the balance on a stable, level surface free from vibrations, drafts, and direct sunlight. Avoid locations near air conditioning vents, windows, or heavy machinery. Use the adjustable feet at the bottom of the balance to level the unit. The integrated spirit level (bubble level) on the balance indicates when it is perfectly level.

4. Initial Calibration

For optimal accuracy, it is recommended to perform an initial calibration after setup and whenever the balance is moved to a new location or experiences significant temperature changes. Refer to the balance's on-screen menu or the detailed technical specifications for calibration procedures.

Operating the Balance

Display and Keypad

The PS 200/2000.R1 features a backlit LCD display for clear readability and an intuitive keypad for easy operation. The display provides weight readings, unit indications, and menu prompts. The keypad includes dedicated buttons for common functions and programmable function keys (F1-F4) for customized shortcuts.

Basic Weighing Operations

• Power On/Off: Press the On/Off button to power the balance on or off.
• Zeroing: Press the -0- button to set the display to zero. This is typically done before placing any sample on the pan.
• Tare Function: Place an empty container on the weighing pan. Press the -T- button to tare the container's weight. The display will show zero, allowing you to weigh only the contents.
• Unit Selection: Press the Units button to cycle through available weighing units (e.g., grams, milligrams, kilograms).

Advanced Functions and Weighing Modes

The PS 200/2000.R1 balance offers a variety of advanced functions and weighing modes to suit diverse applications:

• Autotest: Self-diagnostic function.
• Dosing: For precise dispensing of materials.
• Percent Weighing: Measures weight as a percentage of a reference weight.
• Totalizing: Accumulates multiple weighings.
• Parts Counting: Counts individual items based on a reference weight.
• Checkweighing: Determines if a sample's weight falls within a specified range.
• GLP Procedures: Adherence to Good Laboratory Practice guidelines for data recording.
• Newton Unit Measurement: Measures force in Newtons.
• Statistics: Provides statistical analysis of weighing data.
• Animal Weighing: Stabilizes readings for unstable loads, such as live animals.
• Density Determination: Calculates the density of a substance.
• Under-Pan Weighing: Allows weighing of objects that cannot be placed on the pan, by suspending them below the balance.

Connectivity and Data Management

The balance is equipped with multiple interfaces for data transfer and integration:

• 2x RS232 Ports: For connecting to printers or other serial devices.
• USB-A Port: For connecting USB flash drives or other USB peripherals.
• USB-B Port: For connecting to a computer.
• Wi-Fi (Optional): For wireless data communication.

The system utilizes databases for storing information on operators (up to 10), products (up to 1000), weighings (up to 5000), tares (up to 100), and ALIBI memory (up to 100,000 weighings) ensuring data safety and continuity.

Maintenance

Cleaning

To maintain the accuracy and longevity of your balance, regular cleaning is essential. Always disconnect the power before cleaning.

• Use a soft, damp cloth with a mild, non-abrasive cleaning agent to wipe the exterior of the balance.
• The stainless steel weighing pan can be removed for thorough cleaning.
• Do not use harsh chemicals, solvents, or abrasive materials, as these can damage the balance's surfaces or internal components.
• Ensure no liquids enter the balance housing or display area.

Storage

When not in use for extended periods, store the balance in a clean, dry environment, away from extreme temperatures, humidity, and direct sunlight. It is advisable to cover the balance to protect it from dust.
