3. Basic Weighing (Peruskäyttö)

Follow these steps for standard weighing:

1. Turn On: Press ON/OFF. The display will perform a self-test. Wait until the display shows 0.000 (or similar resolution).
2. Tare a Container:
   • Place your empty weighing boat or beaker on the pan.
   • Press TARE. The display will return to zero.
   • The indicator usually shows a "Net" or "Tare" symbol.
3. Add Sample: Carefully add your sample to the container.
4. Read: Wait for the stability indicator (often an arrow or a symbol like g stops blinking) to stabilize before recording the weight.

Part 7: Pro Tips to Be "The Best" Operator

These tricks are rarely in the official kayttoohje but are used by Lahti trainers.

1. The "Finnish Corner" wrap: For unstable loads (sacks/bags), manually jog the carriage to 50cm height, run 3 rotations, then start auto-cycle. This creates a "belt" at the load's center of gravity.
2. Film saving: If wrapping soft boxes, reduce the prestretch from 250% to 200% (change via DIP switch 2 inside the control box). You lose 5% film stretch but prevent 50% damage claims.
3. Winter mode: When warehouse temperature drops below 5°C, preheat the film roll with a space heater for 10 minutes. Cold film shatters. The manual doesn't tell you this—experience does.

2. Button Layout & Display (Ohjaimet)

Familiarize yourself with the main control panel: Turn On: Press ON/OFF

• ON/OFF: Turns the device on or enters standby mode.
• TARE / ZERO:
  • Short press: Resets the display to zero (useful when placing a container on the pan).
  • Long press: Often used to toggle between weighing units (e.g., grams to carats).
• CAL: Initiates the internal or external calibration sequence.
• MODE / FUNC: Cycles through operating modes (standard weighing, percentage weighing, counting mode).
• PRINT: Sends data to a PC or printer via the RS-232/USB port.

2. Navigating the WB900 Control Panel

The Lahti Precision interface uses a logical menu structure. According to the Käyttöohje:

| Button/Function | Action | | :--- | :--- | | F1 – Setup | Select measurement units (g·mm / oz·in), sensitivity, and rotor type (rigid/flexible). | | F2 – Calibration | Runs the calibration routine using a known trial weight. | | F3 – Measure | Starts the spin cycle and displays unbalance vectors (Angle + Amount). | | F4 – Split | Converts unbalance from two-plane to single-plane if geometry allows. |

8. Vianetsintä

• Laite ei käynnisty: Tarkista virtalähde ja sulakkeet.
• Epätarkat mittaukset: Kalibroi uudelleen, tarkista anturit ja varmista, että laite on tasaisella alustalla.
• Näyttöongelmat: Kokeile nollata laite; jos ei korjaannu, huolto.

1. Commissioning

Before turning on the scale, ensure the platform is stable and level. The WB900 often comes with adjustable feet. Use the bubble level (usually on the indicator or column) to ensure the scale is perfectly horizontal.
