This guide outlines the standard operating procedures for the Lahti Precision WB900, a high-performance weighing and dosing controller often used in industrial environments. Since this device is typically part of a larger system (like a batching plant or scale), these steps cover the core interface and maintenance basics. 1. Daily Startup and Interface Basics
While there is no single document titled "lahti precision wb900 kayttoohje best," the is a specific weighing controller model produced by Lahti Precision (now part of the Scale Solutions
4. Calibration (Kalibrointi)
Calibration is recommended before critical measurements or if the balance has been moved. You will need a calibrated external weight (typically provided with the unit or purchased separately) or use the internal calibration motor if equipped.
The WB-900 features Keyboard Calibration, meaning physical internal adjustments are rarely necessary. Most parameters are protected by a password to prevent unauthorized changes.
| 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. |
The device includes time and date memory, which is essential for audit trails in commercial applications. Functional Versatility:
To get the most out of these features, you need the correct settings—hence the need for the official käyttöohje.
The WB900’s versatility is its primary strength. It supports a wide range of industrial applications, including: Logistics: Reception and dispatch of goods and vehicle scales. Production:
For users looking for higher memory capacity (such as 10 totalizing counters or product code memories), the WB-902 variant is the recommended upgrade from the base WB-900. WB-900 AND WB-902
