Calibration failure symptoms: Inconsistent readings, residual imbalance after adding weights, or error code Err 5.


The Lahti Precision WB-900 is a high-precision digital weight indicator designed for demanding industrial weighing tasks. Known for its reliability in harsh environments, it is commonly used in weighbridges, vehicle scales, and tank or silo weighing systems.

Below is a guide to the key functions and setup parameters based on technical documentation for the WB-900 series. Key Technical Specifications Accuracy Class: Class III, 10,000 e (EN 45501 / OIML R76). Internal Resolution: Up to 2,000,000 counts. Operating Temperature: -10negative 10 +40∘Cpositive 40 raised to the composed with power C Display: 7-segment LED display with 14 mm digit height.

Protection: Robust enclosure designed for humidity and electrical interference resistance. Core Operating Functions

The WB-900 uses a tactile membrane keyboard for all primary operations. Zero Setting: Used to reset the scale to zero when empty.

Taring: Allows for the subtraction of container weight (net/gross toggle).

Hold Value: Used for recording and monitoring specific peak weight values.

Limit Values: The WB-900 model allows for the preset of limit values for automated control. Calibration and Setup (Quick Guide)

The WB-900 features Keyboard Calibration, meaning physical internal adjustments are rarely necessary. Most parameters are protected by a password to prevent unauthorized changes.

Password Entry: Access the setup menu by holding specific function keys (Shift/Esc) and entering the protected code. lahti precision wb900 kayttoohje best

Corner Adjustment: The system includes an automatic corner adjustment feature to ensure accuracy regardless of where the load is placed on the platform. Linearity: The device supports high linearity (error

), which can be fine-tuned during the initial dead-weight calibration process. Connectivity and Integration

The indicator is designed to serve as a hub for industrial automation:

Serial Interfaces: Supports RS-232C, RS-485, or Current Loop for connecting to PCs or PLC units.

Analog Output: Optional 0/4–20 mA output for integration into control loops.

Control I/O: Includes four control inputs and outputs for managing weighing operations automatically. Maintenance Tips

Memory Protection: The unit uses a battery-backed SRAM with an estimated 10-year life to preserve calibration data and settings during power loss.

Interference: While the unit is shielded, ensure load cell cables are kept away from high-voltage power lines to maintain the highest signal integrity (minimum signal

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
