5. Usage Instructions (Practical Guide)

1) Installation Process

• Preparation: Clean equipment installation surface (flatness error ≤0.1mm/m), determine module quantity based on equipment weight and size (typically ≥3), and plan "fixed + floating + semi-floating" combination scheme (e.g., 3 modules: 1 fixed + 1 floating + 1 semi-floating).

• Module Fixing: Secure fixed modules to ground foundation with bolts, lightly fix floating/semi-floating modules (leaving 5–10mm displacement space), and ensure tight module-to-equipment contact without gaps.

• Wiring and Networking: Connect module signal wires to main junction box (intelligent modules directly parallel-connected) per specification: "red–power +, black–power –, green–signal +, white–signal –". Digital modules require unique address assignment through software to prevent signal conflicts.

• Protection Treatment: Outdoor installations require rain/sun protection covers; corrosive environments require anti-corrosion coating on non-loaded surfaces, waterproof junction box sealing, and proper marking.

2) Calibration and Debugging

• Zero Calibration: Power on and preheat 30 minutes, ensure unloaded equipment, execute zero calibration command achieving system zero output within ±0.002%FS. Excessive deviation indicates loose installation or foreign objects.

• Range Calibration: Use standard weights or force sources (loading ≥50% rated load), record system display deviation from standard values, and correct linear error through weighing instruments or software ensuring error ≤C3 allowable value (±0.02%FS).

• Eccentric Load Test: Place identical weights at different equipment positions, observe system reading consistency (deviation ≤±0.02%FS). Excessive deviation requires adjusting floating module displacement space for uniform load distribution.

3) Routine Maintenance

• Regular Inspection: Monthly surface cleaning (dust and oil removal), bolt tightness checks (especially fixed modules); quarterly wiring integrity verification, protective structure inspection, and zero-point recalibration.

• Fault Handling: Data drift investigation begins with power supply voltage verification (stable 12–24V DC) and ambient temperature checks. Abnormal readings trigger fault indicator light or software diagnosis for problem module identification. Select matching model/batch replacements requiring only zero-point recalibration.

6. Selection Method (Precise Matching Requirements)

1) Core Parameter Determination

• Range Selection: Single module range equals total equipment weight divided by module quantity (multiplied by 1.2–1), with reserved impact load and safety margin (e.g., 4 modules for 50t equipment: 15–19t single module range).

• Accuracy Level: Industrial metrology requires C3 level built-in sensors; laboratory/pharmaceutical applications need C2 level; general monitoring scenarios use C6 level. Dynamic weighing requires module response time ≤8ms.

• Signal Type: Traditional control systems use analog signal modules; smart factories/IoT scenarios employ RS485/Profinet digital modules matching existing PLC/instrument communication protocols.

2) Environmental Adaptability Selection

• Temperature: Standard scenarios (-20℃–60℃) use ordinary modules; high temperature (60℃–120℃) requires compensation type; low temperature (-40℃–-20℃) needs resistant modules.

• Medium: Dry environments use alloy steel; humid/food industries use 304 stainless steel; strong corrosive environments use 316L stainless steel or Hastelloy modules.

• Protection and Explosion-proof: Indoor dry environments require ≥IP67; outdoor/humid environments need ≥IP68; explosion-proof scenarios require corresponding level modules per regional standards.

3) Installation and System Compatibility

• Installation Mode: Fixed equipment uses "1 fixed + multiple floating" combinations; mobile platforms use fully fixed type. Equipment with thermal expansion requires floating modules comprising minimum 1/3 total quantity.

• Compatibility: Confirm module installation hole specifications match equipment support legs and signal output compatibility with existing control systems. Multi-module networking requires unified protocol models from same manufacturers to minimize integration complexity.

4) Additional Requirement Confirmation
