This document describes the SUC-A & MAX-C Series Counting Scale manufactured by Shang Chuen Weighting Machine Co., Ltd.
Function Description
The SUC-A & MAX-C Series Counting Scale is a high-precision electronic counting scale designed for accurate weighing and counting of items. It utilizes a micro-processor combined with a sensitive strain gauge load cell, ensuring both accuracy and shock-proof performance.
Key functions include:
- Weighing: The scale can perform basic weighing operations. Users can weigh items directly or use a container by taring its weight.
- Counting: The primary function is counting. It supports two main methods for setting unit weight:
- Known Unit Weight: If the unit weight of an object is known, it can be directly entered into the scale.
- Unknown Unit Weight (Sampling): For items with unknown unit weight, users can place a sample quantity on the platform, input the quantity, and the scale will automatically calculate and display the unit weight.
- Accumulation: The scale allows for the accumulation of weight or quantity over multiple weighing sessions. This is useful for tracking total counts or weights of batches.
- Quantity Alarm: Users can set a target quantity, and the scale will trigger an alarm when the total counted quantity equals or exceeds the set alarm quantity.
- Zeroing: The scale can be zeroed to ensure accurate measurements, especially after placing or removing items.
- Taring: The tare function allows users to deduct the weight of a container, ensuring only the net weight of the items is measured.
- Backlight Control: The display backlight can be turned on or off, improving visibility in various lighting conditions.
- Automatic Print (Optional): The scale supports automatic printing, which can be toggled on or off.
- Manual Print (Optional): Manual printing is also available for specific data output.
Important Technical Specifications
While specific numerical specifications like capacity or division are not provided in the excerpt, the document highlights several important technical aspects:
- Load Cell: Employs a sensitivity force transducer strain gauge load cell, designed to be accurate and shock-proof. It boasts an "extremely high overloaded capacity."
- Processor: Features a micro-processor for efficient and precise operation.
- Display: Equipped with a large, clear, and easy-to-view liquid crystal display (LCD).
- Battery: Includes a no-leakage, long-life rechargeable battery, providing approximately 100 hours of operation per full charge. It also features a "Low battery warning" (bAt-Lo display).
- Construction: Features a die-casting sturdy construction, offering perfect protection against damage from overloading.
- Environmental Protection: The load cell is protected against humid environments, dust-proof, and corrosive-proof. The membrane switch is also dust-proof and corrosive-proof.
- Calibration: The manual provides a detailed 6-step calibration process, exemplified with a 30 kg scale, indicating the scale's ability to be calibrated to specific standard weights (e.g., 10 kg, 15 kg, or 30 kg for a 30 kg scale). This process involves setting up, adjusting zero points, placing standard weights, and inputting corresponding numbers based on a formula (
Standard weight unit * 【THE NUMBER】 = full scale weight).
Usage Features
The scale is designed for user-friendliness and precision:
- Direct Unit Weight Input: Allows direct input of unit weight, making it accurate and easy to operate when the unit weight is known.
- Automatic Unit Weight Recalculation: Automatically recalculates unit weight each time, contributing to more precise measured accumulation.
- Sampling Principle: Emphasizes the importance of selecting a suitable capacity (unit weight close to division) and quantity (larger sampling size for more accuracy, ideally at least 1/2 of total quantity) for optimal precision. It also features automatic re-averaging of unit weight to enhance precision, especially with small unit weights.
- Keypad Feedback: Provides a buzzer alarm with each keypad touch, confirming correct operation.
- Backlight Activation: The backlight automatically turns on when any key is pressed or something is placed on the scale, enhancing visibility.
- Accumulation Recall and Clear: Users can recall accumulated data ("MR") and clear it ("MC") as needed.
- Quantity Alarm Setting: The quantity alarm function is straightforward to set ("CK" to enter "Set-Ch", input quantity, then "WS" and "CK") and cancel ("CK", then "CE", "WS", "CK").
Maintenance Features
The manual outlines several important maintenance guidelines to ensure the longevity and performance of the scale:
- Cleaning:
- If the scale is dirty, it should be wiped with a soft cloth slightly soaked with neutral detergent.
- A protection cover is included as a standard accessory for use in dirty environments.
- The platform can be cleaned with water, but it must be dried well before use.
- Battery Care:
- The rechargeable battery should be recharged after long periods of storage (every 3 or 4 months).
- The battery should be fully charged before use.
- General Handling Precautions:
- Never immerse the scale in water or other liquids.
- Avoid placing heavy metal items or other objects on the scale when not in use.
- Never leave the scale with something placed on the platform for extended periods.
- Avoid giving a shock to the platform.
- Environmental Protection: The design incorporates dust-proof and corrosive-proof features for the load cell and membrane switch, reducing the need for frequent specialized cleaning in these areas.
- Instruction Manual: Users are advised to read the instruction manual completely before operation and keep it for further reference to ensure proper usage and maintenance.
