16. Troubleshooting

16-1. Checking the Balance Performance and Environment

The balance is a precision instrument. When the operating environment or the operating method is inadequate, correct weighing can not be performed. Place a sample on the pan and remove it, and repeat this several times. if the balance seems to have a problem with repeatability or to perform improperly, check as described below. If improper performance persists after checking, contact the local A&D dealer for repair.

Checking that the balance performs properly

Check the balance performance using the self-check function as described in "7. Weighing Speed Adjustment / Self Check Function".

An error display appears when a malfunction is found.

Check the balance repeatability using an external weight. Be sure to place the weight in the center of the weighing pan.

Check the balance repeatability, linearity and calibrated value using external weights with a known value.

Checking that the operating environment or weighing method is proper Operating environment

Is the weighing table solid enough?

Is the balance level? Refer to "3-1. Before Use".

Is the operating environment free from vibration and drafts?

Is there a strong electrical or magnetic noise source such as a motor near the balance?

Weighing method

Does the weighing pan touch the rim or anything? Is the weighing pan and pan support installed correctly?

Is the RE-ZEROkey pressed before placing a sample on the weighing pan? Is the sample placed in the center of the weighing pan?

Has the balance been calibrated using the internal mass (one-touch calibration)? Has the balance been warmed up for 30 minutes before weighing?

Sample and container

Has the sample absorbed or lost moisture due to the ambient conditions such as temperature and humidity?

Has the temperature of the container been allowed to equalize to the ambient temperature? Refer to "3-2. During Use".

Is the sample charged with static electricity? Refer to "3-2. During Use".

Is the sample of magnetic material such as iron? Caution is required for weighing magnetic materials. Refer to "3-2. During Use".

MC-10K, MC-30K specifications

The A&D MC-30K and MC-10K are highly regarded weighing scales that cater to diverse industrial and commercial applications. Renowned for their accuracy, durability, and advanced technological features, these models are ideal for users who require precision in measurement.

The MC-30K model offers a capacity of up to 30 kilograms, while the MC-10K is designed for loads of up to 10 kilograms. Both models are equipped with high-resolution load cells that provide outstanding accuracy and stability in measurements. The readability of 1 gram for the MC-10K and 5 grams for the MC-30K ensures that even the smallest variations in weight are captured effectively, making them suitable for activities ranging from laboratory analysis to quality control in manufacturing processes.

One of the standout features of these scales is their easy-to-read LCD display, which allows users to view measurements clearly, even in low-light conditions. The display is designed to provide quick and efficient readouts, minimizing wait times during the weighing process.

Both the MC-30K and MC-10K models incorporate advanced technology, including automatic calibration and tare functions, which enhance usability and accuracy. The automatic calibration feature ensures that the scales maintain their precision over time, while the tare function allows users to weigh items in containers without needing to account for the container's weight separately.

Durability is another major characteristic of these scales. Built with robust materials, they are designed to withstand the rigors of daily use in busy environments. Additionally, their compact design ensures that they occupy minimal space, making them suitable for various settings, including laboratories, warehouses, and retail outlets.

Convenience is amplified with the inclusion of RS-232 interface options for seamless connectivity to computers or printers, enabling easy data collection and reporting. The power-saving features of both models, including auto-off functionality, contribute to longer battery life, reducing the need for frequent replacements.

In summary, the A&D MC-30K and MC-10K scales are exceptional tools for anyone needing reliable and precise weighing solutions. With their advanced features, user-friendly design, and durable construction, they stand out as top choices for industrial and commercial weighing applications.
