Konica Minolta CM-3700A-U Plus spectrophotometer

（4） White calibration board

The calibration data of the white calibration board should be measured at 23 ° C. To obtain the highest absolute measurement accuracy, calibration and measurement should be carried out at 23 ° C; Avoid scratching or staining the calibration plate with dirt; When installing the calibration board on the sample rack, it is prohibited to move it to prevent scratching; When not in use, cover with a lid to avoid exposure to external light.

（5） Target Mask

Do not touch the inner surface of the target mask (white coating surface) with your hands to prevent it from getting dirty or scratched; When not in use, it should be placed in the accessory storage space of the device to prevent exposure to external light.

（6） Power related

Turn off the power when the device is not in use; Use the designated AC adapter and connect it to a power outlet that meets the requirements; Use AC power supply with rated voltage (within ± 10% range); Ensure that the output plug of the adapter is not short circuited, otherwise it may cause fire or electric shock; Do not connect the adapter to overloaded circuits, and do not cover the adapter with cloth or other materials during use to prevent electric shock or fire; When removing the adapter from the device, first unplug the power cord from the socket, and then unplug the output plug.

Storage, cleaning, transportation, and maintenance

（1） Storage precautions

The equipment should be stored in an environment with a temperature of 0-40 ° C, a relative humidity of ≤ 80% (at 35 ° C), and no condensation. High temperature and humidity environments can affect the performance of the equipment. It is recommended to store it together with desiccants at or near room temperature.

Avoid storing equipment in direct sunlight or near heating devices to prevent malfunctions caused by high internal temperatures; When storing, prevent the device from condensing, and when transporting to the storage location, also be careful to avoid sudden temperature changes that may cause condensation.

Do not store equipment in environments with high dust, smoke, or chemical gases to prevent performance degradation or malfunction; When the device is not in use, a protective cover should be installed to prevent dust from entering the integrating sphere and affecting the measurement accuracy; Do not let the device have the target mask installed for a long time; Do not leave the device in the driver's cabin or trunk of the vehicle to prevent malfunctions caused by temperature and humidity exceeding the allowed storage range.

The white calibration board may change color when exposed to light, and should be covered when not in use; The target mask may change color when exposed to light. When not in use, it should be stored in the accessory storage space of the device to avoid light exposure, scratches, and dust accumulation; When the equipment is not in use for a long time, it should be stored properly in the transport packaging; When operating the opening and closing parts of the attachment storage space, be careful not to pinch it.

（2） Cleaning precautions

When the surface of the equipment is dirty, wipe it with a soft dry cloth, and do not use organic solvents (such as naphtha, diluents) or other chemical reagents for cleaning.

When there is dust or dirt on the lens or receiver window, use a dust blower to remove it, and do not use organic solvents or other chemical reagents; When the interior of the white calibration board, zero calibration box, or target mask (except for the inner white coating surface) is dirty, use a soft, clean dry cloth to wipe it. For dirt that is difficult to remove, use a cloth dipped in ethanol to wipe it. After the cloth is dirty, it needs to be cleaned. Organic solvents or other chemical reagents are prohibited from being used.

When the surface of the white coating on the inside of the target mask or the inside of the integrating sphere is dirty, it is necessary to contact an authorized service agency; If the above methods cannot remove dirt or equipment scratches, contact an authorized service agency; When the equipment malfunctions, it is prohibited to disassemble and repair it on your own, and authorized service agencies must be contacted.

（3） Transportation precautions

Before transporting the equipment, it is necessary to remove the target mask and install a protective cover to protect the sample measuring components (integrating ball opening); The equipment weighs approximately 18kg and needs to be operated by two or more personnel when moving (including transporting) the equipment.

Packaging materials must be used when transporting equipment to reduce vibration and impact; When sending the equipment for repair, the equipment and all accessories must be packaged and sent out.

（4） Maintenance and Inspection

To ensure measurement accuracy, the equipment should be inspected once a year. For specific inspection matters, please contact the nearest authorized service agency of Konica Minolta.

（5） Disposal methods

Equipment, all accessories, and packaging materials must be properly disposed of or recycled in accordance with local laws and regulations to ensure compliance with environmental protection and relevant regulations.
