2.2 Working Environment

If conditions do not permit, the working environment should be selected according to the following requirements:

(1) The studio should be kept clean and dry;

(2) The balance should be placed on a stable and fixed workbench (it is recommended to be placed on a marble platform);

(3) The workbench should be far away from doors and windows, so as to reduce the influence of airflow caused by opening windows and doors;

(4) The workbench should be set up where there is little vibration interference. The surroundings of the room are less affected by vibration, and the ideal position of the workbench should be placed;

(5) The balance should be placed in a place that is easy to cause temperature changes,such as avoiding direct sunlight and away from heaters;

(6) Please avoid connecting with large machines or devices with interference, and avoid the interference of other devices;

(7) The dry environment is prone to static electricity, so corresponding measures can be taken to avoid the influence of static electricity on weighing.

(8) Keep the balance away from objects and equipment with magnets or capable of generating magnetic fields;

(9) The balance shall not be used in areas with explosive danger;

(10) Do not use the balance for a long time in a high humidity or high dust environment;

(11) When the balance is transferred from a colder environment to another warmer environment, the moisture in the air will be on the balance.The internal condensation of the weighing system affects the accuracy and reliability of weighing. In order to eliminate the influence of moisture condensation, the balance can be left unplugged at room temperature for 2 hours before use.

2.3 Installation

Put the weighing pan on first, then plug the power adapter into the balance, then plug the power supply (input voltage 220V) and wait for it to turn on. Please place the weighing pan correctly, otherwise a prompt will appear that the weighing cannot be performed.

3. Operation

Before using the balance, the balance should be placed horizontally. Use the adjustment foot screw at the bottom of the balance to adjust the level, so that the bubble in the leveler is adjusted to the center of the circle, and then quickly press the POWER button to turn on the display. To ensure accurate weighing of the balance, please ensure that the balance is fully warmed up (the recommended warm-up time is one hour).

3.1 Calibration The Balance

3.1.01 Cal Weight (0IMLF1)

Table 2

3.1.02 Cal.Step

For BFT series balances, please warm up for 1 hour and wait until the balance is stable before calibrating.

Take BFT-1201 as an example, Before calibration, ensure that the scale is empty and free of any loading material.

5. Maintainence

This series multifunctional electronic balance is a precision mechatronics intelligent measuring instrument, so it must be treated as seriously and carefully maintained as other precision instruments.

1. Do not use sharp objects (such as pencils, ball-point pens) to press keys, only use your fingers to press keys;

2. Be careful not to let objects fall from a high place on the weighing pan, so as not to damage the weighing mechanism;

3. Do not expose the balance to high humidity or dusty environment for a long

time;

4. After the balance is used up, it is best to cover it with a cover to prevent dust intrusion;

5. When weighing powder and fine particles, please use it with the container to avoid dust and particles falling into the load cell under the weighing pan;

6. Please wear gloves when calibrating with weights, and do not take the weights directly with your hands;

7. Keep the balance clean and dry. Matters needing attention when cleaning:

Before cleaning, unplug the power supply;

Do not use corrosive cleaning agents (such as solvents). Use a lint-free soft cloth dipped in water and then some neutral detergent (soap) for cleaning.

When cleaning, be careful not to let water drop into the balance;

After cleaning, wipe the balance carefully with a soft, dry, lint-free cloth.
