I. INSTALLATION
1.1. Unboxing
Please carefully open the packing box, gently take out the balance and the contents in the box, and save the packing
materials for reuse.

1.2. Choice of 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.
1.3 Installation
Put the weighing pan on first, then plug the power adapter plug 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.

II. 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).

2.1.02 CAL.STEP
For BAS series balances, please warm up for 1 hour and wait until the balance is stable before calibrating.
Take BAS-2004 as an example, weighing no-load,
1) Press →0← to tare first, the balance will display 0.0000g,
2) Then press the CAL button, the display shows CAL-200 flashing,
3) At this time, put a "200g" calibration weight on the weighing pan, and after a few seconds, it will display "200.0000g"
calibration is complete.
Can be weighed.
