Setup

1. Unpacking: Carefully remove the balance and all components from the packaging. Verify that all items listed in the "What's in the Box" section are present.
2. Placement: Place the balance on a stable, level surface free from vibrations, drafts, and direct sunlight. Ensure adequate space around the unit for operation and ventilation.
3. Power Connection: Connect the provided power adapter to the balance and then to a suitable power outlet. The balance can also operate on batteries (not included) for portability.
4. Leveling: Use the adjustable feet and the spirit level (if present) to ensure the balance is perfectly level. This is crucial for accurate measurements.
5. Initial Power On: Press the ON/OFF button to power on the balance. Allow a brief warm-up period for stable readings.

Operating Instructions

Basic Weighing

1. Zeroing the Balance: Before placing any sample, ensure the display reads 0.00g. If not, press the Zero button to reset the display.
2. Placing the Sample: Carefully place the item to be weighed onto the center of the weighing pan.
3. Reading the Measurement: Wait for the reading to stabilize (indicated by a stability indicator on the display, if available). Read the weight displayed on the LCD.
4. Removing the Sample: Remove the item from the pan. The display should return to 0.00g or a stable negative value if tared.

Tare Function

The tare function allows you to weigh items in a container by subtracting the container's weight.

1. Place the empty container on the weighing pan.
2. Press the Tare button. The display will show 0.00g, and a "T" or "NET" indicator may appear.
3. Add the material to be weighed into the container. The display will show the net weight of the material.
