2. Setup

Follow these steps to set up your Ohaus NVT6200 Portable Balance:

1. Unpacking: Carefully remove the balance and all accessories from the packaging. Retain the packaging for future transport or storage.
2. Placement: Place the balance on a stable, level surface free from vibrations, drafts, and direct sunlight. Ensure the surface can support the weight of the balance and any items to be weighed.
3. Power Connection:
   • AC Adapter: Connect the supplied AC adapter to the balance's power input and then to a suitable power outlet.
   • Battery Power: For portable use, install four "C" batteries (not included) into the battery compartment located on the underside of the balance. Ensure correct polarity.
4. Leveling: Use the adjustable feet and the spirit level (if present, typically near the display) to ensure the balance is perfectly level. Adjust the feet by turning them clockwise or counter-clockwise until the bubble in the spirit level is centered.
5. Initial Power On: Press the ON/OFF button to turn on the balance. Allow a brief warm-up period for optimal performance.

3.1 Basic Weighing

1. Turn on the balance by pressing the ON/OFF button.
2. Wait for the display to show "0.00 g" (or the last used unit) and the stability indicator to appear.
3. Place the item to be weighed on the center of the weighing pan.
4. Read the stable weight value displayed on the LCD.
5. Remove the item from the pan.

3.2 Taring (Zeroing)

To weigh an item in a container, use the Tare function:

1. Place the empty container on the weighing pan.
2. Press the TARE button (or use the touchless sensor if configured). The display will return to "0.00 g".
3. Add the item to be weighed into the container. The display will show the net weight of the item.

3.3 Changing Weighing Units

The NVT6200 supports multiple weighing units. To change the unit:

• Press the UNIT button (or use the touchless sensor if configured) repeatedly to cycle through the available units (g, kg, N, oz, ozt, dwt, lb, lb/oz, ct, grain).
• Stop when the desired unit is displayed.

3.4 Using Weighing Modes

The balance offers various application modes:

• Weighing: Standard weight measurement.
• Parts Counting: For counting a large number of identical items based on a reference weight.
• Percent Weighing: For measuring the weight of a sample as a percentage of a reference weight.
• Checkweighing: For checking if a sample's weight falls within a specified target range.

Refer to the detailed user manual for specific instructions on configuring and using each weighing mode, typically accessed via a MODE or FUNCTION button.
