Operation Guide
Basic Weighing
- Press the ON/OFF button to turn on the balance.
- Wait for the display to show '0.0' or '0.00' (depending on the selected unit) before placing any item on the weighing pan.
- Gently place the item to be weighed onto the center of the stainless steel weighing pan.
- Read the stable weight displayed on the LCD.
- Press the ON/OFF button again to turn off the balance when finished.
Tare Function
The tare function allows you to subtract the weight of a container, so only the net weight of the contents is measured.
- Place an empty container on the weighing pan.
- Press the TARE button (if available, otherwise ON/OFF button might serve this function by holding it briefly). The display will reset to '0.0' or '0.00'.
- Add the item to be weighed into the container. The display will show the net weight of the item.
Unit Conversion
The Ohaus YA102 balance supports multiple weighing units.
- With the balance on and displaying '0.0', press the MODE button repeatedly to cycle through available weighing units (e.g., grams (g), ounces (oz), carats (ct), grains (gn), etc.).
- Select the desired unit for your measurement.
Auto Shut-off
To conserve battery life, the balance is equipped with an automatic shut-off feature. If no weighing activity or button presses occur for a set period (typically 60-180 seconds), the balance will automatically turn off. This feature cannot typically be disabled.
Care and Maintenance
Proper care and maintenance will extend the life and accuracy of your Ohaus YA102 balance.
- Cleaning: Use a soft, damp cloth with mild detergent to clean the exterior of the balance. Do not use abrasive cleaners or immerse the unit in water. Ensure no liquids enter the internal components.
- Storage: When not in use, keep the balance in its protective clamshell case. Store it in a dry, cool place away from direct sunlight, extreme temperatures, and strong electromagnetic fields.
- Handling: Avoid dropping or subjecting the balance to excessive shocks, as this can damage the internal weighing mechanism.
- Batteries: Remove batteries if the balance will not be used for an extended period to prevent leakage and damage.
