5.3 Internal Calibration
The Pioneer PA213 balance features internal calibration for optimal accuracy:
- Ensure the balance is level and stable, with no weight on the pan.
- Refer to the balance's on-screen menu or specific button sequence (usually involving a CAL button or menu option) to initiate internal calibration.
- The balance will perform the calibration automatically. Do not disturb the balance during this process.
- A confirmation message will appear upon successful completion.
5.4 Basic Weighing Procedure
- Turn on the balance and allow it to warm up for a few minutes (typically 15-30 minutes for precision balances).
- Press the [ZERO] or [TARE] button to set the display to zero.
- Place the item to be weighed on the center of the weighing pan.
- Wait for the stability indicator to appear, then read the weight value on the display.
- To weigh another item in the same container, place the container on the pan, press [TARE], then add the new item.
5.5 Selecting Environmental Parameters
The balance allows selection of environmental parameters for optimal adaptation to external conditions:
- Access the balance's menu settings (refer to the on-screen prompts or specific menu button).
- Navigate to the 'Environmental Settings' or similar option.
- Choose the setting that best matches your operating environment (e.g., stable, unstable, fast). This adjusts the balance's response time and stability filtering.
