4.2 Calibration
Regular calibration is crucial for maintaining accuracy, especially after moving the scale or significant temperature changes. Refer to the specific calibration procedure in your scale's detailed manual, typically involving a known calibration weight.
- Ensure the weighing pan is empty.
- Press the Cal button (often marked with 'Cal' or a similar symbol).
- Follow the on-screen prompts to place the specified calibration weight on the pan.
- Wait for the scale to stabilize and display '0.0' or 'Pass'.
4.3 Weighing Procedure
- Ensure the scale is on and displaying '0.0'.
- Gently place the item to be weighed in the center of the weighing pan.
- Wait for the display to stabilize. The stable weight will be shown.
- Remove the item from the pan.
4.4 Unit Conversion
To change the weighing unit (e.g., from grams to ounces or carats), press the Δ/F button (often marked with 'Δ/F' or 'Unit'). Each press will cycle through the available units (grams, oz, dwt, ct, lb, etc.).
4.5 Taring (Zeroing)
The tare function allows you to zero the scale with a container on the pan, so only the weight of the contents is measured.
- Place the empty container on the weighing pan. The display will show its weight.
- Press the →0← button (often marked with 'T' or 'Tare'). The display will return to '0.0'.
- Add the material to be weighed into the container. The display will show the net weight of the material.
4.6 RS232 Interface
The RS232 port allows for data communication with external devices such as computers or printers. Consult the specific software or device manual for instructions on connecting and utilizing the RS232 interface for data logging or printing.
