Key Features and Functions

• High Accuracy: Measures areas with a high degree of precision, often within \(\pm0.2\%\), suitable for engineering and mapping.
• Digital Display & Output: Provides instantaneous, clear digital readings of areas, perimeters, and lengths.
• Unit Conversion: Allows quick conversion of measured values between various units (e.g., \(cm^{2}\), \(in^{2}\), \(m^{2}\), \(km^{2}\)) and scales.
• Cumulative Measurements: Features functions to sum multiple measurements (cumulative/average), which is ideal for calculating large total areas from small segments.
• Operating Mechanism: Utilizes a tracing arm and roller wheel to record movement. When the user traces the boundary of a drawing, the encoder records the wheel's rotation—excluding slips parallel to the axis—to compute the surface area.
