Tell me which option to use or paste any source text or context for UMA-5588 and I’ll write the guide accordingly.

This method is primarily applied in:

The transducer emits a continuous wave that sweeps from low (55 kHz) to high (88 kHz). As the frequency increases, the wavelength decreases. This sweep allows the signal to penetrate deep layers (at 55 kHz) while also resolving surface micro-flaws (at 88 kHz).

It defines the criteria for Appearance (e.g., whether a liquid is clear, turbid, or viscous) and Color (ranging from colorless to specific tints like "Pale yellow").

$$USI = \left( \fracM_retainedM_initial \right) \times 100$$
