6.4 Viewing Stored Values (MAX/MIN/LAST)

The tachometer automatically stores the maximum, minimum, and last measured values. To view these:

• Después de tomar una medición, presione el botón MIEMBRO botón.
• Cada pulsación del MIEMBRO button will cycle through the MAX, MIN, and LAST recorded values.
• The display will indicate which value is currently shown (e.g., "MAX", "MIN", "LAST").

7. Mantenimiento

Proper maintenance ensures the longevity and accuracy of your tachometer.

• Limpieza: Limpie el dispositivo con un paño suave y seco. No utilice limpiadores abrasivos ni disolventes.
• Almacenamiento: When not in use for extended periods, remove the batteries to prevent leakage. Store the tachometer and its accessories in the provided carrying bag in a cool, dry place, away from direct sunlight and extreme temperatures.
