Instrucciones de funcionamiento
1. Encendido y apagado
Presione el FUERZA button (usually marked with a circle and vertical line) to turn the device on. Press and hold the FUERZA para apagarlo.
2. Selección de unidad
Presione el COLOCAR button to cycle through available pressure units (MPa, kPa, bar, psi, kg/cm²) and temperature units (°C, °F). Select the desired units for your measurement.

3. Zeroing Function
Before taking a measurement, especially in a new environment or after a long period of storage, it is recommended to zero the gauge. With no pressure applied, press the CERO button to reset the reading to zero. This corrects any potential deviation and ensures accurate measurements.
4. Max/Min Value Recording
The gauge automatically records the maximum and minimum pressure values during operation. To view these values, press the COLOCAR button repeatedly until "MAX" or "MIN" appears on the display. To clear these recorded values and start a new recording cycle, press and hold the CERO botón mientras viewing the MAX/MIN display.
