5. Instruções de operação
5.1 Ligar/Desligar
- Pressione o Botão de energia (
) to turn the device ON. - Pressione e segure o Botão de energia for a few seconds to turn the device OFF.
5.2 Configuração de zero
Before taking any measurements, it is crucial to perform a zero setting to ensure accuracy. Disconnect all pressure hoses from the device before performing this step.
- Ensure the device is powered on and no pressure is applied to the ports.
- Pressione e segure o SEGURAR botão por aproximadamente 5 segundos.
- The display will show "----" indicating that the zero setting is complete.
