Maintaining the vacuum gauge
The vacuum sensor should be cleaned regularly to ensure the device retains
its accuracy. Oil and other contaminants can interfere with the accuracy of
the device. Follow the instructions below to clean the sensor.
Switch off the device.
Put a few drops of cleaning alcohol into the measurement port.
Do not put any objects in the measurement port, as this will
damage the sensor.
Close the measurement port with a cap (1/4” SAE thread) and gently shake
the device.
Remove the cap and empty out the alcohol.
Air dry the sensor.
It is important to ensure that no alcohol remains in the device
and that the sensor is completely dry.
