# Understand Reference Point
The reference point is where your Moasure device measures from. By default, the measuring reference point is the sharp corner point, on the opposite face to the LED as indicated below.
If you're using your Moasure device with the Moasure STICK, you need to move the measuring reference point to the nose of the housing in order to maintain accuracy for your measurements.
To do this, follow these steps:
1. Go to the **Settings** menu (tap the cog in the bottom-right corner of the app);
2. Tap on **Measuring Options***;*
3. Turn on **Use Moasure STICK Attachment** by selecting **'Yes'**.
If you're using your Moasure device without the Moasure STICK, follow these steps:
1. Go to the **Settings** menu (tap the cog in the bottom-right corner of the app);
2. Tap on **Measuring Options***;*
3. Tap on **Use Moasure STICK Attachment** and select **'No'**.
