page 10 Operating the BP50
3.5 Immersing the capillary
3.5.1 Manual mode
For small surface ages (up to approx. 1500 ms), the measurement can be carried
out manually.
Keep your hand as steady as possible during the measurement or calibration.
Make sure that the immersion depth of the capillary does not change
significantly during the measurement or calibration.
3.5.2 Using a stand
For surface ages > 1500 ms, the BP50 should be used with a stand.
Standard arm
1. Fix the arm to a laboratory stand using a stand clamp.
2. Fit the BP50 into the opening of the arm.
3. Place the sample vessel on a laboratory sample stage underneath the BP50.
4. Immerse the capillary by raising the sample stage.
