Thanks a lot, Andrea and Janne. In the ramp mode, when I lowered the feedback setpoint to below 0.2 V (to minimize any potential force between tip and surface), and tried to ramp again, the ramp size is automatically changed to 0 nm. And the value cannot be changed back or any other number until the feedback setpoint is increased. I thought that in

Hi, All, Could anyone check if my imagination of tip movement during ramp in contact mode in liquid is correct or not? Could you correct any mistakes? 1. Once engaged, the tip is on the surface with a deflection that corresponds to the setpoint in the feedback panel. 2. Once shift to ramp mode from scan mode, the tip is still on the surface and maintained

Dear Dietmar, Thanks a lot. Your information including those in the link is very helpful. Later, when I paid more attention on getting a linear force curve, the values actually did not vary too much. They were within 5% variation. So, I will use the value obtained under similar conditions used for actual force measurements. Thanks again, Shiyue

Hi, All, I calculated deflection sensitivity using two force curves from the same probe under the same conditions except for the trigger threshold. One force curve was obtained with a trigger threshold of 0.1 v, the other was obtained at 1 v. The deflection sensitivity data were different. The latter one should be more accurate. However, when I actually

Hi, Ang, Thanks a lot. I will contact you. Shiyue

HI ALL, Can any of you give me the following information? 1. Are the ramp modes under tapping mode, contact mode, and peakforce tapping mode the same? For example, when the tip is engaged under tapping mode experimental set up and later shift to ramp mode, is the tip still vibrating? 2. I saw words Sripting Interface, Strip Chart and Force Clamping
