It seems the problem is you ramped IV but you triggered force, and you used absolute trigger. You may change them and check again. Another simple way to control your z piezo position is to set z start manually. Ang Li

Single approach is like engage and ramp, single ramp is ramp only, so I guess your impression was reversed. The ramp rate and approach velocity is correlated, based on your ramp size setting, you change one, the other changes spontaneously. Ang Li

Unfortunately I don't think there is. We will send a request to our software development department to implement in next available release. Thanks! Ang Li

Can you send me your contact information and I will send you a brief instruction. My email is Ang.li@bruker-nano.com. Ang Li

Hi, I guess you have some misunderstanding in following the relative method. You should have calibrated deflection senstivity and spring contant and then adjusted the tip radius to get the specified modulus value on the standard sample. Don't worry about getting an odd number of tip radius, say 100nm or 1nm, using relative method, tip radius is

The example shown in the manual taken with the range set to 1-100kHz, and yours is 5-2000kHz, data density is different. if you would like to have a smoother curve, you can trying changing bin width and median filter width. Ang Li

Hi, you may try increasing your setpoint. Have you got reasonable topography image before ramp? Ang Li

Hi, Can you try negative 'delta' for setpoint feedback? Besides, if your creep test is less than 32 seconds, you can use HSDC to capture the force curves, easier to set surface delay in force ramp mode. Ang Li

I guess you can try increasing the ramp size. Ang Li

You just need to update the tip half angle in the software before you can apply sneddon model. Ang Li
