PeakForce QNM Limits

These parameters work like other limits in the NanoScope software. Numbers in the NanoScope software are represented using 16 bits and thus various quantities are represented as illustrated in Figure 1.

As with other limits, setting the limit too high increases the bit noise. Setting the limit too low can result in wrapped data and inverted contrast. The limits of the following parameters can be set by the user:

• Force Limit: affects the Peak Force and Adhesion channels.
• Dissipation Limit: affects the Dissipation channel.
• DMT Modulus Limit: affects the DMT Modulus channel.
• LogDMT Modulus Limit: affects the LogDMT Modulus channel.
• LogDMT Modulus Offset: affects the LogDMT Modulus channel.
