7.1.1.3 Load application
A typical load cycle is shown in Fig. 34.
1. The system must be in an unloaded condition to define
the zero force bias;
2. Reset the charge amplifiers and, if necessary, the peak
hold functions for both the reference and test system
measurement channels.
3. Apply the load to the required working point and then
back to the unloaded condition.
4. Record the peak values from the reference as well as
the test-system read-outs.
