 In the open state of continuous saving, the naming rule of the file name is trace + machine
number + date, such as: trace-SN12345678-
 Single save, the naming rule of the file name is trace-trg + machine number + date, such as:
trace-trg-SN12345678-20210811.csv,
3.3.6 Other test results
When the user selects the scan parameters as frequency and impedance, the instrument will
automatically display some parameters of the ultrasonic device. The specific parameters are
described as follows:
Static capacitance Ct: Static capacitance value at 1kHz.
Static capacitance Dt: the capacitance loss value at 1kHz.
The minimum impedance Zmin and its corresponding frequency fs, (point m on the screen).
The maximum impedance Zmax and its corresponding frequency fp, (point M on the screen).
ΔF = fp – fs
