Sweep Points. ■Open Correction: the correction of stray admittance in more than 1kΩ as resistance ■Sweep mode: Single: Graph of G and B against Sweep frequency and G-B graph displays. Repeat: Graph of Fs against time displays. ■Repeat Interval: The interval repeat sweep in Repeat of Sweep mode. ●Advanced Settings ■Auto: The default value according to Sweep Start Freq. ■Waiting Time: The waiting time until the drive Freq. becomes stable. ■Phase Shift Corr.: The correction of the delayed current phase due to thevoltage in high Freq. ■Sampling Cycles: The sample cycles for the increased noise in high Freq. ●User settings ■ User Settings: The selectable 5 batch setting of Measurement Conditions and Advanced Settings Measurement and graph display It displays Graph of G and B against Sweep frequency and G-B graph or Graph of Fs against time and Measurement Results and Approximation Results. These results mean the equivalent circuit of resonator and the admittance circle diagram. Its excel data are useful for the customer’s original applications.
