3.9.1 < Auto Reserve >: Setting the Dynamic Reserve Automatically
Press the < Auto Reserve > button, the system will automatically change the settings of <Reserve> according to the
current signal. The principle is to select the minimum dynamic reserve of the current measurement signal.
3.9.2 < Auto Gain >: Setting the Sensitivity Automatically
Press the < Auto Gain> button, the system will automatically change the setting of <Sensitivity> according to the current
R. The principle is that the system should choose an appropriate <Sensitivity> but no more than the maximum sensitivity.
The < Auto Gain > function in SE1022D needs some response time (generally less than 5s). If the current R fluctuates a
lot, the setting for < Auto Gain > might be fail. In this case, users should switch current menu to the [GAIN/TC]
submenu and set the R manually.
3.9.3 < Auto Phase >: Setting Phase Shift Automatically
Press the < Auto Phase > button and the system will adjust the phase shift of the reference signal to make the phase of
the input signal 0. This < Auto Phase> function needs some response time (generally less than 10s). If the current
θ
fluctuates a lot, the setting for < Auto Phase > might be fail. In this case, users should switch the current menu to
[REF/PHASE] submenu and set
θ
manually.
3.9.4 < Auto Scale >: Setting Scale Automatically
Press the <Auto Scale> button and the system will adjust the scale according to R to make the displayed value large
enough within the range. This < Auto Scale > function only has effect on display. The input and output will not be
