open circuit correction for the following 49 fixed frequency points. In addition to the
following 49 frequencies, the instrument will use the interpolation method to calculate the
data of open circuit correction for different measurement range according to the data. The
49 fixed frequency points are shown below.
10Hz 100Hz 1KHz 10KHz 100KHz 1MHz
20Hz 120Hz 1.2KHz 12KHz 120KHz
25Hz 150Hz 1.5KHz 15KHz 150KHz
30Hz 200Hz 2KHz 20KHz 200KHz
40Hz 250Hz 2.5KHz 25KHz 250KHz
50Hz 300Hz 3KHz 30KHz 300KHz
60Hz 400Hz 4KHz 40KHz 400KHz
80Hz 500Hz 5KHz 50KHz 500KHz
600Hz 6KHz 60KHz 600KHz
800Hz 8KHz 80KHz 800KHz
Second: ET35 only sets the open circuit correction for the currently set frequency.
The steps of open circuit correction based on all frequency points:
1. Press the [Meas Setup] key.
2. Press the [Correction] function key.
3. Use the arrow key to select "Open", and press the [Enter] key.
4. Connect the test terminal and the test fixture without connecting to any DUT.
5. Press the [Open] function key measure, and ET35 starts to measure the
admittance of the open circuit at the 48 fixed frequency points.

When measuring, the screen displays the progress bar of open circuit
measurement, and the system message area shows correcting....

After the measurement, the progress bar shows the unit of hours, and the
system message area will show that the correction is successful.

When measuring, the "Cancel" function key is displayed. Press to cancel the
open circuit correction.
6. Press the [On] function key to initiate the open circuit correction in the continuous
measurement.
Function keys: on, off and Meas Open
