When pressing the main menu button and selecting the LCR measurement function, it is used to enter the component measurement display page. The main function menu for capacitance, resistance, inductance, and impedance measurement is the start button. The function pages in this section include (use the "soft key" to select the following page functions, the same below):<Measurement Display><File Number Display><File Count Display><List Scan Display>

[SETUP] Function key This key is used to enter the various settings screens for component testing. The functional pages in this section include:<Component Test Settings><User Calibration>Limit Settings>List Settings>

The [SYSTEM] key is used to enter the system settings homepage. The main focus is on the start button of the system settings and file list function menu. The functional pages in this section are: System Settings>Network Settings>Default Settings>System Operations>

After pressing the [SETUP] key, the<Measurement Page>will be displayed. Use the cursor keys ([←] [→] [↑] [↓]) to move the cursor to the desired setting position. For example: "Function: R-X", then press the software build to change "Function: R-X" to "Function: Cp-D".

Press the cursor key [↓] again to bring the cursor to "Frequency: 1.00000KHz". To change the frequency value, press the number key group, select it, and then press the "ENTER" key to complete the test frequency setting, or use the soft key to complete the frequency addition and subtraction setting. The same method can be used to set other parameters. When a numeric key is pressed, the soft key area will display the available unit soft keys. You can press the unit soft key or the [ENTER] key to end data input. When using the [ENTER] key to end data input, the data unit is the default unit for the corresponding field parameter: Hz, V, or A. For example, the default unit for testing frequency is Hz. After setting the value, press the "MEAS" key to enter the measurement display page.

After connecting the testing fixtures related to user calibration operations, the "User Calibration" adjustment should be performed by pressing the menu key [SETUP], pressing the soft key "User Calibration", and entering the<User Calibration>page.
