   - For 10mΩ and 100mΩ standard resistors, it is recommended to use 4-wire resistors.
   - For OPEN calibration, do not connect any resistors.

+==== Internal Resistance Calibration ====
+Enter the settings menu and select "Internal Resistance Calibration." You can input the following 15 resistance and voltage values: 0Ω, 1mΩ, 10mΩ, 100mΩ, 1Ω, 10Ω, 100Ω, 1KΩ, -60V, -10V, -1V, 1V, 10V, 60V. Calibration can also be done for individual values.
+  - Use the left and right keys to select the resistance or voltage value to calibrate, connect the corresponding standard source, and press the AUTO key to begin calibration. The screen's section will turn yellow.
+  - The calibration process will take a few seconds,so please be patient.
+  - Calibration results: Green indicates OK, Red indicates NG.
+**Notes:**
+  - Use non-inductive resistors for calibration. Do not use wound resistors.
+  - For 10mΩ and 100mΩ standard resistors, it is recommended to use PBV 4-wire resistors.
+  - Voltage calibration requires a standard DC voltage source.
+**Additional Notes:**
+  - Although this product provides an open user calibration learning mode, it has been 100% calibrated before leaving the factory, and no additional calibration is necessary for users. If calibration is required in special situations, the above method can be followed.
+  - If calibration values are inaccurate or distorted, simply restore the factory settings to return to the factory calibration values.
