+# Manual to Make the Calibration Update
 
-For installing the requirements use:
+## Changing the Range from 10 µA to 100 µA
 
-```
+This guide describes the required hardware and software changes to update the calibration range from **10 µA** to **100 µA**.
+
+---
+
+# 1. Hardware Update
+
+Replace the resistor values on the PCB from **2 kΩ** to **200 Ω**.
+
+### New Resistor Part Number
+
+- **RNCF0603TKY200R**
+
+### Resistors to Replace
+
+The following resistors must be changed:
+
+- R10
+- R28
+- R46
+- R64
+- R82
+- R100
+- R118
+- R136
+
+---
+
+# 2. Software Update
+
+After completing the hardware modification, update the device configuration using the provided Python script.
+
+## Install Requirements
+
+Run the following command to install all required Python packages:
+
+```bash
 pip install -r .\requirements.txt
 ```
 
-Use the `MTB_UploadNewScale.py` script to upload the new scale values.
+## Upload the New Scale Values
 
-1. Enter your serial number
-2. depending on you country, enter the meanCount (240 for europe and 250 for the usa)
-3. It uploads the configuration
+Use the script:
+
+```bash
+MTB_UploadNewScale.py
+```
+
+### Procedure
+
+1. Enter the device serial number.
+2. Depending on your country, enter the correct meanCount value:
+   - 240 for Europe
+   - 250 for the USA
+3. The script uploads the new configuration automatically.
+
+## Calibration Update Complete
+
+After the upload finishes successfully, the device is configured for the new 100 µA range.
