# Manual to Make the Calibration Update
|
|
|
|
## 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
|
|
```
|
|
|
|
## Upload the New Scale Values
|
|
|
|
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.
