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:

pip install -r .\requirements.txt

Upload the New Scale Values

Use the script:

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.
