    1.00 kΩ is the default value in the firmware, it gives the best combination of precision for cost in readily available resistors, as well as being a good compromise value for everything from PT-100 to 10k thermistors, maintaining a wide range of excitation currents.
    In certain applications, for example when only 10k thermistors are being used at low temperatures, RSENSE should be increased to near the mid-range of the expected sensor resistance, however this will greatly reduce the maximum excitation current that can be used.
