⚙️ Hardware Setup, Adjustments & FAQs

❓ Where to connect the test leads for each measurement type? cfg_01
The BLACK test lead always goes into the 'COM' input. The RED test lead goes into the 'VΩmA' input for measuring voltage, current (up to 200mA), and resistance. For currents above 200mA, use the specific '10A' input (if available and applicable to the model).
