How to measure the parameters of the microammeter head. To do this, connect the microammeter head according to a specific scheme. Using a variable resistor, move the arrow to the right to the 100 mark. Measure the current with a multimeter. Connect another variable resistor in parallel to the device and achieve a reading of 50. Disconnect this variable resistor and measure its resistance. The measured resistance is equal to the resistance of the device frame.
