testing method
After the helmet is pretreated, stick two electrodes on the flat part of the helmet. The electrodes should be placed in parallel with a distance of 10mm±0.5mm. The electrodes and the helmet should be bonded with conductive glue. The resistance value of the conductive glue Should be <1KΩ; connect the measuring end of the high resistance meter to the electrode, read the resistance value displayed by the high resistance meter; then exchange the electrode to repeat the test once, and record the displayed value; The average of the two measurement readings is the actual measured surface resistance.
