grab the right and left electropolar
knobs respectively;

10. During to testing if the hands are too dry or too cold, or hold the right and left electro polar knobs
without much pressure, the testing result may not occur due to the poor contact; at the same time,
incorrect testing posture will also affect the accuracy of the testing result. The correct testing
posture shall as follows:
*
Stand up with feet slightly separated
*
Both hands hold the left and right electro polar knobs respectively with some strength.
