The test pencil is simple and reasonable in structure, wide in measuring range and high in safety, can eliminate induced electricity, and is high in accuracy of judging energizing of conductors.
Nerve being locally anesthetized with 0.5% cocaine, the pattern of muscle contraction may be changed arbitrarily by changing the frequency and amplitude of induction coil stimulation.
