In this case, an accurate SRHHM is needed when selecting the site of the DC grounding to inhibit grounding
electrode current which can effectively avoid DC bias.
The
electrode current response of glucose shows excellent stability and reproducibility.
FNS occurs when the
electrode current stimulates the labyrinthine portion of the facial nerve, and this is not an unusual occurrence in patients implanted for otosclerosis [8, 9, 11, 16].
Plane electrode 1 is grounded via microammeter 6 destined for measurement of the total
electrode current. Narrow conductive strip 7 is attached to the plane electrode 1 and insulated by means of dielectric layer 9.
The calibration plot obtained for the modified
electrode current response against the dopamine concentration is shown in Figure 13, and it shows a linear relationship toward the DA concentration in the range of 0.0 to 90 [micro]M.
The catalytic current was estimated by the difference between the
electrode current in the presence of sulfhydryl compounds and that which is established in the blank solution.
For instance, the
electrode current is about 0~15,000A, which is converted by the current transformer into a current signal of 0~5A, and then go through the current transmitter and becomes the standard current signal of 4~20mA.
The inner layer reactions were greatly reduced at a platinum oxide coated electrode resulting in lower passivated
electrode current flow [22].
However, unlike standard GMAW equipment, STT machines give precise control of the
electrode current throughout the entire welding cycle.
