Note: Measure after making sure that the center of the coil and the center of
the reed switch contacts are aligned. Initially, apply soak current (100
AT) then return to zero (AT). Next, apply the current in the same
direction and measure it. The polarity of the current applied to the coil
should make the direction of the energized magnetic field to be the same
as the direction of terrestrial magnetism. (The leading end of the coil-
wire at the top should have positive polarity.)

Specifies a maximum value of transient voltage over the contacts caused by
surge current or other external factors. Below this rated value, the reed switch
operates without destruction of its contact insulation resistance.
