(2) Static Discharger Tip to Static Discharger Retainer.
R (a) Use a Megohmmeter 500 Mohms - 500 VDC,1 mA max to measure the resistance between the tip of the static discharger and the static discharger retainer as follows: - connect one probe to the tip of the applicable static discharger - put the other probe against the side of the applicable static discharger retainer.
R R NOTE : With one lead attached to the retainer, clip the other____ lead to a piece of WET sponge or fine wire wool (used to touch the tip of the discharger).
(b) Measure the resistance values that follow: - for type 'A', between 6 and 120 Megohms - for type 'B', between 6 and 200 Megohms.
NOTE : The resistance value for all type 'B' retainers is the____ same.
