Sufficient electrolyte is provided for initial servicing of the cell. Elec-
trolyte for future service should be ordered from Teledyne. When ordering,
specify type and quantity.
Prior to servicing and installing the cell, inspect the lead electrode in
the acrylic base for signs of oxidation, indicated by a reddish-brown or
yellow discoloration. If discoloration is noted, clean the cell as directed in
section 5.5.2 before placing it in service.
WARNING:
1) Remove the four cell mounting bolts which secure the plastic
2) Pour about half the furnished electrolyte into the cell and slosh
3) Wipe the top of the cell and the O-ring with a clean, disposable
4) Carefully pour in electrolyte until it just touches the bottom edge
NOTE: The electrolyte level in the cell is critically related to its sensitivity
due to the change in the cathode surface area exposed to the
eledctrolyte.
5) Carefully place the cell under the cell mounting plate with the

of the silver screen assembly at all points. This is indicated by a
definite wicking of electrolyte onto the screen assembly at every
point along ithe bottom edge. It is essential at this point that the
bottom edge of the screen assembly be wetted at all points (as
seen by the wicking action), but not over-immersed (as large a
surface area as possible of the screen assembly must remain
above the electrolyte, while every point of the bottom edge must
be wetted). The level is correct when the bottom edge of the
sensor screen is wetted but not immersed; approximately
