CO- 10.0.46 BOTH PRE AND POST COND ARE STABLE
a) Pre Stbl Ct (pre-conductivity stability counter) starts at 90 and decreases one unit
per second if Pre Dev val remains less than 135. If not already, after no more than
two (2) minutes it should fall to 0!
b) Post Stbl Ct (post-conductivity stability counter) starts at 70 and decreases one
unit per second if Post Dev val remains less than 70. If not already, after no more
