distribution board position "x13, COND-POS".
g) Call debug screen 5. TWO (2) checks then proceed according to the TWO (2) possible scenarios after
check #2:

right, at top) for exactly one (1) minute noting its highest and lowest values. Subtract
the lowest value seen from the highest. 2 (two) or less = GOOD! MORE THAN 2 =
BAD!
CHECK #2 (CPOS): Now watch CPOS (4
exactly one (1) minute noting its highest and lowest values. Subtract the lowest
value seen from the highest. 8 (eight) or less = GOOD! MORE THAN 8 is BAD!
IF (and ONLY if) TPOS AND / OR CPOS ARE BAD:
