TREND MODES (CON-0 B337 OR TREND MODULE 0 B356)
ARE AS FOLLOWS:
0 = INSTANTANEOUS VALUE. IF TREND RATE (TRR) = 2,
THEN SAMPLES AT EVERY 2ND SECOND ARE
RECORDED.
1 = AVERAGE VALUE. IF TRR = 2, THEN USE AVERAGE OF
ALL SAMPLES TAKEN FOR 2 SECONDS.
2 = MAXIMUM VALUE. IF TRR = 2, EACH SAMPLE IS TESTED
TO BE > EVERY SECOND FOR 2 SECONDS. LARGEST
IS USED IN TREND.
3 = MINIIMUM VALUE. IF TRR = 2, EACH SAMPLE IS TESTED
TO BE < EVERY SECOND FOR 2 SECONDS. SMALLEST
