• INVERS. A1 (switches output A2 inverse to A1. A1 and A2 then operate as
change-over elements with common centre grounding contact A
⊥. Only
available when status output is selected in Fct. 3.07 ”TERM. A1”.)
• INVERS. D1 (switches output D2 inverse to D1. D1 and D2 then operate as
change-over elements with common centre grounding contact D
⊥).
• EMPTY PIPE (signals that measuring tube is empty, only with option ”empty tube
detection”)
• AUTO. RNG. (automatic range change) Setting range 5 - 80 PERCENT
(= high to low range ratio, 1:20 to 1:1.25, value must be higher than that of
Fct. 1.03 L.F. CUTOFF), see Section 5.20.
• FULL SCALE, see Section 5.19.
Select flow direction (characteristic) for full-scale range
• + DIR.
• – DIR. • 2 DIR. Select with ↑ and ↓ keys.

normally open contact: XXX > YYY
0 – 150% 0 – 150% normally closed contact: XXX < YYY
hysteresis: difference between XXX and YYY.
Press ↵ key to change to numerical setting, 1st number (cursor) flashes.
Change flashing number (cursor) with keys ↑ and ↓ . Use → and ← keys to shift cursor
1 place to right or left.
Flashing numbers (cursor) can also be directly set with the 10-key keyboard.
