"+" is for positive-side and "-" is for negative-side of Voltage or current source.
User can assign max 4 types of contact output from following selection.
(1)BREAK: Not Used (Normal Open)
(2)MAKE: Not Used (Normal Close)
INTG PULSE
：
Totalizing Pulse output
(3) FW INTG
：
One pulse for every totalizing unit of forward flow.
(4) BW INTG
：
One pulse for every totalizing unit of backward flow.
Output pulse width is selectable.
(5) ROFF: Receiving Echo Error Alarm
(contact closes under alarm condition)
(6) B.D.
：
Break Down (unit failure)
Alarm (contact closes under alarm condition)
(7) B.D.or ROFF
：
Contact closes
under alarm condition (5) or (6)
LIMIT
：
High or Low limit alarm
(8) HI-LMT
：
Contact closes when measuring value exceeds the limit
(9) LO-LMT
：
Contact closes when measuring value falls below the limit
Polarization is ignored for this limitation alarm.
DRCT
：
Direction output
(10) FW-DRCT: Contact closes
for
Forward flow.
(11) BW-DRCT
：
Contact closes
for
Backward flow.
RANGE
：
Analog Range selector output for double range output
(12) HI-RNG
：
Contact closes for high range values.
(13) LO-RNG
：
Contact closes for low range values.
