Customizing The EtherMeter™ Through The Setup Menu
Setup commands are entered at the “CMD>” prompt. After each command is entered, it is
recommended that the technician verify the modified setting on the Setup Menu Display. For
example, to set the run-mode baud rate to 19200, type: SET BAUD 19200 <ENTER>
SETUP MODE COMMANDS:
METER SETUP SELECTIONS DEFAULTS
SET UNIT1
GAL, L, FT3, M3, UNITS
(SELF EXPLANATORY)
GAL
SET UNIT2 GAL, L, FT3, M3, UNITS GAL
SET TB1
SECOND, MINUTE, HOUR
TIMEBASE FOR FLOW RATE CALCULATIONS.
FOR EXAMPLE… IF UNIT1=GALLONS AND IF TB1=MINUTE, THEN
THE FLOW RATE WILL BE DISPLAYED AND REPORTED IN UNITS OF
GALLONS/MINUTE.
MIN
SET TB2 SECOND, MINUTE, HOUR MIN
SET EXP1
-8, -7, -6, -5,-4,-3,-2,-1,0,1,2,3,4,5,6,7,8
SPECIFIES THE PLACEMENT OF THE DECIMAL POINT FOR METER 1. ‘0’
CORRESPONDS TO NOT MOVING THE DECIMAL POINT… ‘-1’
CORRESPONDS TO MOVING THE DECIMAL POINT ONE DIGIT TO THE
LEFT… ‘+1’ CORRESPONDS TO MOVING THE DECIMAL POINT ONE DIGIT
TO THE RIGHT, ETC… NOTE THAT THIS SETTING SCALES THE TOTAL
AND FLOW AS DISPLAYED ON THE 2X16 LCD DISPLAY AND WEB PAGE.
HOWEVER, THIS SETTING DOES NOT SCALE THE REPORTED TOTALS IN
MODBUS REGISTERS 40001-40004 AND DF1 REGISTERS N7:0-3.
0
SET EXP2 -8, -7, -6, -5,-4,-3,-2,-1,0,1,2,3,4,5,6,7,8 0
SET ROLL1
-999…-5,-4,-3,-2,-1,0,1,2,3,4,5…999
DEVICE WILL COUNT METER ROLLOVERS. USER MAY PRE-LOAD THESE
REGISTERS.
0
SET ROLL2 -100…-5,-4,-3,-2,-1,0,1,2,3,4,5…100 0
SET FCALC1
DTIME (Fixed dTime), DTOTAL (Fixed dTotal)
SPECIFIES THE FLOW RATE CALCULATION METHOD:
DTIME:
• FIXED DELTA TIME (EG. 30 SECS)
• BEST FOR REGISTER WITH 8 WHEELS
• FLOW = DELTA-TOTAL / DELTA-TIME (FIXED WINDOW = 4 x DTIME).
• FLOW RATE IS RE-CALCULATED AFTER EACH SAMPLE.
(SEE SAMP1)
DTOTAL:
• FIXED DELTA TOTAL (EG. 1000 GAL)
• BEST FOR REGISTERS WITH 6 OR FEWER WHEELS
• FLOW = DTOTAL (FIXED) / DTIME
• FLOW RATE IS RE-CALCULATED WHEN THE REGISTER
REPORTS A NEW TOTAL, UNLESS TIMEOUT1 HAS ELAPSED.
DTIME
SET FCALC2 DTIME (Fixed dTime), DTOTAL (Fixed dTotal) DTIME
SET SAMP1
N (secs) (Meter 1 Sample Period)
TIME (SECS) BETWEEN METER READS
IF FLOWCALCn=DTIME, SET SAMPn TO 8-45 SECS (TYPICAL).
IF FLOWCALCn=DTOTAL, SET SAMPn TO 3-15 SECS (TYPICAL).
8
SET SAMP2 N (secs) (Meter 2 Sample Period) 8
SET TO1
N (secs) (Flow Timeout For Fixed dTotal)
IF USING FIXED DTOTAL FLOW CALC METHOD, AND METER HAS NOT
INCREASED, AND TIMEOUT HAS ELAPSED, DISPLAY AND REPORT FLOW
RATE AS ZERO.
300
SET TO2 N (secs) (Flow Timeout For Fixed dTotal) 300
SET PWR1
N (msecs) (Time to power on register)
(WITH ENCODER REGISTERS, INCREASING THIS TIME CAN SOMETIMES
HELP OVERCOME HIGH CABLE CAPACITANCE DUE TO LONG METER
CABLE RUNS.)
FOR ABB SCANCODER AND AQUAMASTER, SET PWRn TO 400 MSECS.
