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>

DEFAULTS
SET UNIT1
GAL, L, FT3, M3, LB, KG, AF, UNITS
(AF = ACRE-FT; FT3=CUBIC FT; M3=CUBIC METERS.
OTHERWISE SELF EXPLANATORY)
GAL
SET UNIT2
GAL, L, FT3, M3, LB, KG, AF, UNITS
GAL
SET TB1
SECOND, MINUTE, HOUR
TIMEBASE FOR FLOW RATE CALCULATIONS.
FOR EXAMPLE… IF UNITn=GALLONS AND IF TBn=MINUTE, THEN
THE FLOW RATE WILL BE DISPLAYED AND REPORTED IN UNITS OF
GALLONS/MINUTE.
EXCEPTION: WHEN UNITn=AF (ACRE-FT), FLOW RATE WILL BE
DISPLAYED AND REPORTED IN GALLONS / MINUTE,SEC,HR
MIN
SET TB2
SECOND, MINUTE, HOUR

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.

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)

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).
VALID RANGE: 1-28800
