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>

CORRESPONDS TO NOT MOVING THE DECIMAL POINT… ‘-1’
CORRESPONDS TO MOVING THE DECIMAL POINT ONE DIGIT TO THE

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 = DTOTAL / DTIME (FIXED).
• 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 30-180 SECS (TYPICAL).
IF FLOWCALCn=DTOTAL, SET SAMPn TO 3-15 SECS (TYPICAL).
30
SET SAMP2 N (secs) (Meter 2 Sample Period) 30
SET TIMEOUT1
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.
240
SET TIMEOUT2 N (secs) (Flow Timeout For Fixed dTotal) 240
SET PWR1
N (msecs) (Time to power on register)
INCREASING THIS TIME CAN SOMETIMES HELP OVERCOME
HIGH CABLE CAPACITANCE DUE TO LONG METER CABLE RUNS.
CAN USE 55 MSEC FOR NEPTUNE E-CODER REGISTERS.
FOR ADVANCED USERS ONLY.
500
SET PWR2 N (msecs) (Time to power on register) 500
SET SIMULATION
OFF, ON
• ON: ETHERMETER REPORTS METER1 REGISTER AS 12345678, AND
FLOW1 REGISTER TO -12345678. USEFUL FOR OFFLINE TESTING. NOTE:
SIMULATION MODE IS ALWAYS CLEARED AFTER REBOOT.
• OFF: ETHERMETER REPORTS ACTUAL REGISTER CONTENTS.
• WHEN SIMULATION=ON, THE SETUP MENU PROMPT IS: SIMUL>
WHEN SIMULATION=OFF, THE SETUP MENU PROMPT IS: CMD>
