ASCII String commands

'?Setf + CRC + cr' Version 2.xx read command
'!Setf + value + CRC + cr' Version 2.xx write command

Returns ASCII string 'Setf + valueSe CRC + cr'

Values are a string of digits and an optional decimal place: '10.00'
CRC=redundancy check bytes; cr=carrage return byte.

SETPOINT_RAM

DESCRIPTIO

N

SETPOINT_RAM returns the current ram memory value setpoint with read command.
The write command sets the ram memory value and makes it the active setpoint.

ASCII STRING COMMANDS

'?Setr + CRC + cr' Version 2.xx read command
'!Setr + value + CRC + cr' Version 2.xx write command

Read returns ASCII string 'Setr + valueSe CRC + cr'

Write returns ASCII string 'Sinv + valueSe CRC + cr'

Values are a string of digits and an optional decimal place: '10.00'
CRC=redundancy check bytes; cr=carrage return byte.

UNIT_INDEX

DESCRIPTION

UNIT_INDEX selects the units the meter displays. The index value is between 1 and 30
and is assigned as shown. scc/s = 1, scc/m = 2, scc/H = 3, Ncc/s = 4, Ncc/m = 5, Ncc/H =
6, SCF/s = 7, SCF/m = 8, SCF/H = 9, NM3/s = 10, NM3/m = 11, NM3/H = 12, SM3/s =
13, SM3/m = 14, SM3/H = 15, sl/s = 16, sl/m = 17, sl/H = 18, NL/s = 19, NL/m = 20,
NL/H = 21, g/s = 22, g/m = 23, g/H = 24, kg/s = 25, kg/m = 26, kg/H = 27, lb/s = 28,
lb/m = 29, lb/H = 30
