Register R0 and R1 (DISPLAY1_L and DISPLAY1_H)
Contains the display value of the instrument, codied in two registers
of 16 bits each. Possible values are from 999999 to -199999. Decimal
point posion is codied on register R2.
Example R0=FBF1 (hex) and R1=0009 (hex)
Register value = 0009 FBF1 (hex)
Reading value = 654321
Register R2 (DECIMALS1)
Contains the number of decimals of the display, codied in a single
register of 16 bits. Possible values are from 0 to 6.
Example R2=0002 (hex)
Number of decimals = 2 = 6543.21
Register R3 and R4 (MAXMEM_L and MAXMEM_H)
Contains the memory of maximum reading of the instrument, codi-
ed in two registers of 16 bits each. Possible values are from 999999
to -199999. Decimal point posion is codied on register R2.
Example - same example as in R0 and R1 but accessing to R3 and
R4.
Register R5 and R6 (MINMEM_L and MINMEM_H)
Contains the memory of minimum reading of the instrument, codi-
ed in two registers of 16 bits each. Possible values are from 999999
to -199999. Decimal point posion is codied on register R2.
Example - same example as in R0 and R1 but accessing to R5 and
R6.
Register R7 and R8 (SETPOINT1_L and SETPOINT1_H)
Contains the setpoint value of alarm 1, codied in two registers of 16
bits each. Possible values are from 999999 to -199999. Decimal point
posion is codied on register R2.
Example - same example as in R0 and R1 but accessing to R7 and
R8.
Register R9 and R10 (SETPOINT2_L and SETPOINT2_H)
Contains the setpoint value of alarm 2, codied in two registers of 16
bits each. Possible values are from 999999 to -199999. Decimal point
posion is codied on register R2.
Example - same example as in R0 and R1 but accessing to R9 and
R10.
Register R11 and R12 (SETPOINT3_L and SETPOINT3_H)
Contains the setpoint value of alarm 3, codied in two registers of 16
bits each. Possible values are from 999999 to -199999. Decimal point
posion is codied on register R2.
Example - same example as in R0 and R1 but accessing to R11 and
R12.
