TM
R/W
R=read only
R/W=read from either int or float formats, write only to integer format.
NV Value is stored in non-volatile memory. The value will still be available if the meter experiences a power loss and reset.
Format
UInt Unsigned 16-bit integer.
SInt Signed 16-bit integer.
ULong Unsigned 32-bit integer; Upper 16-bits (MSR) in lowest-numbered / first listed register (001/002 = MSR/LSR).
SLong Signed 32-bit integer; Upper 16-bits (MSR) in lowest-numbered / first listed register (001/002 = MSR/LSR).
Float 32-bit floating point; Upper 16-bits (MSR) in lowest-numbered / first listed register (257/258 = MSR/LSR). Encoding is
per IEEE standard 754 single precision.
Units Lists the physical units that a register holds.
Scale
Factor
Some Integer values must be multiplied by a constant scale factor (typically a fraction), to be read correctly. This is done to allow
integer numbers to represent fractional numbers.
Range Defines the limit of the values that a register can contain.
