In addition to the above constants, when more than one bit of the register is set, statusByte equals
the sum of their decimal weights. For example, if 129 is returned, bits B0 and B7 are set (1 + 128).

Example
statusByte = status.condition
print(statusByte)
Returns statusByte.
Sample output:
1.29000e+02
Converting this output (129) to its binary equivalent yields 1000
0001
Therefore, this output indicates that the set bits of the status
byte condition register are presently B0 (MSS) and B7 (OSB).

status.measurement.*
These attributes contain the measurement event register set.

Usage
measurementRegister = status.measurement.condition
measurementRegister = status.measurement.enable
measurementRegister = status.measurement.event
measurementRegister = status.measurement.ntr
measurementRegister = status.measurement.ptr
status.measurement.enable = measurementRegister
status.measurement.ntr = measurementRegister
status.measurement.ptr = measurementRegister
measurementRegister
The status of the measurement event register; a zero (0) indicates no bits
set (also send 0 to clear all bits);the only valid value other than 0 is 8
