After sending the DO command string and addressing the Model 4200-SCS to talk, the output data
string will be sent to the computer in the following format:
X±N.NNNNE±NN,X±N.NNNNE±NN,...X±N.NNNNE±NN
Data status
X =
Reading (mantissa and exponent)
±N.NNNN E±NN

Data format for user mode readings

For user mode operation, the TI or TV command string is used to trigger and obtain a reading.
After sending the TI or TV command string and addressing the Model 4200-SCS to talk, the output
data string will be sent to the computer in the following format:
32. The hierarchy for data status is L, V, X, C, T, N.
33. Scientific notation for the reading exponent:
E+00=10
E-03=10
E-06=10
E-09=10
