7.10 Simulation tab
When using the Simulation mode of the SQM-LU, make sure that nothing else interrupts the sequence of readings such
as external programs reading from the SQM-LU, or settings of Interval reporting inside the SQM-LU.
7.10.1 Simulation from file
The “From file” button sends csv data from
simin.csv
(in the log file directory) to the SQM-LU in simulation mode and
puts the output into
simout.csv
. The format of the csv is shown in Table 7.2:

The resultant output records will be shown on the screen and saved in
simout.csv
(in the log file directory) in the
form of simulated result shown in section 8.7 as in the example shown in Listing 7.2:
