Boreal Laser Inc. GasFinderFCr Operation Manual — Data I/O July 17th 2017
$GFDBG
Periodically, strings containing diagnostic data ( $GFDBG ) are transmitted giving internal
details of the GasFinder operation.
The
$GFDBG string is output whenever the system performs a calibration check.
Date and Time fi elds
When data is viewed using GasViewOP , the data is a true representation of the raw data from
the GasFinderFCr and the $GFDTA and $GFDBG strings have a date and time stamp. The
time in the $GFDTA string is taken from the GasFinderFCr internal clock.
When data is downloaded using GasViewOP , the fi le extension is .gvl. The date and time
fi elds are taken from the computer running the GasViewOP program. These PC generated
date and time fi elds are inserted into the data in every $GFXXX string and will appear in the
log fi le.
When data is viewed using HyperTerminal, the extension is .txt and the data is a true
representation of the raw data from the
GasFinderFCr and the $GFDBG strings do not have
a date and time fi eld. The time in the $GFDTA string is taken from the GasFinderFCr internal
clock.
4-20mA Option
Note that the 4-20mA output is taken from the pins in the DB15 output connector. The 4-20mA
output is confi gured using the
GasFinderFCr keypad. Details are given on page 4.6.
