GFM2 with Nozzle and Extension Hose
The data logging facility records flow results and surge data on the GFM2
internal memory. Recorded data can be downloaded from the GFM2 via
USB connection for direct import into the included data viewing and
reporting software. There are three modes for data logging:
Log 1
Quick, on-screen results.
Log 2
Logs gas over a set period, taking a gas reading every 20
milliseconds.
Log 3
Logs gas at regular intervals.
To select an alternative mode, press and hold the ‘Reset’ button for three
seconds to enter the ‘Setup’ screen. Press the ‘Up’ button to enter the
logging options screen. Press the ‘Log’ button to scroll through the three
logging options. Use the ‘Up’ and ‘Down’ buttons to change the logging
time in each option. Once selected, press ‘Reset’ twice to return to the
main screen.
