Smart Chamber or LI-8250 software not recognizing LI-870
Power is supplied from the Smart Chamber or LI-8250, and assuming your con-
nection is completed correctly, the gas analyzer is always powered on when the
Smart Chamber or LI-8250 is powered on. The Smart Chamber or LI-8250 will
automatically recognize your device with no further steps needed. Simply expand
the
LI-870
drop-down in the
Connections
menu of the
Measurement Settings
page
of the Smart Chamber or LI-8250 software, select your instrument serial number,
and press
Update
.
If you open the drop-down menu and your instrument does not appear,
l
Is your power cable fully connected to both devices? Make sure the cable is fully
inserted and the threaded nut is snugly fastened.
l
Is your USB cable fully connected to both devices? Ensure that the connectors
on both sealed cables are clipped to the prongs on each device.
If your cables are fully connected but you still cannot identify your device, you can
open your device to see if power is being supplied. Next to the connection panel
inside the case, a red LED light will be blinking if power is being supplied.
