Powering the analyzer and making measurements
After connecting the power cable, you should power on your Smart Chamber or
LI-8250 and launch the user interface software. Power to the LI-870 is supplied dir-
ectly from the Smart Chamber or LI-8250.
Identifying the LI-870 serial number
In the
Settings
page of the Smart Chamber or LI-8250 interface, you will need to
connect to your LI-870 using the serial number. The label is on the bottom of the
case.
Warm up time
The LI-870 will boot up as soon as power is supplied from the chamber. The
optical bench should be allowed to warm up prior to taking measurements. The LI-
870 optical bench is temperature- and pressure-controlled, so a sudden influx of
ambient air into an optical bench that has not been allowed to warm up and sta-
bilize will likely produce noisy data. For this reason, it is critical that your analyzer
is allowed to warm up prior to taking measurements. In most cases, 10 to 15
minutes of warm up time will allow the optical bench to stabilize, but warmup
time depends largely on ambient temperature.
