Frequently asked questions

Below are some of the most asked questions regarding troubleshooting and support

How do I check if a lamp is broken?

The lamp sends out NIR and visible light at the same time, so basically check for a light spot either on the fibre output for the probe or remove the accessory from the at-line instrument and check for a clear bright light spot.

Can I clean the white reference disk myself?

Some white reference products come sealed in Teflon or glass, these can be cleaned with a damp cloth wetted in tempered water. The white reference products with the optical white powder exposed cannot be cleaned by unauthorised personnel and the reference may be destroyed by applying water or alcohol.

Can I run the connection to the instrument over our local LAN?

In theory yes as all communication is TCP/IP based, but the analyser must have its fixed IP address and the communication takes some 3-5 Mbit bandwidth and must have priority to not corrupt data. Fare better to run the instrument on a separate LAN between the instrument and the controlling PC responsible for spectral acquisition.

What is the expected blinking sequence for the LEDs found on the instruments?

Slightly depending on the model (see details in the manual) but in general for all instruments one may observe a special sequence during start-up (first 60 sec) and when everything is running normally one of the LEDS, often the “DATA LED” will flash, indicating data communication and collection. If the instrument is stuck on one LED it may be busy doing self-diagnostics for a minute, but after that it may indicate a problem. Turn the analyser of for 2 minutes and turn it back on. If this solves the problem allow 30 minutes before using the instrument to let all Peltier Cooling in the detector system take effect again.

I forgot my password in InfraQuant, how do I reset it?

Contact Q-Interline support for help.

Is there a master password for FTSW100 config tool – I forgot it?

Yes, contact Q-Interline support for help.

InfraQuant reports Loss of intensity during the reference step.

Often one simply forgot to place the white reference on the accessory or the white reference or the window on the accessory was dirty. Clean the window and the reference disk (glass/Teflon only) and rerun the reference step. Minor losses or variations of a few % is normal. If the system is hooked to AnalyticTrust, this system will warn for any trends to worry about.

I wish to move my inline probe or cell; can I extend the fibre length?

No, the fibres used for in-line probes and cells cannot be extended due to the way they are constructed. The fibre construction uses small bundles of fibre and the loss of signal in an extension would diminish the performance significantly.
