Assistance 

TIA's customers and partners working to validate our hardware for 

specific applications, where the application engineering and 
development work is undertaken at customer locations, may use this 
document as a guide. This document is a suggested procedure only and 
is based on an understanding of the hardware operational requirements, 
not detailed knowledge of the specific application parameters and 
variables.  These suggested experiments are the first sequence only, 
additional experiments will probably be required to fully characterize 
the process fluorescence. 

A-1.1  Series 1 - Initializing the Unit and 

Determination of the Probe/Analyzer Signal 
Level  

The following initialization sequence assumes that application 

engineering is being performed in a laboratory setting. The hardware 
installation is assumed to be minimal (unit is placed on a bench).  

1)

 

Mount the fluorescence probe on a lab stand.  The probe 
comes from TIA with a black PVC cap over the sensing tip. 
Leave this cap in place. Initialization of the unit will occur 
with the cap in place. The initialization sequence below will 
result in determination of the probe/analyzer residual 
fluorescence level.  

2)

 

Connect the electrical, 4-20 mA output and fiber optic 
cables as described in Section 4. 

3)

 

Power-up the Fluorometer. 

4)

 

Allow the system to operate a minimum of one hour before 
completing the rest of the initialization instructions.  

5)

 

After lamp warm-up and stabilization, the REF DET LED 
should have a steady green output. The MSR DET LED 
should have either a solid green or flashing green output.
