10 General Setup (PATH: config/Guided Setup) continued
UV Lamp
Once flow has been established, the 5000TOCi is ready to begin taking TOC measure-
ments. If sensor activation is desired at this time, set the UV Lamp to On. Allow approxi-
mately one minute for readings to begin. Additional time (approximately 4-24 hours) may
be necessary for the readings to stabilize as the sample line rinses clean, and the TOC
sensor reaches thermal stability.
Auto Start
The 5000TOCi sensor can be configured such that the UV lamp will automatically turn on
after recovering from a power loss or fault condition. If automatic recovery is desired, set
the Auto Start option to 'ON'. Auto Start can be configured in
Configure (C), c measurement c parameter setting
It is recommended that Auto Start be set to 'ON'. The default setting is 'OFF'.
11 Disposal
When the sensor is finally removed from service, observe all local environmental
regulations for proper disposal. Please note the UV lamp supplied with the 5000TOCi
contains mercury.
