11. To insure that the meter is functioning, turn power on (make sure no water or water pressure
is present).
12. Watch the meter face and slowly withdraw the sensor away from the holder.
13. At the meter reading where the trip point has been factory set, you should hear the relay
actuate.
14. If the relay does not actuate, you will need to make an adjustment. Adjusting the edge thumb
wheel with your hand.
15. This trip point is where a warning device like an audible alarm will be triggered.
16. To lower the meter reading, slowly withdraw the sensor head from the module assembly
while observing the meter and listening for the relay click. By inserting and removing the
sensor head a little at a time, the meter will move over the trip point area. Adjust the thumb
wheel to the desired setting
17. Now, tighten the sensor probe to the module.
18. The meter reading should be near or above full-scale reading. It may take one to two
minutes for the meter to read full scale.
After 100-hour burn-in, the UV display will need to be re-set to Full-Scale (100%). This is done during
nominal operating and water quality conditions. This UV reading is not NIST calibrated to absolute mW/cm2
intensity. It cannot be used directly in calculating dosages. It is simply a relative % of its nominal specified
operating performance. Initial setup is obviously 100 % of nominal performance, since everything is brand
new. Subsequently, any decline in UV Relative % Intensity is likely any combination of:
•fouling quartz sleeves
•fouling UV probe face
•lamp aging
•water quality (% UV Transmission)
•UV detector aging
•eroding electrical connections.
A low UV Relative % Intensity Threshold setting may optionally* be used to activate a Common Alarm.
