-forOpenChannelFlow
1.Beforestartingthecalibrationdetermine:
a) MAXRANGE =____________________
(Maximumrange=distancefromtheSensorto
Zerolevelpoint)
b) MAXLEVEL =____________________
(Maximumlevelofflowthroughflumeorweir)
c) MINRANGE =__________________
(DistancefromsensortoMaxLevel)
Minimumrange=MAXRANGE-MAXLEVEL
(mustbeatleast8"/20.3cmdependingonsensor
model).
2.Checkthemaximumrangewiththesensorinstalledby:
a) Use Æ togetto UNITS/MODEthen È togetto
Range,then S
tore? Yes
(NOTE:flowmustbeatzeroflow)
or
b) Carefullymeasuredistancefromsensortozero
levelwithtapemeasure.
NOTE:TheSLT32willnotdetecttargetsbeyonduser
entered MaxRg.
