The Model 2100 Indicator will display the stream velocity. (For more complete Indicator operating instructions see
the accompanying
Model 2100 Indicator Operating Instructions
.)
MAINTENANCE OF THE SENSOR WANDS
1.
Never leave the tube sections threaded together after use. Normal corrosion of the aluminum material could
"freeze" the joints and make disassembly difficult or impossible later. For best results keep the threads and the
shaft below the threads
VERY CLEAN
and well lubricated with a medium weight oil or grease. Silicone grease or
petroleum jelly will work.
2.
Always make sure the threads as well as the bore of the mating section of the tube are
completely free of all dirt
and other particles
before re-mating the sections. The fit is necessarily close at the joints so great care must be
used when assembling the sections to prevent threaded parts from seizing.
NEVER FORCE PARTS TOGETHER
!!
3.
Always replace the Thread Protectors after disassembly of the wand.
4.
Remove the Sensor from the Slider when transporting the wand to avoid damage to the Sensor and Rotor
Assembly.
5.
Remove the Complete Rotor Assembly from the Sensor when transporting to prevent damage to the propeller and
the Fiber-Optics Rotor.
CARE OF THE MODEL 2100 SENSOR
The Sensor of the
Model 2100
Current Meter is the single most important part of the instrument and great care
must be observed for its continued accurate output.
Keep the Sensor/Propeller assembly above the stream bed when taking readings and avoid rocks and other hazards when
moving from one measuring site to another. This will prevent damage to the Rotor, Rotor Shaft, Propeller and the Sensor
Body.
Never transport or store the sensor wand with the propeller rotor installed
.
Use the 1/16" hex screwdriver to loosen
the set screw and remove the entire rotor assembly when not using the Model 2100.
Do not tighten the set screw any
tighter than necessary to keep the rotor in place on the sensor. If too tight, the set screw can damage the surface of the
rotor shaft causing it in turn to damage the inside of the fiberoptic rotor when it is removed for normal maintenance and
cleaning.
Always replace the battery in the Model 2100 Indicator with a fresh one.
1.
During rough use check the propeller frequently for frayed leading edges and for cracks. Chipped or cracked
props should be replaced. Frayed leading edges can be brought back to acceptable levels of operation by
