MODEL 3000-STDX, 3000-LX,
Sensor Wand Operation and Maintenance
(See separate documents for Indicator operating instructions)
EXTENDING THE SENSOR WAND
The Sensor Wand is lengthened by loosening the hose clamps, pulling the telescoping sections apart
to the desired length, then re-tightening the clamps. A 5/16" nut-driver is supplied to operate the
clamps, however a screwdriver or coin may also be used.
A red painted groove is cut into each telescoping section indicating the maximum recommended
extension but no stop is provided and each section can pull out of the other if extended too far.
Carefully re-insert the section if separation occurs. NOTE: When shortening the wand it is important
to continually take up all the slack in the cable to prevent binding of the telescoping sections.
USE OF THE DEPTH PROBE
If the depth probe is desired the last (smallest) section of the wand must be extended to its
maximum length. The sensor must also be swiveled from the "stowed" position to the 90° "read"
position. Next slide the depth probe up through the 1/4" hole in the back of the sensor swivel and
screw the threaded end of the probe into the sliding collar. Raise or lower the depth probe using the
collar until the probe allows the sensor to rest at the desired depth from the stream bottom. To lock
the collar in position use the 5/16" hex head wrench and tighten the lock nut on the collar.
OPERATION WITH THE MODEL 3000 CURRENT METER
Connect the sensor to the indicator via the twist-lock connector. Swivel the sensor boom to the
desired angle (90° only when using the depth probe) and point the propeller into the stream flow.
The Model 3000 Indicator is now ready to compute velocity. NOTE: This is the rudimentary form of
operation of the current meter. For the complete capabilities and options of the instrument see the
accompanying MODEL 3000 INDICATOR OPERATION INSTRUCTIONS.
