1 PVD100 ‘Point Velocity Display’ Kota Samarahan Kuching, Sarawak July 2008

2 FEATURES Senses and displays velocity counts AND velocity Senses and displays velocity counts AND velocity ‘Cleans’ and ‘Filters’ signals from cat’s whisker type current meters Top Set Rod version available (CMCSp)Top Set Rod version available (CMCSp) Powered by 2 type ‘AA’ alkaline batteries Powered by 2 type ‘AA’ alkaline batteries Two modes of operation – ‘Slow’ and ‘Normal’ ‘Bluetooth’ mode option‘Bluetooth’ mode option Stores calibration equations for up to 2 fans with 3 equations per fanStores calibration equations for up to 2 fans with 3 equations per fan

3 Hardware Connections ON / OFF button Fan connection (banana type plugs) Options ‘select’ button Menu button RS232 Interface Count LED Status LED

4 LED Features ‘STATUS’ LED - Green indicates ‘magnetic head’ type meter‘STATUS’ LED - Green indicates ‘magnetic head’ type meter - Red indicates ‘cat’s whisker’ type meter - Red indicates ‘cat’s whisker’ type meter - Blue indicates ‘Bluetooth’ mode in operation - Blue indicates ‘Bluetooth’ mode in operation ‘COUNT’ LED - flashes upon each fan revolution ‘COUNT’ LED - flashes upon each fan revolution - indicates ‘Meter Dwell’ function - indicates ‘Meter Dwell’ function - indicates faults - indicates faults

5 Main Display Indicates total counts during a measurement Indicates velocity setting (N = normal : S = slow) Indicates meter contact type (M=magnetic : C = cat’s whisker) Indicates total elapsed time during a measurement M XXX 40 N XXX.XX * M XXX 40 N XXX.XX * M XXX 40 N XXX.XX * M XXX 40 N XXX.XX *

6 Main Display (cont.) Indicates current meter fault Indicates timing interval (10 sec increments from 10 to 90 secs) M XXX 40 N XXX.XX * M XXX 40 N XXX.XX *

7 Main Display – Set for ‘Counts’ M XXX 40 N XXX.XX * M = Mag Head C = Cats Whisker Contact Counts Measuring Interval in Secs 0 = Continuous N = Normal Speed S = Slow Speed Elapsed Time in Secs Blank = OK * = Fault Detected

8 Main Display – Set for ‘Velocity’ X. XX f 40 N XXX.XX * Units: f = feet/sec m= meters/sec Velocity: -in meters: X.XXX m -in feet: X.XX f Measuring Interval in Secs 0 = Continuous N = Normal Speed S = Slow Speed Elapsed Time in Seconds Blank = OK * = Fault Detected

9 Menus Select ‘Normal’ or ‘Slow’ mode Select ‘Feet’ or ‘Metres’ Select ‘Maghead’ or ‘Cat’s Whisker Select ‘Velocity’ or ‘Counts’ Select ‘Velocity’ or ‘Counts’  VELOCTY COUNTS  FEET METERS  MAGHEAD CATWSKR  NORMAL SLOW

10 Menus (cont.) Blue LED flashes every 2 seconds Press ‘Function’ then ‘Select’ to toggle between ON/OFF settings Press ‘Function’ then ‘Select’ to increment time to desired setting Press ‘Function’ then ‘Select’ to increment time to desired setting TIME  40 SEC  OFF - BT ON COM  BLUTOOTH DISCOVER  CONNECTD Illuminates once connected then jumps to main display

11 Menus (cont.) Checks ASCII data transmission Checks serial port connection to an external device Checks connectivity between the PVD100 and current meter Checks connectivity between the PVD100 and current meter Checks signal from current meter (cat’s whisker type only)  CALIBRT YES  COMTEST YES  SER PORT TEST  DWELL? YES

12 Spin Test Press ‘Select’ when fan stops spinning Connect current meter, spin fan and press ‘Select’ Press ‘Function’ button and ‘Select’ spin option Press ‘Function’ button and ‘Select’ spin option ‘Spin’ = total number of revolutions : ‘Finl’ – total elapsed time  SPIN ? YES  SPIN 0 TEST 0  SPIN 270 FINL 243

13 Fan Equations Equation number 2 Equation number 1 Fan ‘A’ Serial number details Fan ‘A’ Serial number details Equation number 3  A=S/N  1:  2:  3: ‘Hyper Terminal’ used to input fan equations

14 Sample Fan Calibration Report HYDROLOGICAL SERVICES PTY. LTD., AUSTRALIA CERTIFICATE OF CALIBRATION Date: 27/4/ Current Meter Model: xxxxxx Serial No Fan No. 1 Serial No Diameter: 125mm Pitch: 0.25m Type of Support: Method of Calibration: Average Value Equation n < 0.42 V = n m/s 0.42 < n < 3.73 V = n m/s n > 3.73 V = n m/s Starting Velocity = m/s Maximum Velocity = m/s Note: 'n' denotes the number of revolutions of the propeller per second 'V' is the water velocity in meters per second. Range Values SlopeIntercept

15 Battery Replacement 1.Open both side panels 2.Remove and discard old batteries 3.Install 2 x ‘AA’ alkaline batteries Holding ‘ON/OFF’, ‘Select’ and ‘Function’ buttons simultaneously will re-set PVD100
