SLC 9 - 2 MDV full memory of a direct-reading instrument currents, Instrument Description: SLC9-2MDV full memory direct reading from a low-power microprocessor load-bearing cables, instrument composition formula currents, underwater detection section. Digital LCD, ABS proof enclosure, AA alkaline batteries. LED automatic, manual backlight, buzzer audible alert, battery voltage indication. Part double sealed structure and is equipped with an underwater corrosion double zinc ring, combined rudder, the machine is easy to install, light weight and easy to carry. Can output in estuaries and oceans flow measurement and flow measurement data from the LCD digital display and RS-232 communication interface and memory, can also be connected via RS-232 communication interface with the computer timely observation, save, print data. Automatic mode can work under the conditions of automatic memory mode unattended. Therefore, this instrument can be used as an integrated component of intelligent data acquisition system. Flows from south to north is defined as 0 degrees, the fuselage and empennage go with the flow, the flow measurement is the angle between the water and the geomagnetic. Instrument can be customized measurement mode and communication format. This instrument is suitable for shallow water, estuaries and lakes. Can be used in ships, buoys and platforms. Second, the technical indicators: flow velocity measurement range of 0 ~ 360 ° 3 ~ 350cm / s Accuracy ± 4 ° ≤ ± 1.5% Resolution 2 ° 1cm / s automatic mode (3min), (15min), (30min), 60min fast Test Mode (15s), 30s, (60s) normal mode (60s), 3min measurement period (60s), 3min memory capacity 4000 set backlight time 7s Cable length 75 m cable load 50 kg DC power DC 6.0v (on 4 AA alkaline batteries) Measurement time> 100 h (fast measurement mode continuous measurement) serial interface RS-232 (600 baud, 8 characters, no parity, 1 stop bit) Working environment -10 ~ + 40 ℃, RH < 85% by weight of 7.5kg instrument outsourcing dimensions 480x320x190 (mm) Third, the use of the main points: 1. Auto Mode Auto mode is timed automatic measurement mode for timing, location, given the deep single automatic measurement. 2. Fast measurement mode fast measurement mode is automatic continuous measurement mode. Press the power button, digital LCD display "30" press Set, hearing the buzzer sound, the instrument into the fast measurement mode. If not promptly set press the reset button to reset. After hearing the buzzer sound, LED backlight automatically turns on, LCD digital display sequentially cycle twice the flow, the flow rate measurement values. Hover velocity measured value of the state and sent to memory. Fast measurement mode without setting the date and time options, usually for tank calibration, test machine and manual recording multiple sets of measurement data, access to the flow, the flow rate averages multiple sets of measurement data. 3. Normal mode normal mode to manual measurement mode for multi-point measurements. When multi-point measurement data and the user needs to set the memory layer deep relationship itself. 1) time setting, press the power button to turn digital LCD cycle after "30" shows the year 2009, 2010, ..., corresponding to the annual value of press Set. 00. 00, 01 numerical display cycle increments. 00, ..., 00︰00,01︰00, ..., when the display value and the month, day, hour, minute, followed by a relatively seasonal setting key instrument clock setting is finished LCD digital display shows the start repeating the month, day, hour, minute, ending clock standby. 2) Data Measurement Short press Set. "" Flashing into the measuring instrument state. Information ring the buzzer, LED backlight automatically turns on the measurement data memory and cycle 4 times in clock standby instrument. When measuring again need a short press Set. Measuring the instantaneous value of the flow is the end of the week, is to measure the mean flow rate cycle. 4. LCD when the fast measurement mode to measure the flow rate of the liquid crystal display for period measurement values. Start time is displayed as the measurement cycle, the clock "︰" stop flashing. "" Flashing prompt when the instrument is working properly conventional mode measurements. Data with front "︰" logo for the flow of value, no sign of velocity values, standby clock. 5. Reset setting measurement mode to convert the measurement state basis having the reset button. Under the fast measurement mode, press the reset button, the instrument re-enter the fast measurement mode, the memory of the original data is not cleared. Under normal mode press the reset button, the LCD show "30,1111" prompted whether you want to clear the memory and reset the clock? Press Set measurement data memory will be cleared, enter time setting state. Failure to set key, LCD after start time has been set into the conventional mode standby. Before the end of the measurement data memory is prohibited off the power output, power off memory data will be fully cleared. Before replacing the battery voltage output data backup battery is recommended. 6. Fast measurement data output mode measured value is displayed only when the flow velocity measuring value cycle before they can receive an output instruction. In normal mode, the measured value output clock state to accept instruction. Press the Setup button, the LCD displays "2222" indicates that the instrument has accepted the output command, followed by the RS-232 interface to boot time and measurement data transmission to the computer. Fast measuring instrument output data mode after setting key basis having to reset fast measurement mode, normal mode is automatically reset, the original measurement data continues to set the mode display and memory. The data memory allows for multiple outputs. 7. NetTerm LCD display and computer software for data output via NetTerm and display. NetTerm install the CD-ROM software, set up as follows: 1) File → Address Book → Modem Text 2) Desktop Options → Settings → Settings → Local end response, auto-sensing 3) → Options → Settings → modem baud rate → 600; Port → selected port 4) File → host joins 5) Edit → page buffer storage volume for ...... (data archiving: xxx.txt) software remaining option is the default setting. After setting the first three LCD monitors connected via a serial cable with a special computer, computer port selected to be tested. Also turn 9-pin serial interface to connect via USB, COM port number to view the computer → Device Manager → port. Click the host connection, cursor blinking into the communication status. Press the Setup button, the data output xx. , Xxx #, xxx, followed by time, flow, flow rate. If the measurement data is not displayed, please check the option settings and cables connected correctly? 8. Installation by slotting direction vertical tail fin and horizontal push underwater probe after connecting with the locking cap back. LCD digital display containing Ni-MH rechargeable battery memory, the measurement process when battery voltage is below a preset value of the red LED lights that the battery voltage, then the need to replace the power supply battery quickly and directly. Fourth, note: 1. Measurements memory data output end please turn off the monitor only instrument cable 2. Do not flawed by squeezing and pay attention to moisture and monitor the coupling portion 3. Recommended for high-quality AA alkaline batteries for a long time, remove the batteries 4 deactivated. When the instrument measurement mode switching liquid crystal displays do not connect with the computer 5. Do not use iron magnetic couplings and counterweight 6 measuring instrument. Handle with care slurry spin axis precision instrument parts do not add lubricant 7. Do instrument contains a lot of sand or dirt in water use 8. LED lights indicate battery voltage please replace the battery 9. Instrument within one year warranty on the implementation of non-invasive failure
