4. The use of the sample interval is for evaluating proper behavior of the system while the USB is connected Because in that case the sample interval is valid and the user can observe the value s obtained from the sensor in real time In this case the user can evaluate these values every 5 seconds 4 2 SDI 12 The ML 2012 13 is provided with an SDI 12 port This port is connected to port 2 and is shared with the normal RS232 operation This means that the user has to select whether he wants to use RS232 or SDI 12 When SDI 12 is selected it acts like a SDI 12 recorder and its specific SDI 12 commands are embedded in the driver of the input sensor So the user can easily select his sensor and specify its SDI 12 adress For more information see the description of you SDI 12 sensor 4 2 1 SDI 12 Hardware The SDI 12 standard is a very commonly used interface standard in the USA In Europe it is rarely used The signal levels are quite different from those of RS232 and RS485 So you cannot connect a SDI 12 sensor to a RS232 or RS485 port it won t work The use of convertors between RS232 485 and SDI 12 is discouraged because of the high pricing of the convertors and the bad performance see note 4 2 2 SDI 12 Wiring The SDI 12 electrical interface uses the SDI 12 bus to transmit serial data between SDI 12 data recorders and sensors The SDI 12 bus is the cable that connects multiple SDI 12 devices This is a cable with three conductors
5. sample interval is no problem for the battery life because the sensor will sleep until its data logging interval is reached So don t be modest with the sample interval It gives you great comfort Set the parameter name Set both minimum option 6 and maximum option 7 values of your sensor at 4mA and at 20mA If you don t know those values you could determine the scaling by measuring two calibration points option 8 Those calibration points don t have to be at the sensors absolute minimum and maximum but just two different points within the range of the sensor e g a measurement at 1m water level and a measurement at 2m water level while the sensors range is 0 10m 6 If necessary option 9 can be used to perform an offset correction by measuring a single calibration point 7 Save and Exit Qus Your screen will look similar to the one underneath Analog sensor CO Exit 2121 Name gt gt Upperstream 21 Sensor power switch gt gt Enabled Warm up time 00 00 01 3 Sample interval gt gt Normal 00 00 105 Alarm Not Used C41 Port mode gt gt 4 20 mA 517 Parameter gt gt Water level Cb Parameter value at 4mA gt gt Om L 1 Parameter value at 2OmA gt gt 10 m 817 Determine linear conversion function 2 calibration points 41 Determine linear offset only l calibration point CRI Remove gt Manufacturers of low power instruments page 12 USER MANUAL TYPE ML 2012 13 Now we add the CT2X to th

9. The data logger uses a so called interrupt input to make this possible To connect a rain gauge use this interrupt input and connect the other site of the rain gauge to the 3V6 output Note The digital input offers the most energy friendly measurements available This is because the data logger is allowed to sleep most of the time and only capture the events of the digital interrupt e g the tipping bucket of a rain gauge In the situation where only one digital sensor is used the battery is probably going to last much longer than any other measurement For safety reasons a user can include some internal measurements in the configuration to allow monitoring of the performance of the system Example configuration Rain Measurement Here an example is shown for a tipping Bucket Rain Gauge and how to set it up in the data logger The Rain gauge should be connected to the Digital input Underneath the menu for this input is shown Digital Pulse Sensor COI Exit C1 Name Digital Pulse 2 Sample interval Normal O00 00 105 Alarm Not used 31 Port mode Internal Pull Down C47 Pulses per unit 5 5 Register mode Pulse low frequency LJ Register value 1 Pulses 71 Register reset Disabled 81 Counter unit Counter 31 Quantity unit Not used Mean Rate unit h Not used CBI Max Rate unit h Not used CCI Min Rate unit h Not used CRI Remove gt First change the name Digital Pulse into a more comprehens
