TEST ======================================== Records a motor test in standalone mode. 1. Select position where to store the new test (should be an empty slot if no empty slot is available see 5. Clear Memory) 2. Select triggering port – The DAQ system will look for 5 consecutively increasing readings on this port in a circular buffer prior to start recording the test 3. Enter the test description – use the key pad and # key to confirm each symbol. Once the description is entered you should have the option #NEXT to continue 4. Enter Grain Weight in grams (all 5 digits should be entered – ex: 50 gr --> 00050) 5. Test Summary 6. The DAQ system will look for 5 consecutive readings that are 5 bits larger than the first reading on this port in order to start recording the test. In addition there is a circular buffer that keeps the last ? second before the detected start. The DAQ will give audio signalization when it starts recording – so you can avoid accidental activation and consequently losing the test information by not recording it. 7. Test results will be displayed 8.Test graph will be displayed *The time interval is 0.001 sec or 1000 records per second. The total record time is approximately 16,2 seconds. **There are three ports – Port A and Port B have selectable amplification. You can use the DIP switch to select the desired amplification (G=25, G= 50, G=125 or G=250 times). Port C has no amplification or G=1. ***Normally Port A and Port B are used to connect a load cell and Port C can be used to record the pressure or other electrical signal between 0 and 5v. ****In Test mode because of the high speed data acquisition (1000 samples per second) the DAQ system will record only the triggering Port thus only one port. ================================== 2. Display Results ==================================== Displays the test results. 1. Select test position to be displayed 2. Test results will be displayed 3.Test graph will be displayed =================================== 3. Transmit Data =================================== Transmits the memory data to the PC. 1. Select test position to transmit (see the Application Description for PC side) 2. Select port for data transmission 2.1. USB 2.1.1. Wait until connected 2.1.2. #NEXT to start transmission 2.2. RS232 (Serial COM) 2.2.1. #NEXT to start transmission ======================================== 4. Settings ==================================== Adjust the DAQ system settings. 1. Port Offset – the ports should be zeroed i.e. they should read 0 when the inputs are shorted. Sometimes there they don’t go to 0 for different reasons. In this case you should deduct this offset from each reading to have an accurate scaling. 1.1. Short Port A inputs i.e. + and – 1.2. Short Port B inputs i.e. + and – 1.3. Connect to ground Port C input 1.4. Press #NEXT to continue 1.5. The offset for each port will be displayed 1.6. Press #NEXT to write the offset values in the memory 2. Port Gain – Used to calibrate with weight the gain for each port. Calibration is necessary so the DAQ knows how to convert digital bits to grams and Newtons. 2.1. Select which port will be calibrated - Port A or Port B 2.2. Connect the mechanical stand and remove any weight – nothing should be on the stand i.e. no motors – only the stand – this is the tare weight. You should see the reading in bits. 2.3. Place the calibration weight on your stand. You should see the reading in bits. This is the gross weight. 2.4. Enter the weight placed in kilograms. If it is a single digit i.e. 5 kg enter 05 2.5. The calibration coefficient will be calculated and displayed as xx.xxx grams/bit 2.6. Press #NEXT to write the coefficient value in the memory 3. Temperature Sensor calibration 3.1. Use the default sensor settings (normally you should use this one) 3.1.1. Default coefficient is 16.38 bit/C (you should see the current temperature) 3.1.2. Press #NEXT to write the coefficient value in the memory 3.2. Custom coefficient 3.2.1. Enter the current temperature 3.2.2 Custom coefficient will be displayed as xx.xx bit/C (you should see the current temperature) 3.2.3. Press #NEXT to write the coefficient value in the memory ===================================== 5. Clear Memory ================================== Delete a single or all tests. 1. Delete Test – delete a single test 1.1. Select position to delete 1.2. Press #NEXT to continue 2. Format Memory – will erase ALL tests 2.1. Press #NEXT to continue ===================================== 6. Raw Daq ====================================== Continuously send the DAQ system readings in real time to the PC application. 1. Select port for data transmission 1.1. USB 1.1.1. Wait until connected 1.1.2. #NEXT to start transmission 1.2. RS232 (Serial COM) 1.2.1. #NEXT to start transmission *The time interval is 0.01 sec or 100 records per second. **There are three ports – Port A and Port B have selectable amplification.

Port C has no amplification or G=1. ***Normally Port A and Port B are used to connect a load cell and Port C can be used to record the pressure or other electrical signal between 0 and 5v. ****In Raw Daq mode because of the low speed data acquisition (100 samples per second) the DAQ system will transmit all three port plus temperature. ==================================== 7.
