1Product Series and Parameters
| Sn# | project | unit | metric | test condition |
| 1 | input range | mA | option | this board range is -50mA~+50mA,and corresponding accelerometer range is -40g~+40g |
| 2 | Zero temperature coefficient |
nA/℃ | ≯2 | Test the data set per ℃ every 5 degrees from-40℃ to + 85℃ Test 100S, calculate the temperature coefficient of each segment, and connect the input end to 0 signal. The temperature box is stable and then insulated for 1h for testing. |
| 3 | Scale factor temperature coefficient | ppm/℃ | ≯3 | From-40℃ to + 85℃, a set of data is tested every 5 degrees, each set is tested 100S, the temperature coefficient of each segment is calculated, and the input terminal is connected to ± 1 mA DC current signal. After temperature stabilization Reinsulation for 1h for testing. |
| 4 | Zero stability | nA | ≯2 | The input end was connected to the 0mA signal, and then the output of the AD conversion board was collected for a total of 8h, after which the standard variance was calculated |
| 5 | scale factor stability | ppm | ≯3 | The input is connected to ± 1 mA signals, and then collect the AD conversion board Of the output, collect for a total of 8h, and then calculate its standard variance |
| 6 | start time | s | ≯20 | It enters a stable state 5s after starting 20S |
| 7 | degree of linearity | ppm | ≯10 | Test through the current in the input range |
