Button Function 1. Without pressure, press the button for 5s for zero clearing, it outputs 4mA DC.
2. If the transmitter is excited while pressing the button, it enters calibration mode, the output can be calibrated by LED indication. Please see below chart for functions.| Button Operation | Phenomenon | Function |
| Excite power supply after pressing button | LED light on | Enter calibration mode |
| Pressurize to lower limit of pressure | LED flash 2 times | Zero calibration finished, low current calibration finished |
| Pressurize to upper limit of pressure | LED flash 3 times | FS calibration finished, middle current calibration finished |
| Pressurize to upper limit of pressure | LED flash 4 times | Calibration coefficient storage finished, high current calibration finished
