| 7 | 0/1 | TAU time constant（0: 0.8s; 1: 4.0s） |
| 8 | 0/1/2/3/4/5/6 | Measuring range(according to the table of measuring ranges) |
| 9 | -999-9999 | Transmitter offset (informative)[ Pa](1 =1 Pa）with sign |
| 10 | -999-9999 | Lower value of the measuring range (informative)[Pa](1 =1 Pa）with sign |
| 11 | -999-9999 | Upper value of the measuring range (informative)[ Pa]（1 = 1 Pa）with sign |
| 12 | 0/1 | Offset calibration (zeroing) status (0: not active; 1: in progress) |
| 13 | 0-65535 | Counter of correct frames |

Notes:
•If you input a wrong or out-of-range parameter value, the value of 0xEEEE shall be entered in the command register.
•Each time the command is called, it must be accompanied by a password (1234 decimal).
•Calling the command through individual registry entries, must be completed by entering the password.
