4.2 Key Function Description
4.2.1 Function Key "M"
In measurement mode, press short to turn on and enter password setting.
In measurement mode, the main variable is zeroed in 5 seconds (i.e. PV zeroing).
In the setting mode, the short press is used to modify the enabling parameters, the modified parameters flicker, the confirmation parameters are changed again, and the modified parameters stop flickering.
4.2.2 Full key "S"
Short press in measurement mode is the function of modifying display mode.
In the measurement mode, the full point of the transmitter can be calibrated by pressing 5 seconds.
In the setting mode, one function is added for setting parameters, and one function is added for long-time continuous shifting.
4.2.3 Zero-setting key "Z"
Short press in measurement mode is the function of modifying display mode.
Five seconds in measurement mode is used to enter the zero-setting function (i.e. to calibrate the zero of the transmitter).
In the setting mode, to set the function of parameter shifting and subtracting one, long-time continuous shifting or subtracting one.
Overview of 4.2.4 Key Functions
The instrument sets and collects all parameters input and calibration data through three keys of the panel. Various optimization measures have been taken to improve the operation speed of customers.
The shift key and the increase key of the instrument have the function of variable speed.
The instrument has both shift and incremental input methods. For menus requiring a large number of modifications, the incremental method is adopted for menus requiring continuous input data.
Instrument will stop analog output in the setting state, so if the user does not operate the instrument within 60 seconds, it will automatically exit to the measuring state.
The instrument will save all the parameters set when it exits the menu normally.
4.3 Fast Function
The instrument has three fast functions: main variable zero clearing, zero active migration and full active migration, which are convenient for users to set on-site.
4.3.1 Principal Variable Clearing
Principal variable clearing is PV clearing, which is the zero of relative atmospheric pressure, not the zero of sensor range. Put the transmitter directly under atmospheric pressure and press the "M" key for more than 5 seconds, then it can enter the main variable zero-clearing function. For example, on the right, the menu area shows "P=0". Through the "S" key and "Z" key, select the operation needed, and the prompt area shows accordingly:
"NO" will not be cleared by the editor-in-chief.
"YES" for the editor-in-chief clearing zero;
"RESET" restores the zero before the zero clearing operation;
If there is no key operation within 30 seconds, the instrument will return to the measurement mode. This function is prohibited in the production process, suitable for use in the field.
4.3.2 Zero Active Migration
Active zero migration is to set the current pressure to the zero output of the transmitter, exert zero pressure on the transmitter, press the "Z" key for more than 5 seconds, the instrument will alternately display the current pressure value and zero output current value, such as the right figure, the menu area shows "LSt", through the "S" key and "Z" key to select the operation needed, lift. The indicator area is displayed accordingly:
"NO" does not perform zero active migration;
"YES" performs zero active migration;
If there is no key operation within 30 seconds, the meter will return to measurement mode. This feature is prohibited during production and is suitable for use on site.
4.3.3 Active migration at full point
The full point active migration is to set the current pressure as the full point output of the transmitter, to apply a full point pressure to the transmitter, press the "S" key for more than 5 seconds, and the meter will alternately display the current pressure value and the full point output current value., as shown in the figure on the right, The menu area displays "HSt". The "S" and "Z" keys select the actions to be performed. The prompt area is displayed accordingly:
"NO" does not perform full active migration;
"YES" performs full point active migration;
If there is no key operation within 30 seconds, the meter will return to measurement mode. This feature is prohibited during production and is suitable for use on site.

4.5 Menu description
This instrument menu is divided into "production debugging menu"; Advanced User Menu; The "Ordinary User Menu" level 3 is distinguished by the entry password of the menu at all levels.
"Production Debug Menu"
The entry password is "00066", which is used by the transmitter manufacturer. The basic parameters of the transmitter are set, and the accuracy, calibration value, and other parameters of the transmitter are determined. Therefore, the production debugging menu can not be open to ordinary users to avoid calibration data. Destruction.
"Advanced User Menu"
The entry password is "00016", which is used when performing some special settings for the transmitter on-site use requirements.
Ordinary User Menu

COE: Sensor sensitivity correction coefficient, range(0.0001 ~ 1.9999), menu prompt "GAIN"
During the use of the transmitter, if the sensitivity of the sensor changes, it can be corrected by this menu. Before the sensitivity correction of the transmitter, the zero error of the transmitter should be corrected by the primary variable zero(PV zero) function., To ensure that the linearity of the sensitivity correction is normal, the default value of this menu is "1.0000".
For example, the range of transmitter calibration is from 0.00000 to 20.000 MPa. After a period of time, the zero point becomes "0.0050 MPa" and the full point becomes "20.160 MPa". At this time, the zero point and sensitivity of the transmitter have changed. When correcting it, the zero error of the main variable should be cleared by using the zero function of the main variable. After the zero variable is cleared, the zero point of the transmitter is "0.0000 MPa" and the full point is "20.110 MPa". Then calculate the theoretical full point divided by the actual full point value to correct its sensitivity, IE 20.000 MPa/20 .110 MPa = 0.9945, and modify the sensor sensitivity correction coefficient to "0.9945" to correct the sensitivity change.
