Menu function and operation introduction for SYPM-23 Pressure Transmitter
| Menu name | Function description |
| POINT | At menu interface “POINT”( “POINT” flickers), press M button to enter its parameter setting interface, press Z button to select decimal digits. ( select range: 0, 1, 2, 3, 4 )
0: No decimal digit. 1: One decimal digit. 2: Two decimal digits 3: Three decimal digits 4: Four decimal digits After complete setting, press M button to save, then press S button return menu interface “POINT”, then press S button return measuring status. |
| UNIT | At menu interface “UNIT”, press M button to enter its parameter setting interface, press Z button to select engineering unit. ( Selectable unit: Mpa, mmH2O, PSI, Bar, mBar, Pa, Kg/cm2, Kpa, mA, %, mm, M, mH2O )
After complete setting, press M button to save, then press S button return menu interface “POINT”, then press S button return measuring status. |
| LOWER | Menu “LOWER” is used to set up the value which is corresponding to 4 mA.
At menu interface ” LOWER “, press M button to enter its parameter setting interface, at this time, the rightmost digit is flickering, press Z can select number from 0 to 9, press S button can shift cursor. When the cursor is flickering on the leftmost digit, press S, the symbol “-” flickers, press Z can select minus sign or positive sign. ( If flickering rate of “-” speeds up, it means minus sign is selected. If flickering rate of “-” is slow, it means positive sign is selected, positive sign does not display ) When the sign “-” flickers, press S, the decimal point flickers, press Z can select location of the decimal point. After complete setting, press M to save, then press S return menu interface ” LOWER “, then press S button return measuring status. |
| UPPER | Menu “UPPER” is used to set up the value which is corresponding to 20 mA.
Setting method is the same as that for Menu “LOWER”. ( The parameter of menu “UPPER has no sign bit ) |
| DAMP | Menu “DAMP” is used to set up damping time, unit is “S” (second).
Valid set range: 0 ~ 64 seconds Setting method is the same as that for Menu “LOWER”. ( The parameter of menu “DAMP” has no sign bit ) |
| LOOP FIx | Menu “LOOP Fix” is used to set up fixed output current.
At menu interface ” LOOP Fix “, press M button to enter its parameter setting interface, press Z button to select output current. ( selectable output current : 3.800mA, 4.000mA, 8.000mA, 12.000mA, 16.000mA, 20.000mA, 20.800mA ) |
| CLR ZERO | Menu “CLR ZERO” is used for calibration pressure Zero point. Operation as follow:
> Make the pressure transmitter be under the condition of zero pressure. > Power on the pressure transmitter. > At menu interface ” CLR ZERO “, press M button to enter its parameter setting interface, use Z button and S button to set value into 0.0, then press M to save. > Press S button return menu interface ” CLR ZERO “, then press S button return measuring status. |
| DENSITY | Density setting is only valid for the condition that the selected engineering unit is mm and M.
Setting method is the same as that for menu “DAMP”. ( density unit is g/cm3 ) |
| ALARM | Menu “ALARM” is used for out of range fault alarm.
At menu interface ” ALARM “, press M button to enter its parameter setting interface, press Z button to select Low limit alarm or High limit alarm. ( select range: 0, 1 ) 0: high limit alarm (20.8mA), 1: Low limit alarm (3.8mA) After complete setting, press M to save, then press S return menu interface ” LOWER “, then press S button return measuring status. |
