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.
