mecair DPS - 4-20 mA Full Scale Setting; 4 mA Calibration; 20 mA Calibration; Zero Pressure Sensor Setting

6
4-20 mA Full Scale Value from 1 to 10 that allows to select the maximum pressure value
corresponding to 20 mA
Press “Enter” [ 2 ] to display the current value
By pressing either “+” [ 3 ] or “-“ [ 4 ] the parameter value is either increased or
decreased (an extended pressure increases the parameter switch speed)
Press “Enter” [ 2 ] to go back to the parameter selection menu after changing the
parameter value itself.
Press “Esc” [ 5 ] to go back to the pressure value display
4 mA adjustment 4 mA calibration
Press “Enter” [ 2 ] to display the current value of the adjusting datum, the 4-20
mA output emits a signal corresponding to 4 mA.
By pressing either “+” [ 3 ] or “-“ [ 4 ] the parameter value is either increased or
decreased and therefore the output value is changed; adjust till the displayed
value on the external instrument indicates the correct value 4 mA
Press “Enter” [ 2 ] to go back to the parameter selection menu after changing the
parameter value itself.
Press “Esc” [ 5 ] to go back to the pressure value display
20 mA adjustment 20 mA calibration
Press “Enter” [ 2 ] to display the current value of the adjusting datum, the 4-20
mA output emits a signal corresponding to 20 mA.
By pressing either “+” [ 3 ] or “-“ [ 4 ] the parameter value is either increased or
decreased and therefore the output value is changed; adjust till the displayed
value on the external instrument indicates the correct value 20 mA
Press “Enter” [ 2 ] to go back to the parameter selection menu after changing the
parameter value itself.
Press “Esc” [ 5 ] to go back to the pressure value display
Zero pressure Sensor Zero setting
Disconnect the hoses from the filtering taps before carrying out the Zero setting.
Press “Enter” [ 2 ] to display the current pressure value
By pressing “+” [ 3 ] the sensor is set to Zero and the Zero value is saved
Press “Enter” [ 2 to go back to the parameter selection menu after changing the
parameter value itself.
Press “Esc” [ 5 ] to go back to the pressure value display
Connect the hoses to the filtering taps
LCD Contrast To ad just the display contrast (0-63)
Press “Enter” [ 2 ] to display the current value of the parameter that adjusts the
display contrast (0-63)
By pressing either “+” [ 3 ] or “-“ [ 4 ] the parameter value is either increased or
decreased and the adjustment effects are visible on the display
Press “Enter” [ 2 to go back to the parameter selection menu after changing the
parameter value itself.
Press “Esc” [ 5 ] to go back to the pressure value display
Hour counter xxxxx Displays the operating hours (Max 99.999; cannot be modified)
Press “Esc” [ 5 ] to go back to the pressure value display
