The transmitter must be powered with a voltage ranging from 12 to 32 V, applied between the -V and +V terminals.The
permissible Rload resistance, equivalent to that of the instruments applied in series to the voltage generator, must be
determined as a function of the power supply voltage value and according to the load characteristic so that its value is covered
by the working area. DAT 1112 is available in 6 different versions, covering all common sensors types. For most used sensors
a single unit cover 2 sensors, allowing substantial reduction of stocks.For programming the device, see the technical sheet
" DAT 1112 Programming Instruction ". Once the device is programmed, the calibration is carried out by adjusting the zero
and the span potentiometer as follows: apply a signal corresponding to desired minimum input signal and than adjust the
zero potentiometer to get Iout = 4,00 mA. Apply a signal corresponding to desired maximum input signal and than adjust the
span potentiometer to get Iout = 20,00 mA. Repeat these operations until the needed accuracy is obtained.
