The DMT132 can be connected to a loop-powered external LED display (type Nokeval 301, Vaisala order code 226476). The display provides a reading of the output measurement parameter. The display is powered by the 4 ... 20 mA current signal, so there is no need for an external power supply.
The display is delivered at its default settings. Configure the display functions and scaling according to the documentation delivered with the display.
The loop resistance of the display must be included in the loop resistance calculation for the complete current loop. See Power Supply Requirements.
For the loop resistance of the display, refer to the manufacturer’s documentation.
