ONFIGURATION
The transmitter shows the status and the measure on the dot matrix LCD (
). The span
is from -99999 to 999999.
The input signal to the transmitter can be related to the output signal in the following ways:
Direct mode
= 4÷20mA output
Reverse mode
= 20÷4mA output
The direct mode is obtained by setting the lower range point with the lowest value of the range
(e.g. 0.1 bar) and by setting the upper range point with the highest value (e.g. 0.5 bar). The
reverse mode is obtained by setting the lower range point with the highest value of the range
(e.g. 0.5 bar) and by setting the upper range point with the lowest value (e.g. 0.1 bar).
To display the temperature values of the sensor push the following key during transmitter
operation:
= electronic board temperature.
The unit of measure (°C) is defined in the entry TEMP UNIT in the keyboard menu (
