TRANSDUCER "B"
THIS SIGNAL CONDITIONER INPUT ALLOWS THE DISPLAY IN ENGINEERING UNITS OR PERCENTAGES, THE DIFFERENCE BETWEEN TWO
PROCESS SIGNALS OF 0-20 mA OR 4-20 mA.
SIGNAL INPUT "A" MUST CORRESPOND, THEORETICALLY TO THE HIGHER SIGNAL,IN ORDER THAT THE DISPLAY READING BE POSITIVE.
IF THE SIGNAL "B" IS HIGHER THAN "A", THE DISPLAY READING WILL BE NEGATIVE.
CLOSE THE APPROPRIATE DECIMAL POINT JUMPER (FIG.5), CORRESPONDING TO THE RANGE SELECTED.
