SIGNAL INPUT CONNECTIONS AND CONFIGURATION PROCEDURES
DC INSTRUMENT 3 ½ DIGITS, FOR SIGNAL INPUT IN Vdc UP TO 200 Vdc, IN TWO RANGES SELECTABLE ON THE SIGNAL CONDITIONER
BY PLUG-IN JUMPERS. ALLOWS THE READING TO BE DISPLAYED IN ENGINEERING UNITS, USING THE TRIMMERS AND SELECTABLE
RANGES FOR SPAN AND OFFSET (see fig.3).
PROVIDES AN EXCITATION OUTPUT FOR TRANSDUCERS ADJUSTABLE FROM 10 TO 24 Vdc BY A TRIMMER.
CLOSE THE APPROPRIATE DECIMAL POINT JUMPER (FIG.5), CORRESPONDING TO THE
READING DESIRED. FOR A READING OF 14.50 PLACE THE JUMPER ON THE D2 POSITION.
