LOOP1 and LOOP2 can output signals for any 2 of 4 different scales: ASTM, Saybolt, Platinum/Cobalt, and Haze. This
will be set at factory according to end user specifications.
To change 4-20 mA output scale, insert a jumper across the pins next to the label for the desired scale. See Fig. 3-15
Place ONE jumper in J5 (LOOP 1) and one in J7 (LOOP2) to select two scales total. The CHA does not require
recalibration after changing scales. In most cases LOOP1 will be set for haze and LOOP2 to the specified color scale.
CAUTION: Inserting more than one jumper for either LOOP or inserting the jumper across two inputs or two outputs
will result in the malfunctioning of the instrument.
