CONTROL OUTPUT, 4 - 20 MA
This feature, which would be used in conjunction with the “Flow Through Unit” feature (Part #50028)
provides a control output that varies with changing measured values of a continuous process. The control
output is obtained through the mini-phone jack marked “4 - 20 mA” on the rear panel of the instrument.
Low and high adjustments for setting desired actuation of the control element for other ranges are located
behind the access cover on the front of the instrument.
VI.
OPTIONAL FEATURE
Well Adapter for 16 mm cuvette measurement (Catalog No. 20115).
This feature is for use in applications where the sample size is limited, or where the turbidity of the mea-
sured value is sufficiently great that all the light is absorbed in the greater volume of the 28 mm cuvette.
(NOTE: The approximate volumes required for measurement in the two different cuvettes are 10 ml, in the
16 mm cuvette, and 25 ml in the 28 mm cuvette.)
