2-11 Installation INSTALLATION PROCEDU RE Installatio n consists o f mounting t he trans mitter and se nsor ass embly and making electrical connect ions. If mounting the transmitter directly to the sensor assembly , use the process mounting technique shown in Figure 2 -1 or Figure 2-2, on page 2-3.
Rosemount Model 444 Alphaline T emperature T ransmitters 2-12 Preliminar y Checkout 1. F or any Mod el 444 unit, first verify that the tr ansmitter is cal ibrated t o the required range. Calibration is usually perfo rmed by subs tituting an input in place of the s ensor , and this is mo st conveni ently accomplis hed prior to sensor connect ion.
