Rosemount 1153 Series B
Flux: Mil F 14256, Type A, Fed Spec QQ-S-571 Type RA.
B1. Method (Output Code P with Switch)
Locate the three-position slide switch on the component side of the
amplifier board (see Figure 3-3). Move the switch position to “elevate
zero”, plug the amplifier board back in, and complete the zero
adjustment.
To suppress zero, follow the same procedure, except move the switch
position to “suppress zero” (see Figure 3-3).

Suppression Switch, “P” Output
B2. Method (Output Code R and Output Code P Amplifier Board
with Turrets)
a. Locate the three turrets terminal on the component side of the
amplifier board. Remove any jumper wires between them
(Figure 3-4).
b. To elevate zero, connect a jumper wire between the middle
terminal and the terminal marked “EZ” (Figure 3-4 Detail B).
c. Wrap the jumper wire once around each terminal and cut off the
excess.
d. Solder the jumper wire to the terminals using proper electronic
soldering techniques. Clean solder joints thoroughly with isopropyl
alcohol.
e. Plug the amplifier board back in and complete the zero adjustment.
To suppress zero, follow the same procedure, except connect the
jumper wire between the middle terminal and the terminal marked
“SZ” (see Figure 3-4 Detail C).
6.
Recheck full scale and zero and fine tune if necessary.
NOTE
There is some mechanical backlash in the zero and span adjustments, so
there is a dead band when the direction of adjustment is changed. To
compensate for the backlash, the simplest procedure, if the desired setting is
overshot, is purposely overshooting a larger amount before reversing the
direction of the adjustment.
