B. Amplifier Board with Turrets
Material:
•
Wire: 22-gauge tinned solid copper—
Fed. Spec. QQ-W-343; ASTM B33.
•
Solder: 60% tin, 40% lead (60/40)—
Fed. Spec. QQ-S-571.
•
Flux: MIL-F-14256, Type A; Fed. Spec.
QQ-S-571 Type RA.
Method:
a. Locate the three turret terminals on the component side of the
amplifier board. Remove any jumper wires between them (see
Figure 3-5 on page 3-6).
b. To elevate zero, connect a jumper wire between the middle
terminal and the terminal marked “EZ” (see Figure 3-5 on
page 3-6, Detail B).
c. Wrap the jumper wire once around each terminal and cut off any
excess.
d. Solder the jumper wire to the terminals using proper electronics
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 3-5 on page 3-6, 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 will be a dead band when you change direction of adjustment. Because
of the backlash, the simplest procedure, if the desired setting is overshot, is to
intentionally overshoot a larger amount before reversing the direction of the
adjustment.
