8. Release the HOLD TO OPERATE button and
allow the lever to return to the center position.

unclamping) five times.
10. Connect load cell assembly to the clamp force
and temperature indicator and turn on display.
Test
11. Clamp the plunger to the body.
12. Record the reading on the clamp force and
temperature indicator after 2 seconds.
13. Unclamp the plunger from the body.
14. Repeat steps 1, 2, and 3 three times. Each
reading must be 380 lb. ± 10 lb. force.
15. To raise or lower reading:
a. Remove the right side cover on the stand.
b. Turn the regulator adjustment clockwise to
raise the force, counterclockwise to lower
the force.
NOTE: Calibrators manufactured after
November 1984 have a knob adjustment as
shown in the photo. Loosen the locknut
behind the knob before turning. Retighten
the locknut after turning.
Older calibrators have a screw adjustment.
c. After each adjustment, repeat the clamping
operation (steps 1, 2, and 3) to see the
results of adjustment.
NOTE: After each clamping operation,
the clamping force may tend to drop
slowly. A 5 lb. drop in 30 seconds is
normal. If the drop is greater, replace
the discharge head seal and retest.
16. If necessary, adjust the clamp monitor gauge to
be in the middle of the green area of the dial
when the clamping force is 380 lb.
NOTE: If your clamp monitor gauge has a 0
to 160 psi dial, adjust the needle so it reads
100 psi when the clamp force is 380 lb.
Support the needle with thumb and finger
near its center so it will not break.
