Figure 1. Dynamometer accuracy

TB 9-6625-242-24

NOTE

Tap face of TI lightly with finger while zero checking and

before making a reading.

NOTE

Turn zero-adjusting screw in direction that will return pointer

to zero through least degree of travel.

e. Connect equipment as shown in figure 1.

f. Connect load cell indicator to 115 V ac power source. Energize equipment and allow

unit to warm up for 30 minutes.

g. Position controls on load cell indicator as appropriate for load cell to be utilized

with TI.

h. Exercise load cell and TI as described in (1) through (5) below:

Figure 1. Dynamometer accuracy - equipment setup.

CAUTION

Do not exceed capacity load on either TI or bad cell.

(1) Apply tension (force) slowly to load cell and TI to obtain an approximate

capacity load.

(2) Release tension on load cell and TI to obtain an approximate zero indication on

load cell indicator.

(3) Repeat (1) and (2) above two more times.

(4) Verify that TI indicates zero.
