Introduction

All OMEGA force gauges are
easily mounted any of the test
stands. The combination of
gauge and stand will create a
high-precision, compact load
tester for a wide range of
applications. In addition, any
model can be converted to
any other model by following
procedures in this manual.

Model DFG-TS-C, the factory
standard configuration, is for
a compression application.
When you pull the lever arm
down and toward you, the
gauge will also come down
and compress.

Model DFG-TS-T is config­ured for tension. When you
pull the lever arm down and
toward you, the gauge will
move up and create tension.

Mounting the Gauge

1. Mount digital gauges to the stand using the
screws supplied with the stand. (FIG. 2)
When mounting mechanical gauges to the
stand, hold the gauge firmly and unscrew the
4 screws in back, making sure the case does
not separate. Hold gauge up to the AP-002
adapter plate (supplied), align plate and gauge
holes and insert the 4 long screws supplied to
attach gauge. Next, hold gauge/adapter plate
up to the test stand mounting plate. Insert bolts
supplied through the mounting plate into PEM
nuts on the adapter plate. (FIG. 3)

2. Loosen the allen screw in the limit (A), adjust
your stop position, and re-tighten the screw.

Support the gauge/mounting plate with your
hand when moving the limit so the gauge
will not fall to the base and be damaged!

3. If desired, replace the regular mounting plate
with the extender mounting plate to increase
gauge/base clearance to 10 inches.

Versatility

The DFG-TS Manual test stand can be configured to meet the needs of any com­pression/tension application. The standard configuration, DFG-TS-C, is with the
mounting plate to the front, lever to the right. Compression measurements are
made by pulling the lever down and toward you.

The following conversions can be made to convert the DFG-TS-C, to right or left
handed operation, to measure tension, or with the optional work table to hori-

zontal operation. (The DFG-TS-T, tension model, may similarly be converted).

Right or Left Handed Operation

Convert the stand to right or left handed use:

1. Remove the 4 screws holding the lever assembly (B) and pull out the assembly.

2. Mark the top side of the gearbox housing (C) and remove top plate (K).

3. Slide the gearbox housing (C) up and off the posts.

4. Turn the gearbox housing (C) over so that the top mark is down and the hole
for the lever assembly is on the opposite side and slide back on the posts.

5. Replace the lever assembly and 4 screws.

Convert Compression to Tension

DFG-TS-C, standard model, may be converted to test for tension 3 different ways.

Method A

Simply unscrew the lever and
re-locate to a different threaded
hole (FIG. 4).

Method B

Remove the mounting plate and
re-locate the mounting plate to
the back of the gearbox hous­ing. When you face the back of
the stand and pull the lever arm
down the gauge will move up
(FIG 11 page 6).

Method C

Reverse the test stand posts.
When you face the front of the
test stand and pull the lever arm
down the gauge will move up
(FIG. 5).

1. Remove the 4 screws holding
the lever assembly (B) and
pull out the assembly.

2. Remove top plate (K) and
slide the gearbox housing
(C) up and off the posts.

3. Remove compression spring (J).

5. Tap out the posts with a rubber mallet.

6. Reverse the positions of the gear and guide
posts and reinsert the posts being careful to
align the small hole in the bottom of each
post with the spring clip (H) near the large
hole in the base (FIG. 7).

7. Replace and loosely tighten the post nuts (G).

8. Slide the gearbox housing (C) over the posts
and replace the lever assembly (B) before
completely tightening nuts to assure smooth
operation.

9. Mount the gauge to test for tension. The
stand has been converted to Model DFG-TS-T.

4. Turn the stand over and insert the 2
base plate mount­ing screws (F)
about half way
into the base.
Remove the 2 post nuts
(G) holding the posts, use sec­ond wrench for leverage as shown
in (FIG. 6). You will need a M16
socket wrench and a second open
ended wrench.

Oversize Objects

Adding Spacers

You can increase the distance between the gauge
shaft and the test stand post. Spacers may be
added between the mounting plate and the gear­box housing (C) using longer mounting screws.

Extender Plate

10" clearance may be obtained by
installing the optional extender
mounting plate (FIG. 10).

1. Remove the two screws holding
the regular mounting plate and
use them to install the extender
mounting plate.

2. Install the gauge using the 4
longer screws and the 8 spacers
included (2 spacers for each
screw).

Moving Mounting Plate

Especially long or wide objects may
be tested using the rear of the test
stand. (FIG. 11 & 12)

1. Construct a bridge to accommo­date wide objects or place the
stand near the edge of a bench
or table to test long items.

2. Remove the mounting plate and
place on the rear of the gearbox hous­ing (C).

3. Unscrew the lever and replace it in a
hole facing you.
