The ergonomically designed FDL Force Dial™ Push - Pull
Force Gage features an impressive ±0.3% accuracy. Avail-
able in seven capacities, all models have dual graduations in
pounds and kilograms. The FDL mounts directly onto Wagner
test stands with American standard threads and is easily
mounted onto other single column test stands with optional
mounting adapters. Optional handles and a variety of gripping
fixtures are available.

• Prior to using the FDL, the accuracy should be veri-
fied by testing with weights - see "CALIBRATION"
section.
• Forces must be applied to the load shaft only in an
axial manner. Applying a load at an angle can cause
an error in readings and possibly damage the gage.
• Force measurements can be made with the FDL in
any position - pull at the top and push at the bottom
- since changes in the pointer's zero system due to
the effect of gravity are compensated by rotating the
dial bezel.
• Attachments installed on the shaft should only be
finger tight. Use of a tool may cause internal damage
to the gage.
• Lubrication of the FDK/FDN is not recommended
since oil will accumulate dust resulting in
increased friction and decreased accuracy.
1 kgf x 0.01 kgf
• Use of the FDL in the lower end of its range may
3 kgf x 0.025 kgf
produce inaccurate results. Another model with a
5 kgf x 0.05 kgf
lower capacity may be necessary. The FDL is built
10 kgf x 0.1 kgf
to the accuracy stated, but may be used in its lower
20 kgf x 0.2 kgf
range if the gage is tested in that range and found to
30 kgf x 0.25 kgf
meet user requirements.
50 kgf x 0.5 kgf
• Call Wagner Instruments with questions regarding
the use of the FDL in your application.
• The maximum force applied to the FDL is retained
by the peak hold switch located on the upper right
side of the gage. The peak reading is saved by the
pointer remaining at the maximum force applied
after the force has been removed.
To activate, press the switch to "ON". To release the
peak and return the pointer to zero, press the switch
to "OFF".

CALIBRATION
• The accuracy of the FDL is ±0.3% of full scale. To
calculate the possible error in lbf or kgf of your FDL
multiply the gage capacity by .003.
Example for an FDL 100:
100 lbf x 0.003 = ± 0.3 lbf
Thus, the possible error can be ±0.3 lbf at any read-
ing on the dial from 0-100 lbf.
• Prior to shipping, the FDL is calibrated with certified
test weights. Since rough handling during shipment
may affect the accuracy of the FDL, it is recom-
mended that the accuracy be verified prior to use by
suspending one or more known weights on the FDL.
• Periodical testing of the FDL accuracy should
be performed with certified test weights. It is sug-
gested that weights be suspended on the securely
mounted gage at 1/4, 1/2, 3/4 and full capacity.
• Do not attempt to adjust the FDL. If it is found
inaccurate contact Wagner Instruments.
• When using the FDL, position the pointer by rotating
the dial to the "ZERO" position before applying force
to the gage.
MOUNTING
• American Standard 10-32 thread mounting holes
are provided on the rear side of the FDL for mount-
ing to a test stand or fixtures. The mounting hole pat-
tern is compatible with many test stands. The pattern
contains two #10-32 threaded holes, 2-1/4 " apart
on the vertical centerline. A third 3/16" unthreaded
clearance hole is provided for a dowel pin, found on
some test stands for suspension of the force gage.
Mounting screws should penetrate the gage no
more than 5/16".
