CHATILLON®LG Series
Mechanical Force Gauge
Operating Instructions
Instruction Manual NC002711
January 2003
TheLGSeriesmechanicalforcegauge
is ideal for a wide range of force test-
ing applications. Based on our popu-
lar DPP Series force gauge, the LG
Seriesfeaturesalarger,2.25-inchdial
for improved resolution and readabil-
ity,peakholdbutton,ergonomicshape
and improved accuracy of +0.5% of
full scale. The LG gauge is an excel-
lent, economical solution for tensile or
compression testing.
The durable, plastic housing fits natu-
rally in the hand for a comfortable and
firm grip even at maximum loads.
Gauges may be mounted to a test
stand for even greater control and con-
sistent results in repetitive testing ap-
plications. Easy to read concentric
dial measures clockwise direction
only. Dial rotates 360-degrees for tar-
ing. Apeak hold button capturespeak
readings. Available in lbf, kgf or N
units of measure. LG Series gauges
come complete with protective carry-
ing case and a set of stainless steel
attachments. A Certificate of Calibra-
tion with Data is supplied standard.

OPERATION
Thezeropointofthegaugemaynotalwaysbe in the 12 o’clock position
due to gravity effects and the weight of fixtures or grips on the force
gauge shaft. To zero the gauge, rotate the bezel on the dial indicator so
that the indicator pointer lines up with the zero on the dial face. On the
lighter model force gauges (5 LBF, 2KGF, 20N or less), gently tap the
gauge to overcome static friction when taking readings.
Gauges are designed for axial loading. Ensure the load is not applied at
anangleoranerrorcanbeintroducedinthe force readings. The gauges
are designed to have a 10% tare for fixtures and grips. If this 10% tare
is exceeded, the force gauge may not measure up to full scale.
CAUTION
The LG Series is a unidirectional force gauge. When applying a load
to the instrument the dial indicator MUST rotate in the clockwise
direction.
Compression Testing
For compression testing, as-
semble the appropriate attachment
or grip to the bottom shaft of the
force gauge. For compression
testing the shaft should be pushed
intothegauge,causingtheindica-
tor to rotate in the clockwise direc-
tion. Attachments should be ap-
plied “finger-tight”. Do NOT over-
tighten.
Tensile Testing
For tension testing, assemble the
appropriate hook, attachment or
grip to the top shaft of the force
gauge. For tension testing the
shaft should be pulled out of the
top of the force gauge, causing
the indicator to rotate in the
clockwise direction. Attachments
should be applied “finger-tight”.
Do NOT overtighten.

CAUTION
Do not apply a load to the LG Series force gauge so the indicator
rotates in the counterclockwise direction. If excessive loads are
applied in the counterclockwise direction, damage may occur to the
force gauge.
PEAK HOLD
The LG Series force gauge has
a maximum hold feature. This
allows the peak force to be held
after the load is removed.
Activate Peak Hold
To activate this feature, rotate the
knob to “MAX ON” position.
Reset Peak Hold
Toresetthereading,simplyrotate
the switch to “MAX OFF” and then
returnbackto“MAXON”position.
To deactivate this feature, rotate
the knob to the “MAX OFF” posi-
tion.

TEST STAND MOUNTING
The LG Series force gauge has two #10-32 female threads for
mounting to CHATILLON test stands. Ensure the #10-32 screws are
not too long, otherwise it may bind and damage the force gauge.
The screw thread length going into the back of the gauge should not
exceed 3/8 inch.
The force gauge also has four M3 x 0.5 threaded holes for alternative
mounting.

MAINTENANCE
Gauge accuracy should be checked periodically to ensure the gauge is
within its calibration limits. The calibration can be verified by applying
known weights (adjusted for local gravity) to the extension hook. If
adjustment is required, the gauge should be returned to AMETEK for
calibration.
