4 LG Series User Manual
INTRODUCTION
The LG Series mechanical force gauge is ideal for a wide range of force testing applications. Based on our
popular DPP Series force gauge, the LG Series features a larger, 2.25-inch dial for improved resolution
and readability, peak hold button, ergonomic shape and improved accuracy of +0.5% of full scale. The LG
gauge is an excellent, economical solution for tensile or compression testing.
Thedurable,plastichousingtsnaturallyinthehandforacomfortableandrmgripevenatmaximum
loads. Gauges may be mounted to a test stand for even greater control and consistent results in
repetitive testing applications. Easy to read concentric dial measures clockwise direction only. Dial rotates
360-degrees for taring. A peak hold button captures peak readings. Available in lbf, kgf or N units of
measure. LG Series gauges come complete with protective carrying case and a set of stainless steel
attachments.ACerticateofCalibrationwithDataissuppliedstandard.
OPERATION
The zero point of the gauge may not always be in the 12 o’clock position due to gravity effects and the
weightofxturesorgripsontheforcegaugeshaft.Tozerothegauge,rotatethebezelonthedialindica-
tor 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 an angle or an error can be
introducedintheforcereadings.Thegaugesaredesignedtohavea10%tareforxturesandgrips.Ifthis
10% tare is exceeded, the force gauge may not measure up to full scale .
COMPRESSION TESTING
For compression testing, assemble the appropriate
attachment or grip to the bottom shaft of the force
gauge. For compression testing the shaft should
be pushed into the gauge, causing the indicator to
rotate in the clockwise direction. Attachments
shouldbeapplied“nger-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“nger-tight”.Do
NOT overtighten.
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.
CAUTION: NEVER 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.

LG Series User Manual 5
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
To reset the reading, simply rotate the switch to
“MAXOFF”andthenreturnbackto“MAXON”
position. To deactivate this feature, rotate the knob
tothe“MAXOFF”position.
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veried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.
