DG Series User Manual
iNTRODUcTiON
The DG Series mechanical force gauge is ideal for a wide range of force testing applications. Based on
our popular DPPH Series force gauge, the DG Series features a 2.25-inch dial for improved resolution and
readability, peak hold button, ergonomic shape and improved accuracy of +0.5% of full scale. The DG
gauge is an excellent, economical solution for tensile or compression testing.
The DG series gauge can be used as a hand held device with a handle adapter assembly that can be
purchased separately. 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. DG Series gauges come complete with protective carrying case and a set of stainless
steel attachments. A Certificate 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 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.
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 fixtures 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 “finger-tight”.
Do NOT overtighten.
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:
The DG 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 DG 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.
