WARNING
The raised hand icon warns of a situation or condition that may lead to personal injury
or death. Do not proceed until the warning is read and thoroughly understood.
Warning messages are shown in bold type.
DANGEROUS VOLTAGE
The lightning icon warns of the presence of an uninsulated dangerous voltage within
the product enclosure that might be of sufficient magnitude to cause serious shocks
or death. Never open the enclosures unless you are an authorized and qualified
CHATILLON service personnel. Never open any enclosure when power is connected
to the system or its components.
CAUTION
The exclamation point icon indicates a situation or condition that may lead to equipment malfunction or damage. Do not proceed until the caution message is read and
thoroughly understood. Caution messages are shown in bold type.
NOTE
The note icon indicates additional or supplementary information about the action,
activity or concept. Notes are shown in bold type.
CAUTION
HIGH FORCES ARE OFTEN INVOLVED WITH THE
MATERIAL TESTING PROCESSES.
IF THE EQUIPMENT IS USED IN A MANOR NOT
SPECIFIED BY THE MANUFACTURER, THE
PROTECTION PROVIDED BY THE EQUIPMENT MAY
BE IMPAIRED.
TO MAINTAIN ALL ASPECTS OF THE SPECIFICATION,
ONLY AMETEK APPROVED ACCESSORIES,

USED.
STRICTLY ADHERE TO ALL SPECIFIED SAFETY
PROCEDURES
READ THIS MANUAL BEFORE USING THIS PRODUCT.
General Safety
General safety precautions must be followed when
using this CHATILLON product. Failure to observe
precautions and warnings may result in damage to
the equipment, or injury to personnel.
It is understood that safety rules within companies
vary. If a conflict exists between the material
contained in all CHATILLON User’s Guides and the
rules of a company using a CHATILLON product,
the more stringent rules should take precedence.
Safety Considerations
The DG Series is completely enclosed and provides no potentially hazardous outputs.
Mechanical components housed within the DG
Series covers are to be serviced by authorized
CHATILLON representatives only.
When designing a custom fixture ensure
the load rating of the custom fixture exceeds the load rating of the force gauge.
i.e. If the load rating of the force gauge
is 500 LBF the custom fixture should have a load
rating greater than 500 LBF

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: 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.
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.

DG Series User Manual
PEAK HOLD
The DG 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 DG Series force gauge has four #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.

TT Testers
The screw thread length going into the back of the
gauge should not exceed 3/8 inch.
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.
