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, CONNECTIONS AND COMPONENTS SHOULD BE 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 DG Series User Manual 3 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. 4 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. Test Stand Adapters Item No. SPK-MT-0005 SPK-DG-TT Fits Tester MT150, MT500 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.
