7. NTRODUCTION 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 Ibf 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 fixt
