7. ION 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 fits naturally in the hand for a comfortable and firm 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 Ibf kgf or N units of measure LG 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 fi 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 n
