Be careful not to bottom screws in tapped holes as this can strip threads. ➤ A light film of oil or silicone grease can be used to enhance contact between mounting surfaces. ➤ A locking compound should be used on all threads to prevent screws loosening due to vibrations. ➤ INSTRUMENTS Summit Instruments, Inc. 2 2 3 6 N .

A positive acceleration (labeled on the accelerometer cover) causes a positive change on the corresponding output. ➤ If a 35250A is not available, connect a +8 to 30V DC power source to +V Connect power source ground to the Power Gnd pin. Connect a computer RS485 interface to the two RS485 pins on the 25200A.. ➤ Optionally connect a differential or floating input A/D converter to each 25200A analog output and Signal Gnd. For best results use a converter with an input impedance greater than 1MΩ and common mode rejection ratio greater than 60dB. Less critical applications using single-ended converters should leave the signal ground pins unconnected to eliminate ground loops. ➤ Keep cable lengths between an analog output and an A/D converter as short as practical. Use shielded twisted pair wiring, especially near electric motors or other noise sources. ➤ Download ICU software from www.summitinstruments.com and use it to configure the 25200A. As a rule of thumb, sample frequency should set at least 10 times the highest filter bandwidth when linear interpolation is used for signal reconstruction. Built-in low-pass filtering can be used to lower the noise floor and eliminate spurious peak measurements from short-duration shock impulses with insignificant energy content. ➤ S Specifications* Accelerometer(s) Measurement Full Scale Sens.
