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 +VS Connect power source ground to the Gnd pin. Connect a computer RS485 interface to the two RS485 pins on the 35203A. ➤ Optionally connect a voltmeter or other instrument to each 35203A Analog Output and Signal-. For best results use a converter with an input impedance greater than 1MΩ. ➤ Keep cable lengths between an analog output and an instrument as short as practical. Use shielded twisted pair wiring, especially near electric motors or other noise sources. ➤ Download Instrument Configuration Utility (ICU) software from www.summitinstruments.com and use it to configure the 35203A. When transmitting High Speed Data to a PC, sample frequency should be at least 10 times the 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. ➤ Specifications* Accelerometer(s) Maximum Full Scale Range Sens.
