Be careful not to bottom screws in tapped holes as this can strip threads. Alternatively, the two thru holes allow two #6 or two 3,5 mm screws to be used to mount the 23200B from the top. ➤ 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. ➤ SUMMIT INSTRUMENTS Summit Instruments, Inc. 2 2 3 6 N .

Connect a differential or floating input A/D converter to each signal and signal common pins (pins 5 and 6 for Accelerometer 1, pins 1 and 2 for Accelerometer 2, and pins 3 and 2 for Temperature). For best results use a converter with an input impedance greater than 1MΩ and common mode rejection ratio greater than 60dB. Single-ended converters are not recommended but if used, leave Signal Common unconnected to eliminate ground loops. A positive acceleration (labeled on the accelerometer cover) causes a positive change on the corresponding output. ➤ Keep cable lengths between the accelerometer and A/D converter as short as practical. Use shielded twisted pair wiring, especially near electric motors or other noise sources. ➤ As a rule of thumb, sample frequency should be at least 10 times the signal bandwidth when linear interpolation is used for signal reconstruction. Built-in or external 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. ➤ A logic 1 on the self-test input will add 0.25 to 0.6V* to both accelerometer outputs. An output that changes less than +0.25V* or more than +0.6V* indicates a defective channel, shorted pin, or broken wire. The self-test signal is approximate and should not be used for calibration. If the self-test feature will not be used, pin 7 should be connected to pin 9. ➤ ➤ * Scale linearly with range option Rnnn.
