Mounting Instructions
Use two 3,0 x 0,5 mm thread machine screws to attach to the
bottom or rear 25203A mount faces. 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.

How to Use the 25203A
If a Summit Instruments 35250A PC Interface Adapter is
available, connect its sensor connector to the 25203A, apply
power to the 35250A, and connect a computer to the 35250A
RS232 connector. 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 25203A.
➤ Optionally connect a voltmeter or other instrument to each
25203A 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 25203A.
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.
