How to Use the 34200A
Connect a +8 to +30V DC power source to pins 8 and 9.
Connect a differential or floating input A/D converter to each
signal and signal common pins (pins 1 and 2 for Accelerometer 1,
pins 3 and 2 for Accelerometer 2, pins 5 and 2 for Accelerometer
3, and pins 5 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 pin 2
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 all three
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.
Use two 3,0 x 0,5 mm thread machine screws to attach to one of
the three 34200A mounting faces. DO NOT thread a screw more
than 2.5 mm (0.100 inch or 5 turns) into any 34200A mounting
face as this can damage the accelerometer and will VOID the
warranty.
➤ A light film of oil or silicone grease can be used to enhance
contact between the mount and the 34200A.
➤ A locking compound should be used on all threads to prevent
screws loosening due to vibrations.
