Measurement Specialties, Inc. warrants this product against defects
in materials and workmanship for a period of three years from date of
shipment. During the warranty period, Measurement Specialties will, at
its option, either repair or replace products which prove to be defective.
Exclusions
This warranty does not apply to defects or damage resulting from:
•Improper installation or maintenance
•Customer supplied software or interfacing
•Unauthorized modification or misuse
•Operation outside of the product specifications
Limitations
The warranty set forth above is exclusive and no other warranty,
whether written or oral, is expressed or implied. Measurement
Specialties specifically disclaims the implied warranties of
merchantability and fitness for a particular purpose.
Some jurisdictions do not allow limitations on how long an implied
warranty lasts, so the above limitation or exclusion may not apply to
you. However, any implied warranty of merchantability or fitness is
limited to the three-year duration of this written warranty.
Warranty Service
To obtain service during the warranty period, products must be returned,
transportation prepaid, to Measurement Specialties.
13207A/23207A Rev. 8/14/13
How to Use the 13207A / 23207A
►►Connect a +8.5 to +36V DC power source to pin 8, ground to
pin 9.

Mounting Instructions
►►Use two 3.0 x 0.5 mm thread machine screws to attach to the
bottom or rear 13207A/23207A mount faces [recommended
torque 5 lbf-in (0.56 N.m)]. Be careful not to bottom screws
in tapped holes as this can strip threads. Alternatively, the two
through holes allow two #6 or two 3.5 mm screws to be used to
mount the 13207A/23207A from the top.
►►A light film of oil or silicone grease can be used to enhance contact
between two mounting surfaces.
►►A locking compound should be used on all threads to prevent
screws loosening due to vibrations.

CAUTION
Improper wiring, particularly +Vs, may cause
permanent damage and void the warranty.
Pins other than +Vs should not exceed 5 V.
►►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 60 dB.
Single-ended converters are not recommended, but if used, leave
Signal – (pins 2, 6) unconnected to eliminate ground loops. A
positive acceleration (marked on the accelerometer label) 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 0 on the self-test input will add to both accelerometer
outputs (see calibration certificate for amount). An output that
changes significantly more or less (±20%) than the certificate
amount 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 may be
left disconnected.
