Mounting Instructions
►Use two 3.0 mm x 0.5 mm thread machine screws to attach
to the bottom or rear 15200B/25200B/35200B 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.
►A light lm 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.

Connection to a PC using MEAS Adapters
Connect a 15200B/25200B/35200B to a 35250A, and connect a PC
COM port to the other side of the 35250A using the cable provided.
(If connecting to a PC with only a USB port, an RS232 to USB cable
will be needed). Plug power supply into wall and plug into power
jack on side of 35250A. Accelerometer should then be ready for use.

Notes:
Typical Settings Changed with ICU
►Accelerometer ranges (Range Hi and Range Lo)
►Low-pass lter settings (Filter 3 dB Cutoff)
►Resolution of high-speed data (IRIG Word Bits). Eight (8)
bit data can be set to increase data transfer rates.
►Temperature and accelerometer Channel Units. Each
channel can be congured to measure in units suitable for
your application.
►Inversion of the sensor channels (Invert). Each channel
output can be inverted for maximum exibility in your
measurements.
►The telemetry Bit Rate may be adjusted according to how
fast measurements need to take place. RS232 hardware
limits bit rate to 115kb.
Retrieving the Calibration Certicate
1. Connect to the unit with ICU.
2. At the bottom of the Congure window, click Reports.
3. A separate window opens with Report selections at the bottom.
Select the Calibration check box. The certicate will then be
displayed.

How to Use the 15200B / 25200B / 35200B
as an Analog Sensor
►If a Measurement Specialties 35250A PC Interface
Adapter is available, connect its sensor connector to the
15200B/25200B/35200B, apply power to the 35250A, and
connect a computer to the 35250A RS232 connector. A positive
acceleration (labeled on the accelerometer cover) causes a change
on the corresponding output.
►If a 35250A is not available, connect a +8.5 to 36 V 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
15200B/25200B/35200B.
►Optionally, connect a voltmeter or other instrument to each
15200B/25200B/35200B Analog Output and Signal-. For best
results, use a converter with an input impedance greater than
1 MΩ.
►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 Conguration Utility (ICU) software
from precisionsensors.meas-spec.com and use it to congure
the 15200B/25200B/35200B. When transmitting High Speed
Data to a PC, sample frequency should be at least 10 times the
lter bandwidth when linear interpolation is used for signal
reconstruction. Built-in low-pass ltering can be used to lower the
noise oor and eliminate spurious peak measurements from short-
duration shock impulses with insignicant energy content.
Installing and Using ICU
►First, uninstall any previous versions of ICU that may be
installed, then download Instrument Conguration Utility
(ICU) software from precisionsensors.meas-spec.com. Run
Setup_ICU.exe to install ICU.
►Start ICU. Use About/Setup to select your COM Port
and conrm the data directory. Select Conguration as the
Program Function and press OK.
►Press the Conguration button. ICU scans for any
instruments attached to the COM Port. If an instrument is
found, ICU connects and reads the instrument conguration.
►The 15200B/25200B/35200B comes ready from the factory.
If your application requires changes, use the Main tab
to change the telemetry and the channel tabs to edit each
channel. For each channel, check the Range Hi and Range
Lo and the Filter 3dB Cutoff. If changes are made, you must
press the Write Values to Instrument button. The password
as shipped from the factory is “si”.
►Use the High Speed Acquire button to collect and save data
to disk.
