the SAA232 device to your laptop by means of a “SAA232-USB” Connector (Figure 3.1). The SAA232-USB
4-pin green connector plugs into the top receptacle on the SAA232. Power is supplied to the SAA232 by
connecting the red (12V) and black (Ground) wires to available ports on the CR1000 (Figure 2.2). The
USB connector is then plugged into an available USB port on a computer running SAARecorder. For more
details about SAARecorder, consult the SAARecorder Manual included in the installation.
Once connected to the SAA using the SAA232-USB, open SAARecorder and connect to the SAA. In
SAARecorder, click on Actions | Advanced | Diagnostic Test and then click on ‘Total Acceleration Check’
(Figure 3.2). A plot showing the total acceleration levels for each segment appears (Figure 3.3). Verify
that all values lie between 0.93 G and 1.07 G. If this is not the case, please contact Measurand for
further diagnostic support.
SAA roll calibration can also be performed by connecting to an SAA in this manner. SAA is shipped with a
factory roll calibration, ready for installation. It is wise to check the roll calibration on subsequent
installations. The method for doing so is described in the SAA Installations Guide, available from the
Measurand website (http://MeasurandGeotechnical.com/Installation_Guide_2011.pdf). If you have any
issues with the calibration, please contact Measurand.
