6. Question Answer StrainBook 616 User s Manual Why can t I use the external clock feature on the WBK14 to control my acquisition speed The external clock on the WBK 14 is used to dynamically move the corner frequency of the filter not pace the A D in the StrainBook This feature is often required in vibration applications where the filter is moved as the device under test is vibrated or excited at varying frequencies Is there anything special I should know about WBK14 s power up state At power up the current output of the WBK14 is open circuited It is only after being programmed that the current source is engaged In regard to attenuation what is the filter roll off for the WBK14 filter The WBK 14 s Butterworth filter is down 3 dB at the corner frequency Beyond that point the signal attenuates at 48 dB per octave or 160 dB per decade This is a substantial amount of attenuation for most applications 968594 Troubleshooting 11 11 Question Does the StrainBook really collect data at 1 MHz and what should I expect on my PC Answer Yes the StrainBook samples at 1 MHz But your computer may not The PC s performance is a function of the hardware configuration operating system background task and other factors The PC could very well be a bottleneck in regard to sampling Question Should I calibrate my StrainBook system when I receive it Answer No because each StrainBook and WBK is factory calibrated to

Resistors are positioned wrong and or poorly soldered Calibration parameters are invalid Active Bridge Elements or Load Cell are not adequately powered Details and Possible Solutions If the bridge completion resistors BCRs and or shunt calibration resistors were improperly positioned or poorly soldered the WBK16 will not calibrate properly Check the BCR and shunt arrangements for the applicable bridge configuration Also verify that the BCRs and shunt resistors are properly soldered Test the solder joints by measuring the resistors through the header pins which they are soldered to If they don t measure within the allowed tolerance the associated resistors should be unsoldered the old solder removed and then the resistors should be properly re soldered The WBK16 s hardware setup section in the WBK Options Manual includes illustrations of various bridge configurations A PDF version of the document is included on the data acquisition CD If invalid calibration parameters are entered into the WBK16 s calibration program the channels will not calibrate correctly See note If using shunt cal make sure that the resistor values used are actually simulating the expected amount of bridge deflection Verify that units are used consistently in all pertinent entry fields For example if you enter the maximum applied load as units of micro strain then enter the shunt units in units of micro strain too For addi
