To use the DBK70 with a WaveBook, connect the DBK70’s analog outputs to unused WaveBook voltage
inputs using the optional CA-208 cable. A single CA-208 supports 8 channels; thus two CA-208 cables are
required to connect all 16 DBK70 analog outputs to a WaveBook and/or to any WaveBook expansion
modules.
In WaveView, the data acquisition software included with the WaveBook, use the mx+b (scale and offset)
feature to convert the DBK70 voltage values into engineering units. For example, if the DBK70 is
capturing vehicle RPM in the range of 0 to 5000 RPM and scaling the result to 0 to 5 volts, setting the “m”
in WaveView to 1000 will convert the incoming voltage to RPM. This technique can be used in any data
collection software package to convert the DBK70’s output voltage to engineering units.
Reference Note:
mx + b values are included in a Microsoft Excel file: mx+b values.xls. The file is
located in the root directory of your DBK Configuration CD (p/n 1056-0600).
