Measurement Computing DaqView - Manual (Page 71)

Using the Configure Engineering Units Dialog Box
You can use DaqView’s y = mx + b scaling factors by double-clicking in the channel’s Units cell.
This brings up the Configure Engineering Units dialog box (following figure).
Using the Configure Engineering Units Dialog Box
You can use the dialog box to compute the contribution of both 16-bit results to the final 32-bit result so
they appear as engineering units. You can manually add both numbers directly from the screen or later
during post analysis, from data saved in a file.
The appropriate conversions to use are as follows:
counter or totalize mode 32H*65535
32L
period modes
1
[32H*65535]*tickduration/number of periods
[32L]*tickduration/number of periods
pulsewidth
1
or timing
1
modes
[32H*65535]*tickduration
[32L]*tickduration
frequency mode (in Hz)
assuming counter mode
[32H*65535]*scan rate
[ 32L]*scan rate (Note 2)
1 time, e.g., seconds, nanoseconds, microseconds, or milliseconds
2 Where scan rate is expressed in units of: number of scans per second.
