For example:
If the user wants to measure the percentage of pressure of gases in the pressure valve, then then user
needs to display the output in range of 0 to 100 %. So, here the span must be set as 100 by the user.
Span = (100-0).
Now, for the above case if the user wants to just measure the percentage of pressure if gone above
50% that is 50-100% then in this case the user must set the value of span as 50. Span = (100-50).
User can set the Span value anywhere between -3276.8 to 3276.7.
To set the Span for a channel then follow the procedure shown in figure- 40 by pressing the
appropriate buttons given in the front panel of the LmNet.
7.3.9.4 Offset
Offset is the amount of deviation that occurs in the output due to calibration errors of the sensor.
Thus, if there are deviations in the output compared to the expected output, offset value should be
set appropriately to null the effect of deviation.
7.3.9.5 Multiplier
Multiplier is a function given for the user flexibility. If the user wants to observe the output in the
range other than the actual output range, multiplier value must be set.
