HOW TO EXECUTE A TX MEASUREMENT.
Push the MEAS push-button; the display will show:
Pushing s or t push-button, select the TX measurement.
Push the FUNC push-button; the display will show the following:
Where:
RNG(L)
means a linear input with programmable read-out scale in engineer-
ing units.
RNG( )
means a square root extraction of the measured value with
programmable read-out scale in engineering units .
3.5.1 RNG (L) TX measurement with linear input and
read-out scaling.
Example 1: with a linear input range from 4 to 20 mA it is desired
to have a read-out going from 1.00 to 10.00 (Bar).
Pushing s or t push-button select the RNG(L) scaling type.
Push the FUNC push-button, the display will show the following:
By the numerical keyboard, set the desired initial scale value (from
Example 1, this value is equal to 4.000 mA).
NOTES:
1) The value assigned to "H.RANGE mA" must be higher than the
value assigned to "L.RANGE mA" parameter.
2) The value assigned to "H.RANGE EU" parameter must be
different from the value assigned to "L.RANGE EU".
When conditions 1 or 2 are not satisfied, the instrument will reject
the new value showing the "0" and it will maintain the cursor on the
rejected parameter.
3) The value assigned to "H.RANGE EU" parameter can be lower
than the value assigned to "L.RANGE EU" (reverse read-out).
Push the FUNC push-button; the cursor will go automatically on the
lower line.
By the numerical keyboard, set the desired read-out assigned to the
initial scale value (from Example 1 this value is equal to 1.00 Bar).
Depress the FUNC push-button.
NOTES: The instrument uses the 20 mA input range.
For the read-out in eng. units, the number of decimal figures is free
with respect of the read-out limits (20000 counts).
