NOTES:
1) For the read-out in eng. units, the number of decimal figures will
be equal to the decimal figure programmed in "L.RANGE EU".
2) During a mA generation with programmable read-out scaling, it is
possible to enable/disable, by the REV/MOD push-button, the
scaling function and to display the generated value in mA.
The instrument will show:
By the numerical keyboard, set the value to be generate.
Push the FUNC push-button, the instrument start immediately to
generate.
3.9.3 - RNG (QUAD) - mA generation with quadratic output and
linear read-out scaling.
Selecting the RNG (QUAD) option, the value to be generated will be
set in engineering unit and it will be linear while the resulting output
will follow quadratic curve.
Example 2 : with a quadratic output range from 4 to 20 mA it is
desired to have a read-out going from 5.00 to 200.00 (m
3
/h).
Pushing s or t push-button, select the RNG(QUAD) function.
Push the FUNC push-button, the display will show the following:
By the numerical keyboard, set the desired initial scale value (For
Example 2 it 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 (For Example 2, it is equal to 5.00 m
3
/h.)
Depress the FUNC push-button.
NOTES: The displayed range will only be represented with positive
numbers.
The display will show the following:
OUT RNG(L) mA
XXXXXX EU
L.RNG XXXXXX mA
L.RNG XXXXXX EU
