NOTES:
1) The instrument will automatically select the input range contain-
ing the two programmed values ("L.RANGE mA" and "H.RANGE
mA") with the maximum resolution.
2) During mA measurement with programmable read-out scaling it is
possible to enable/disable, by the REV/MOD push-button, the
scaling function and to display the measured value in mA.
3) During mA measurement, the instrument is able to measure and
display up to 5 % more than the upper programmed value or 5%
less than the lower programmed value.
3.4.3 - RNG ( ) - mA measurement with square root extraction
and linear read-out scaling.
Selecting the RNG ( ) option, the instrument extracts the square
root of the measured value and scales it according to the pro-
grammed range.
Example 2 : with a quadratic input 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( ) function.
MEAS RNG(L)mA
-3.000 EU
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 to 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:
1) The input range may contain negative values.
2) The displayed range will only be represented with positive
numbers.
