figures is free with respect of the read-out limits (20000 counts).
The display will show the following:
By the numerical keyboard, set the desired final scale value (For
Example 2, this value is equal to 20.000 mA).
Push the FUNC push-button.
By the numerical keyboard, set the desired read-out assigned to the
final scale value (For Example 2 this value is equal to 20.000 rpm).
Push the FUNC push-button.
NOTE For the read-out in eng. units, the number of decimal figures will
be equal to the decimal figure programmed in "L.RNG EU".
The instrument will start to measure and, for Example 2, if a 13 mA
signal is applied to the input terminal the display will show:
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.
The two potentiometers allow to change the load of the instrument
under test in order to make the measure of the MEMOCAL 2000
equal to the desired value and to verify the indication of the
instrument under test.
3.10.3 - RNG ( ) - TX simulation 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 3: it is desired to simulate a 2-wire transmitter with a
quadratic output range from 4 to 20 mA the "mA measuring device
with auxiliary power supply" is programmed for a read-out going
from 5.00 to 200.00 (m
3
/h) but it is desired to have on the device
and on the calibrator the same read-out scaling.
Pushing s or t push-button, select the RNG( ) function.
Push the FUNC push-button, the display will show the following:
H.RNG XXXXXX mA
H.RNG XXXXXX EU
MEAS RNG(L)mA
