By the numerical keyboard, set the desired final scale value (For
Example 2 it 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 it is equal to 200.00 m
3
/h).
NOTES:
1) For the read-out in eng. units, the number of decimal figures will
be equal to the decimal figure programmed in "L.RNG EU".
2) For the read-out in eng. units, the number of decimal figures is
free with respect of the read-out limits (20000 counts).
3) During 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 generation value in mA.
Push the FUNC push-button; the display will show:
By the numerical keyboard, set the value to be generate.
Push the FUNC push-button, the instrument start immediately to
generate.
3.10 - TX SIMULATION
NOTE: we define as TX all the 2, 3 or 4 -wire transmitters with 20
mA output capability.
CONNECTION FOR 2-WIRE TX SIMULATION.
For both potentiometers it is suggested to utilize 10 turn, 2 W,
linear potentiometers with the resistance shown in figure.
