ANALOG OUTPUT
The MultiRanger Plus can be programmed to provide analog output (P-6) of 0 or
4 - 20 mA, proportional or inverse span.
The 4 and 20 mA levels can be trimmed slightly via P-97 and P-98 respectively
to compensate for any offset between the MultiRanger Plus and the
customer’s equipment.
The analog output feature can be turned OFF by setting P-6=0. The output and
alternate displays(5 &P-92) will immediately drop to 0 mA after a new measurement
is processed. The output will remain disabled during simulation (P-76,77, & 78)
However, the test routine of P- 92 and the trim parameters will remain active.
If P-60 = 0, then the analog output will return to its programmed output after a new
measurement is processed.
If the analog output must be isolated, the optional LIs-1 mA isolator must be mounted
on the motherboard and wired. When using the isolator, the load adjust can be done
via P-97 and 98 rather than via the load adjust potentiometer.
The analog output responds in the following manner :
