Speed: analog output (Universal+ only)
A current analog signal within the range 4-20mA into 250Ω impedance is available
between pin three and pin four of the output connector. The current is fixed
and directly proportional to the pumphead rotation speed. 4mA = zero speed;
20mA = maximum speed.
Note: If the mA output is to be used for reading from a multimeter, a 250Ω resistor
is required in series.
