APPENDIX D – ANALOG OUTPUTS (IF EQUIPPED)
If the instrument is equipped with the analog output option, there will be a five-
pin connector on the bottom of the instrument. Also, an analog output cable will
be included with the instrument. This cable will have a five-pin connector on
one end and four tinned wires on the other end.
The instrument will output a Voltage between 0 and 5 Volts that corresponds to
the Air Velocity and Temperature measured by the instrument. The output
range, pin assignments, and wire colors are given in the table below. Also
shown is a block diagram of the analog output circuit.
