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.

*To convert from Volts to Air Velocity in Feet per Minute, multiply by 2000.
►
For example, an analog output of 2.375 Volts on the green wire means that
the instrument is measuring an air velocity of 4750 feet per minute (FPM).

2000 = 4750 FPM
*To convert from Volts to Temperature in degrees Celsius (°C), multiply by 20
and subtract 20.
►
For example, an analog output of 3.458 Volts on the white wire means that
the instrument is measuring a temperature of 49.16 °C.
►

Note:
When using analog outputs, there is an
additional ±1% error
in the
analog output voltage. This is in addition to the normal measurement error.
►
For example, an air velocity reading of 500 FPM would normally have an
accuracy of ±1% of reading ±1 digit (±6 FPM) when the data is viewed
on the LCD display.
►
With the additional error associated with the analog output voltage, the
effective accuracy of the analog output for this air velocity measurement
will be ±2% of reading ±1 digit (±11 FPM).
Custom Analog Voltage Outputs are also available – contact Kanomax for
details.
