Setup and Operation
Connecting the Vane
1. The vane plug is inserted in meter’s sensor jack at the top of meter. The plug
and jack are keyed so that the plug can only fit in the jack one way.
2. Turn the plug carefully until it lines up with the jack and then firmly push the
plug into place. Do not apply undue force or try to twist the plug side-to-side.
3. If the vane is not connected to the meter properly or if the sensor is defective,
the LCD will indicate “
OL
” in place of a temperature reading.
