Operation

Connecting the Vane

1. The vane plug is inserted in the meter’s sensor jack at the top of the 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 in

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 or if the sensor is defective, the LCD display

will indicate OL in place of a Temperature reading.

the temperature reading.
