What type of batteries do these readouts use? |
The WR750 Fence Readout uses two AAA batteries. |

How Long does the battery last if I turn off the readout?
How long does the battery last? |
The battery life should be 6 months with the unit turned on or off. Because the readout always maintains the calibration even when it is turned off, it is actually reading all the time. Turning it off only turns off the display which takes almost no power to run. Removing the battery is the only way to conserve it's life but then you have to recalibrate every time. |

How does it read? |
All of our readouts use what's called capacitive measuring technology. This is the exact same system that is used in almost all digital calipers that have been on the market for at least 20 years. There is a circuit board on the scale part of the device that has a repeating pattern etched on it. The readout portion has another circuit board with a similar pattern and the rest of the electronics. As the 2 patterns pass over each other there is an electronic signal generated that is converted to distance. The only moving part is the circuit board of the readout passing over the circuit board on the scale. There is no electrical connection between the 2 circuits boards and they do not even touch each other. There are no other mechanical moving parts. This makes the device very reliable and resistant to problems caused by dust. |

How long can the WR750 Fence Readout measure? |
The WR750 can measure 36 inch to the right of blade 12 inch to the left |
|
Do you have a height gauge to measure table saw blade height? |
No. Most likely this type of system will need to be built into when it is manufactured. It will be difficult to make an add on kit. |

Why aren't the fractions displayed all the time? |
The fractions work in a unique but highly accurate manner. The fractions will only display when the decimal reading is within + or - .002" of the fractions decimal equivalent. For example, if the display is reading .740" it will not display the 3/4" ( .750" equivalent) until after the readout passes .745". Internally the readout is actually measuring in .001" increments so that the 3/4" does not turn on until .748" and turns off again at .752" This gives your fraction readings a very high level of accuracy. |
