| How long does the battery last? |
| The battery life should be 6-12 months under normal use. There is an auto shut off feature that completely shuts down the device after 6 hours to conserve the battery. |

What type of batteries do these readouts use? |
| The WR25 Mini Digital Height Gauge uses a CR2032 watch battery. |

| 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. |

| 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 .747" it will not display the 3/4" ( .750" equivalent) until after the readout passes .748". and turns off again at .752" This gives your fraction readings a very high level of accuracy. |
