| How long does the battery last? |
| The battery life should be over 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 reduces the power consumption by 50%. There is an auto shut off feature incase you forget to turn it off. |

| What type of batteries do these readouts use? |
| The WR200 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 a rotating counterweight that has a repeating pattern etched on it. There is a second fixed 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 rotation angle. The only moving part is the circuit board with counterweight passing over the fixed circuit board. 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. |
