Mini Digital Height Gauge WR25 - Battery Life
The subject Item, not bought from Woodcraft as far as I can determine, exhibits battery drain when the tool is OFF, to such a degree that the battery is fully drained between uses that may exceed a couple of weeks. Regardless of the Auto-Off feature, I am careful to turn the unit off after each use. This battery drain is unacceptable, and makes use of the tool a nuisance. A tag on the unit reading “QC 1142” may be helpful to assess the condition. This problamatic condition was not described at the time I bought this otherwise helpful tool. I took the time to read the FAQs for the WR25. and then read the FAQs referring to the WR200, some information of which appears to apply also to the WR25. Frequently Asked Questions for WR25 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. Frequently Asked Questions for WR200 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. I deduce that the continuous-calibration attribute of the WR25 may contribute to the very short battery life. Because the #CR2032 battery is relatively easily accessible, and now that I know that there is the described battery drain, in my case, possibly the result of an internal wiring flaw on this unit, I can remove the battery when the tool is not in use, thus preserving the life of the battery.
Set up with this tool is so much easier. Wish I would have bought this thing years ago.
Handy, inexpensive alternative to an expensive height/depth gauge.
Love my digital height gauge
I used it to set table saw blade and routor bits to proper height. Much easier than measuring with a tape measure or straight rule.
Accurate and easy to use. It lays flat, so it is also useful for setting bit distance from the fence. Easier and more accurate than using a combination square. Very much worth the money.
Quick, Fast and Accurate.
Quick, Fast and Accurate. If you like any of these attributes in your shop, then this little beauty should fit right in. I know there are reliable metal setup tools that do the same thing. The work....and they work well. This thing works Great. Use it to recheck dado or rabbits depth. This tool will not be used just on the router table or table saw. Saves me time and gets me back to making dust.
