DRO Installation Continued
Here are the brains of the digital readout. This unit
slides along the aluminum track reading the sensor strip. Now this can
be used on either side of the fence depending on your needs. The small
round pieces sticking out of each end are very strong magnets that come
in contact with a steel bracket that is mounted to your fence. Then when
you move your fence it also moves the DRO and lets you know
your distance, in both decimals and fractions.
The on/off/cal button turns the unit on and off and if
held down for three to five seconds goes into calibration mode.
The ABS/INC button does double duty. The ABS is for
'absolute measuring mode' (which you would use most of the time) and the
'incremental measuring mode' is like a secondary measurement, or
point-to-point measuring. However, if you do use the INC mode, make sure
to switch it back to ABS mode or you'll find that your measurement is
way off. Pushing the button once toggles between each mode.
There is a cover at the bottom that holds two AAA
batteries, that you have to supply.

The good news:
After messing with the calibration mode, I set my fence to
1/2", cut a piece of scrap and checked to see what size I had. And
if you look below you'll see that it's
almost perfect. However, I did get some varied results. I cut a few more pieces
to experiment if it repeats or not and so far this Wixey digital
readout is working pretty good.
-
It's easy to install and setup.
-
You can acquire a certain dimension very fast
without the use of a tape measure or a scale.
-
This unit also has an auto shut off, which means
extended battery life.
-
You have the option of using ABS or INC when
working.
-
You can remove the rip fence without loosing
calibration.
-
It's pretty accurate.
-
It will readout in decimal, fractions or metric.
-
Retains memory when you turn the unit off.
Now the bad news:
Before buying this unit I read that it
will measure to the third decimal place, which it does but only when the
appropriate fraction is being used, like 1/2" or 1/4", etc. However, the
rest of the time the Wixey DRO only reads out to two decimal places.
With that being said, you can move the fence a small amount in either
direction without the number changing. How much you ask? I put a dial
indicator on the fence to find out and it's between .005"
and .010". And Wixey claims the resolution is .005", which may not sound like much but I'm just not use to that
kind of inaccurately.
Final thoughts: Would I recommend this
digital readout to my friends? Yes I would. Let me explain: I happen to
be a special case because I've been a
machinist all my life and accuracy is the name of the game in that world. But this
isn't aerospace work, it's woodworking, which means
everything doesn't need or have to be that exact. With that being said,
this unit should work and please almost everyone that uses it.
