Question about Measuring Tools

1 Answer

Need to get my good old DRO to work again.

I have a Mitutoyo PLL32L ( S/no. 900185 ) Linear scale fitted to a Colchester Chipmaster Lathe with cross slide and bed scales. It used to work 100% before my workshop move. Now when I plug it all in all ( after 2 years in storeage) I get are rows of ------------ on both the upper and lower X & Y readouts. There has been no damage to the equipment, and it shows this same display with or without the scales connected!!.

Try to clean up the linear scale first, maybe the light did not reflect because of dirt or dust

Mitutoyo 543-256 linear error of 0.028mm over full 12mm stroke. Repeatability is perfect, mechanically is perfect. Is there a re-calibration procedure?


Ensure your testing procedure is perfect. If your testing procedure is proven, then you will need to send it for repair. At that point, either your scale or grid assembly is damaged or requires adjusting.

Scale is reading F--H


Mine did this also, I got a replacement and it also read F--H. I took all the screws out - they hid them under the bar code sticker and under the stick-on faceplate where the buttons are - then found that the screws on the load cell which is sort of like an aluminum tuning fork had been tightened so much that the cell was reacting to the screw force, not the scale pad. Release all the pressure and you may be able to make it come alive again. One of my two is working now but calibrating is another thing all together because the linear counting depends on the loadcell screws being set just right.

I have a mitutoyo dial depth gauge. How do I use and read this?


A dial depth gage should have a set of depth stems. they are in 1" increments. to change the stem, first using a scale, measure the depth of the hole you are checking. Find the stem that falls in that range. remove the cap on the top of the unit, pull the existing stem out and replace it with the stem you need to reach the bottom of the hole. replace the screw-on cap. Set the cross bar of the body on the face of the part. Gently turn the barrel until the stem touches the bottom. the barrel has a 1" range. The numbers represent .1". The lines between the numbers represent .025". One turn of the dial equals .025" Add the length of the stem, the number on the barrel, the number on the dial and the number diall. Example, If the hole measures between 3" and 4" i.e. (3-1/8")start by installing the 3 to 4" stem. Turn the barrel so it reads "0". place the cross bar of the body so it touches the face perpendicular to the hole. Gently turn the barrel of the unit until it stops at the bottom of the hole. Add 3" plus the number on the barrel (.1"), the number of graduations on the barrel, and the number on the dial (.023"). The reading is 3.123". If you know your decimal equivalents, you will know that the hole is .002" short of 3.125" (or 3-1/8" deep.

I have a mitutoyo digital caliper model 500-230. i replaced the battery but when i pressed the on/zero button the display keeps running like its counting down and will not stop. The in/mm button seems to...


Sounds like the new battery you installed is no good. Is the display also dim? When the battery is low that is one of the results on the Mitutoyo. Do you have another battery to try in it?

Adjusting the angle of the contact point on a Mitutoyo 513-402


By simply pushing it (the contact point), it may be stiff to start but should ease up over time. Remember if your doing precision work (0.001mm or seconds of a degree) changing this original position will affect your reading so refer to booklet within original packaging or visit mitutoyo website's (Japan, USA, UK) between them they have most instructions available it's just a question of finding it, Good Luck.
