DTI reading???? ****HELP PLEASE!****

[johnny_h]

Can someone tell me what this reading is?

 

 

I'm trying to time up my cam using the "HT method" in classic ford and have bought a DTI but can't read the fookin thing!

I was taught in metric but do know that Inches are measured in 8th's and 16th's but this gauge makes no sense at all.

Printed on the front is 0.005" so I guess that means the gauge is measured in five thousands of an inch. This is where it gets confusing. Do I need to divide the measurement by 5 to get the reading? Also the gauge reads clockwise 5, 10, 15, 20, 25 and then goes back 20, 15, 10 ,5 ???? This is a minus reading by the way.

 

Please help decipher this dinosaur language.

Just phoned Baty and found out the increments are half a though each. Still can't read it tho lol

That DTi is imperial, as you know, the incrememts are in ,0005, which is half a tho" each major section is between the figures is 5 thou, so each small incriment is half a thou, in reality you are only using it as a indicator to check rise and fall of the cam, so the type of DTi is not a problem,

you get about 4thou to every 1/10th of a mm

Reads 0.0925,

0.925 is nearly an inch, = about 24.5mm
