DEPTH MICROMETER OPERATION MANUAL

  1. Interchangeable rob
  2. Base
  3. Sleeve
  4. Locking device
  5. Thimble
  6. Ratchet stop
  7. Spanner

1. Zero Setting

  • Before using, clean the measuring face of the interchangeable rob and the face of the base with a soft cloth or soft paper. The zero position is set on an accurate flat with 25mm/1" interchangeable rob. Put on relative rob according to the measuring range, not necessary to reset when changing rob. If the line marked "0" on the thimble does not coincide with the reference line on the sleeve, adjust the zero position in the following manners.

1) Deviation within ±0.001" (or ±0.01mm)

  • Lock the spindle with the locking device then adjust the sleeve with a spanner until the reference line comes exactly in line with the "0" line on the thimble.

2) Deviation over ±0.001" (or ±0.01 mm)

  • Lock the spindle with the locking device and lose the ratchet stop by a spanner. Pressing the thimble to the ratchet stop brings it so that the "0" line coincides with the reference line on the sleeve. Fasten the ratchet stop and make the final adjustment.
  • If necessary, in the former way.

Works well BUT pins fall right out of checking something vertically and have a useless taper that makes it hard to check narrow surfaces.

Was shocked how good this is for the price. If you know how to adjust the zero they passed inspection at my work.

That’s my biggest complaint. Seemed nice otherwise. Even came with a hand signed certification of accuracy. Didn’t test accuracy, just returned immediately. I’m upset about the minuscule line in the description. I need flat ended rods to measure ledges.

I should've bought a Fowler . Or , a different brand name I've been using for decades . Tried to save a little cake , oh well . Probably pass this on as a secret Santa gift.

Better than calipers because of the larger "flat" reference surface but using the rachetyields the advertised +- 0.0002 precision.BTW, the rachet was disassembled upon arrival (2 collars, a spring, a screw, and a barrelfloating in an unsealed plastic bag.

Way over price for an almost unusable depth gage. I wish they would have mentioned that in there description of this depth micrometer set had fully rounded tip and not flat tip. I would never bought it. Waist of money.

I have the 0-6" set and they are mediocre. Doesn't stay calibrated. Everytime you change the measurement rod it has to be recalibrate and even then it's not trustworthy. Mitutoyo is the best for depth mics.
