Extended Product Information

FAQs

What is the total measurement range?

The indicator has a total range of 0-25.4 mm.

Is the measurement accuracy consistent?

Yes, it provides an accuracy of 0.03 mm, suitable for standard shop tolerances.

Can this be used on non-ferrous surfaces?

If the base relies on a magnet, it will only stick to ferrous surfaces; however, the dual-rod stand can be clamped if mounting options are available.

How do I maintain the fine adjustment?

Keep the screw threads clean and lightly lubricated, and avoid over-tightening the adjustment knob.

Is a storage case included?

Yes, a durable storage case is included to protect the indicator when not in use.

What is the diameter of the dial face?

The dial face is 2.4 inches in diameter for easy reading.

Troubleshooting

Needle sticks or moves erratically

Ensure the contact point is not being pushed beyond its mechanical limit and clear any metal dust or debris from the pivot area.

Reading fluctuates significantly

Check that the dual-rod stand is locked firmly and that there are no loose vibrations transferring through the machine bed.

Dial face is hard to read in low light

Ensure the dial cover is clean; if glare persists, slightly adjust the angle of the dial relative to your primary light source.

Pros and Cons

Pros

  • Large, high-visibility dial face
  • Sturdy dual-rod support for reduced vibration
  • Excellent reach for complex machine setups
  • Hardened construction for workshop durability
  • Includes a comprehensive storage kit

Cons

  • Requires careful calibration before first use
  • The arm tensioner can be sensitive to over-tightening
  • Not suitable for outdoor or high-humidity environments

Setup, Compatibility & Care

Setup begins by ensuring all joints of the dual-rod arm are clean and free of metal shavings. Tighten the locking knobs firmly but avoid excessive force to prevent stripping the threads. For compatibility, the magnetic or mechanical base is designed to mount securely to standard ferrous surfaces found on most milling machines and lathes.

Care instructions are vital for longevity. Never force the contact point beyond its intended travel limit, as this can damage the internal gearing. Clean the device regularly with a lint-free cloth and a light machine oil. When not in use, always store the indicator in its provided case in a cool, dry environment to protect against temperature-induced calibration drift.
