Precision is 0.0002″. Height can be adjusted by 2″. Base made of magnet.
When the red lamp is touched, it illuminates in all directions.
Introduce the tool to the unit until the light is turned on, then pull the tool away until the light is turned off again.
When setting the diameter, rotate the tool slowly to ensure greater precision.
For the presetting unit, only a gauge block and a preset gauge should be used instead of a caliper.
When the red lamp is touched, it illuminates in all directions. 2″ Magnetic base with accuracy of 0.0002″ Adjustable height of 2. Introduce the tool to the unit until the light is turned on, then slowly withdraw the tool until the light is turned off. Adjust the height of the unit if necessary by turning the top grey portion of the unit alongside the center threaded body, which is secured by two all-in screws on the side of the unit. When setting the diameter, rotate the dial too slowly to achieve higher precision. Presetting unit should not be used with a caliper; instead, a gage block and preset gauge should be used.
The threads were rough, the batteries were dead when they arrived, and it took far too much effort to get the machine to be accurate. I’d like to come back if I could, but for the time being, this is all I have.
