*1 Caution should be exercised when exchanging a contact point of a Depth Gage (Dial / Digimatic Indicator):
• If a different size contact point is mounted, displacement of the contact point from the base contact surface will be changed and as a result, measurement range may not be maintained.
• A contact point cannot be mounted to a Depth Gage if its diameter is too large for the hole diameter of the base.
• Parallelism adjustment with the bottom face of the base is required when mounting a flat contact point such as the flat / needle or carbide-tipped contact point. *2 Caution should be exercised when using an extension rod:
• If the total length of the extension rod exceeds 110 mm (4.5 in) use the instrument in a vertical position (contact point downward).
• Use a master gage (such as gauge blocks) to perform zero-setting when the extension rod is mounted. (Master gage is an optional accessory.)
*3 Caution should be exercised when indicators are used on a Depth Gage:
• When the indicator is exchanged and a longer extension rod is connected, the contact-point may deflect significantly with an adverse effect on measuring accuracy.
• Code No.543-710B/543-712B for Depth Gage has a measuring force less than 1.5 N.
