(Master gage is an optional accessory.)*3Indicators• Indicators for a Depth Gage is used for the Depth Gage. When the indicator is exchanged and extension rod is connected longer, the contact-point may incline signicantly.• Code No.543-400B / 543-402B for Depth Gage has a measuring force less than 1.5N.Extension rodContact pointMaster gage(optional accessory)
