(Master gage is an optional accessory.)Note 3Caution 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 deect signicantly with an adverse effect on measuring accuracy.• Order No.543-400B/543-402B for Depth Gage has a measuring force less than 1.5 N.Extension rodContact pointMaster gage(optional accessory)●No.7220A、7221Aはダイヤルゲージの 取付位置を変えることができます。7220A and 7221A allow the mounting position of a dial indicator to be varied.7211A7224A7231A7214A7222A
