Note 1: Limit hands, bezel clamps and lifting levers cannot be installed. Note 2: The shoulder on a contact point (standard accessory) acts as a stop to prevent spindle overrun that may otherwise damage the indicator. When replacing it with an optional contact point with a connector not exceeding ø7 mm in outside diameter, insert a washer (with ø7 mm outside diameter, ø3 mm inside diameter, and approximately 0.5 mm thickness) above the contact point. Note 3: B eing fixed by only two retaining screws, the back cannot be rotated by 90° to change the orientation of the lug.
