Mahr GmbH • Multimar 844 S

8.6  Setting in proper position provides maximum measuring accuracy

 

 The 

Multimar 844 S

 setting instrument can be equipped with the optional 

844 Sf

 base 

plate. This allows the 

Multimar 844 S

 to be used in a vertical position as well.

To achieve maximum measuring accuracy, a comparative measuring instrument should be set 

in the same position and measurement in or on the work piece should occur.

Example: 

A precise hole in a turned part should be measured in the lathe with a 844 N 

bore gage. To do this, the 844 N bore gage must be inserted horizontally. It is in exactly this 

horizontal position that the 844 N bore gage is to be previously calibrated.

Please note:

 When setting the 

Multimar 844 S 

setting instrument in the vertical position, it is 

recommended that the fixed measuring contact be placed on the lower parallel jaw.

 This way, the dead weight of the measuring instrument is supported by the lower parallel 

jaw and not by the movable, spring-mounted, probe.
