How you change the battery of your digital hardness tester or dial indicator.

The battery needs to be changed when the dial is flashing, dull or the battery sign appears. The battery is covered by a lid on top of the indicator on the left side.

• • 

  • Open the lid with a crew driver.

• • 

  • Take out the battery holder carefully.

• • 

  • Make sure you will remember the correct position.

    Hint: A photo from your smartphone will help you not forget the positioning of the battery holder and the battery.

• • 

  • On the battery you will find information about the type of battery used (e.g. SR44).

• • 

  • If possible, do not touch the new battery with your fingers. Use a piece of cloth.

• • 

  • When inserting the new battery be careful to not damage the contacts – the little metal parts inside.
