My own comments:

  - large, robust, quite heavy instrument in a thick vinyl case

  - compare to its age, measures very accurately

  - I met two types:

    - only measures up to 1200V, it has a lower lid, the high-voltage measuring cables are not included

    - It measures up to 6000V, it has a thick lid that holds the high-voltage measuring cables under a cover.
