Purchased an older, used Ohaus 10-10 beam scale but it didn't come with an instruction manual. Went to the Ohaus site and contacted their customer/tech support to see if I could obtain one on these discontinued scales. Got a reply back within 24 hours and two separate manuals attached to the email. Now that's customer service for you. Shame it is all too rare these days. Hats off to Ohaus!
