Still using an analog meter? ;-) Mine lasted many years, and a few falls from towers onto concrete floors until it finally gave up the ghost. During that time I had two digital multimeters die all by themselves, and they were treated very carefully (they cost a lot!). Just a note about those button batteries: If you handle them, your finger grease can provide enough of a current path to prematurely flatten the cell. Try to avoid putting your fingers across the terminals, and wipe them clean if you do (the terminals, not your fingers - well wipe them clean too before you eat). ;-) -- Don't send private replies to my address, the mailbox is ignored.
