Just so other's that might want one know in advance. They take non-standard lead/probes the end that goes into the unit is bayonet style so you can not just get a set at RatShack. Plus being rated up to 5000VDC/5000VAC you really have to make sure you are useing leads that can support that type of voltage. Second it takes an expensive 30V Everyready 413 Battery that runs from $10-$27 depending on where you shop and how many you buy at one time. SO again not something you can run to RatShack or Wally World and pick up at 2 in the morning! My unit while new is missing it's leads and it's battery. It comes in a nice leather carry case. I was at the web site checking out leads which are reasonable and the Leather case alone for the 630 line runs $65 so I am not too hurt about it missing the $17 leads and given it's odd ball 30V battery it is no wounder it does not come with one. If it did someone long ago took it out while it sat on the shelf for their in factory use.I am sure that is what happened to the leads too. The guy I bought it from buys up company's in liquidation and their industrial parts and supplies. So just know in advance that while the leads are cheap the ZInk Carbon specialty battery it takes is not cheap or readily available so be prepared for that. The case appears to be bakealite in the photo so this bad boy must be from no newer then the 1980's I would imagine. Plenty of them on Ebay. Just make sure you follow what CaptinKillowatt said about looking in the lower left hand corner for two extra ports labled 5000VDC and 5000VAC so you know you are getting one that goes up to that voltage because not all of them do some stop at 1000V. I am not too worried as long as I can get batterys but I am sure it would not be hard to use 3x 9Volts or if need be 4 and a resistor to get it to 30V and limit current draw. If they ever totally stopped making them. I just wanted to make sure everyone know this since I just found out looking on line for any reading material on them like an online owner's manual or the like. I am so excited I am off to order some battery's and a set of leads.
