Reviews
TIS 851 Voltage & Continuity Tester - Self Proving is rated 4.5 out of 5 by 11.
Rated 5 out of 5 by from Worth the money Great piece of kit a big plus not needing a seperate proving device

Rated 5 out of 5 by from Great Value Bought this week so haven't been able to reply put it to the test. I does however have all the features that I need, particularly the self proving facility. Beware however. The manual has a few misprints. There is an error relating to which LEDs light up during the self proving process. I have emailed TIS and they admit that there is a misprint and they are in the process of amending this.

Rated 4 out of 5 by from A must have for the professional or DiY'er Purchased this as all I have in my toolbox is a volt stick, the TIS 851 has the ability to give an exact reading of voltage levels, it also has the continuity test which is a must when fault finding. The only downside is that the prongs puncture the case when stowed away, without removing them there is no way to prevent this. This review would have been 5 star had this issue not been present.

Rated 5 out of 5 by from Basic, but effective Ideal multi-purpose tester, compact with lots of good features. Like the built-in proving system, saves carrying another piece of equipment when travelling.

Rated 1 out of 5 by from Broken. Don't buy Bought this, tested it when i got home, read 230v no problem. Used it at work a couple weeks later, reads 440v through a house with a 230 supply, then read the same again at another site, tested against 3 other testers. only glad it reads too high rather than a false negative. Regardless for the money it's not worth it, going with another brand for my next one.
