Review: -) - Solid bit of kit for the price
Review: Tough pro tool - I’ve had a fluke and I would say I prefer the Kline to the fluke. This Kline et600 has everything you really need, except amperage. The continuity buzzer is good in my opinion, I work in houses mainly and it’s plenty loud for me but if you are in louder environments you may find it hard to hear. The resistance, voltage, and insulation tests are all easy to read and accurate, I’ve checked many heaters, motors and valves and the klines always given the reading I would expect. The meter itself is very tough and I would say atleast as well built as the fluke I had. It feels like a quality tool- and I would definitely choose Kline tools based on this machine for future purchases.

## Questions & Answers

**Q: Does this have a calibration certificate? Maybe isn't good enough, i need to know for sure.**
A: No, it doesn't come with one. The unit is too cheap for a calibration certificate to be effective.

**Q: Does this come calibrated?**
A: As it’s new I’d say it should be. I have my own test box and when testing the readings are spot on.
