Used to verify proper installation of Schlueter tile floor heating cable

Bought to check the installation of a heated bathroom floor. Schluter warranty coverage is dependent on pre- and post-installation testing using a megger. And a standard digital multimeter is incapable of measuring gigaohms and will not provide the required 1000V (Schlueter requirement). This device makes a well-made impression. The meter comes with a stepped, detachable, impact-resistant case to protect the meter. Test leads, batteries, instructions and a carrying case were also included…

Pros
  • . Capacitance and Resistance Meter
Cons
  • Ugly Packaging

Device works, no instructions

Not calibrated or thoroughly tested but works for my use. No wonder this doesn't work for some people considering it costs 1/10 (or less) the cost of good quality. I really think some people writing reviews say it didn't work, just maybe misused (e.g. reading - the resistor only shows "1" - it's the same as what it shows, if it's not connected to the circuit at all, you'll have to check it (very carefully, or not at all a badly insulated circuit, or (more carefully) directly to the chain.) But…

Works perfectly out of the box, accuracy well tested.

I bought a BTMETER BT-6688B tester to evaluate and compare the bottom shoe insulation. Its ranges of 200 gig and 5 kV are very critical for me. Other measuring devices are not so expensive or the costs are too high for me. I also like this model because it has an actual resistance value and not just an LED display showing, for example, "resistance between 10 and 100 MΩ" - that's not enough for me. I also like the simplicity of the meter, nothing pretentious, no preparation. It has two side…

Pros
  • Check, measure and inspect
Cons
  • I will add later
