HABOTEST HT5910 wrong measurements

[@marcosnunes3052]

A diferença é causada pelo trigger que dependendo do momento na curva senoidal o valor tambem altera! Por isso tem que Fazer 3 testes e extrair as medias!

What brand circuit breaker is there ? I have seen with my own eye how Chint / Noark breaker is manipulating with tester giving different measurements ... Measured with FLUKE

[@chok-d67]

Does this brand of measuring instrument have a high error?

Entweder dein gerät ist kaputt oder deine Leitungen sind uhr alt, den selben gerät habe ich auch und funktioniert tiptop

[@joeramos7973]

all the grounds of the building are linked and that creates alterations in the measurement, perhaps it would be better to measure on the same copper rod from the well to the ground (it is just an idea). Have you seen the UNI-T Multifunction Tester instrument UT595?? will it be more reliable?. Saludos!!

[@bernhardneuner1282]

Hi, no - at the same socket the measurement must be the same. E.g. for 300mA and 500mA the results must be the same by ohmic law. This tester always shows 0 Ohm if you set 300mA test-current. See my other video than you know what I mean.... ;-)

[@joeramos7973]

@@bernhardneuner1282 uhm ok if I saw the video you mention, the equipment is not accurate, is there something that measures the equipment well, or all the functions are wrong

[@flolandshut]

Loop resistance is not really measured, its calculated! So it will differ even at the same socket. Belongs to voltage, loads nearby and so on!

This brand of measuring instrument Measure loop impedance Is it reliable? Why are the measured values not the same?

[@Menshinin]

Возможно, не должно быть других работающих потребителей в сети во время измерения.

Скажите,это ведь измерение петли фаза-ноль?Или я ошибаюсь?

[@Menshinin]

@@НиколайВикторович-ц4н теоретически да, но на практике эти приборы ничего интересного в этом аспекте не измеряют. Вот УЗО они тестируют очень хорошо.

you pay 150 euro and the result is the same, cheap china part ! i think about to buy one of this for myself too :) ... the price is too good not to try

[@bernhardneuner1282]

I paid 107 euro but this was to much! The results are unreliable! The 300mA Range shows always 0Ohm.... 500mA Shows 4.9Ohm... so what now?... (another measurements at one socket with 500mA RCD, see other video).

[@fabienchereault1883]

The result is certainly correct the loop resistance always varies a little bit especially on values ​​as close to 0

[@bernhardneuner1282]

Yes round about 0 Ohm would be nice - but I had measured on the same socket 0.0 Ohm and 4.8 Ohm - and this is not correct. The 300mA-Range of this device always show 0 Ohm.... I had to be below 1.9 Ohm - and with this tester there is no reliable results!

So ein fehler passiert auch mit Profis Messgeräte 😉

[@flolandshut]

Ganz normal das es keine Messung sondern ein errechneter Wert ist
