I am routinely dealing with electric motors or other electrical installations that have some earth leakage and trip the RCD. In such cases, an insulation resistance tester is an invaluable tool.
I have a UNI T UT513, but it is quite a beast to haul around. So it would be nice to have a multimeter with an integrated insulation resistance tester.
But all such meters are made by Fluke, Gossen Metrawatt, Keysight, etc. Is there any cheaper meter available?
I am not interested in particularly high voltages, or measuring Polarization Index and such. A single resistance measurement as a pass/fail test is enough for my needs.
