Hi richard
You hit the nail on the head. All test equipment currently on the market (with exeption of the PrimeTest 300) have problems when testing at currents less than 1A. As per our research you need at least 5-6Amps to overcome common issues (wetting contacts).

The IEC 62353 clearly states 'use a current of at least 200mA at 500mOhms - max. voltage of 24V'. this does not exclude any current used at present. IEC 62353 also states that IEC 60601-1 tests can be carried out if the safety of the test engineer can be guaranteed. We can go into a big debate about IEC 62353 and future encertainties but this is most certainly not the intend of the initial post.

Do not fear the future. People already do what they feel necessary based on experience and risk assessment. Nothing much will change in the future. Just a little more help and consistency across Europe.

Feel free to contact me should you like to discuss IEC 62353.
