As we have discovered now, the new test means that 2000V will be applied to the amps jacks for one minute, with the fuses ruptured, to check for arcing between the terminals and the circuit.
The insulation on those wires looks identical on both meters and are probably the standard guage wiring that comes with that 9V battery clip, just like on the Fluke 87V, except that Fluke passed them through a spaghetti heat shield for safety.
Maybe they would pass the test with the current configuration.
In real life, a major problem may arise when a high voltage is measured with the probes in the wrong jacks. The fuses would do their job and rupture, but during the course of the meter's life, if the battery leads are frayed or the insulation damaged in any way, an unstoppable arc could develop, destroying the battery, with all the consequences we know about.
So my point is that, even if it passed the test, routing the battery leads in such a way on any meter, can only be described as careless.
