| Multimeter CAT II Rating Discontinuation |

| J-R:
Quick reminder, the CAT II labeling removal only applies to handheld DMMs, according to what I posted previously. I have not seen anything yet that states the rating itself is going away or changing otherwise. |

I've never understood how CAT I was applied anyway--you see CAT I/1000V on meters that are explicitly not rated for 1000VAC. |

Since the CAT ratings are safety ratings, it seems logical to me that you could have a device rated for CAT I 1000V but not actually be able to measure it. Although maybe that is not allowed, but without the full document I can't say for sure. |
