| Agilent Multimeter U1252B Blown up |
| (1/1) |

Two of my company's U1252B have burnt mark traces in their PCB. |O I don't recall doing anything weird. I was measuring the voltage and frequency of 1000Vrms signals. Peak-to-peak voltage is max 3000V (which is higher than the written 1000V max), shouldn't it give me a warning or something? I used the same rated CAT III 1000V Fluke 289 and 87V, and they are both perfectly fine. I even used the BM235, which is only rated for CATII 1000V, no problem! What should I do with them? Use them as paperweights? :-DD |

I'd say they're toast. This 3000Vp-p AC voltage, is it symmetrical or is there a DC component? IOW, what is Vpk or the absolute peak voltage at any time? I'm glad your other meters didn't blow up, but when I'm looking at high voltages like this where I don't actually know what the signal might look like, I prefer to use a HV divider probe like the Fluke 80K-6. |
