Is it normal that I get 312pF when nothing is connected?? I found these UT-61E at a school lab |
| Hydrawerk:
I got much better results on some old multimeters. UT70A from 2009, DT-890G from early 2000s and the M-3650D is more old, probably from mid 1990s. (I do not know if this was discussed earlier in this thread...) |

The capacitance is a bit on the high side. Mine shows 84 pF with the leads connected, about 58 pF without any leads. The manual specifies 50pF as normal/acceptable, and that you should use the REL button to zero it out. Still, i wouldn't worry very much about it, though i would test the capacitance function with several known capacitors. |

Thank you for the advice. My thoughts on the meter: The two buttons (blue and yellow) are confusing. Why no LCD backlight? Strange on a 22000 counts DMM. The autoranging is quite fast. Beeper is fast. I like the OFF position of the rotary switch. Now the DMM cannot turn on when carried in a backpack. Well, i prefer Brymen (not owning one yet) but this UT61E is probably an OK multimeter for most needs, especially if you do not work with high energy circuits. |
