| Fluke 233 cut off under 20mA |

Hi guys, I have a question about the Fluke 233. Data sheet says: AC Current Range 1mA to 10A Accuracy 1.5% + 3 DC Current Range 1mA to 10A Accuracy 1.0% + 3 Okay, so far so good. But my 233 cuts off everything under 20mA. See pictures. Can someone explain me why? If it has something to do with the accuracy, can someone calculate it for me? Would be really nice. Am currently stumped. Greets from Germany |

What happens if you manually change ranges to the lowest AC current range? |

BeBuLamar are right. 6A is the lowest current range. I have set up a test circuit with a potentiometer. So I can regulate the current. 0mA and then comes 20mA. No value in between. The pictures were taken right on the limit. |

According to page 41 of the manual (https://dam-assets.fluke.com/s3fs-public/233_____umeng0000.pdf), all AC current "ranges are specified from 5 % of range to 100 % of range." AC voltage is from 1% to 100%. |
