It is 400 mA HRC fused. An input warning alert functions for this jack But I am missing the 5mA range in that list. |

It is written on page 32 (File Version 04.12.2018) "This input jack is used for the 50 mA, 500 µA and 50 μA current ranges This input jack is used for the 10 A, 5 A and 500 mA current ranges. " But yeah, a bit hidden... --- Quote from: Terry01 on December 09, 2018, 03:47:39 pm --- --- Quote from: Terry01 on December 08, 2018, 01:51:18 am --- --- Quote from: bicycleguy on December 08, 2018, 01:42:29 am --- --- Quote from: Terry01 on December 07, 2018, 04:42:20 pm ---... I also see no one else has told me that and I have made a couple of posts about trying to feed 90mA into the mA jack so it can't be that obvious or well know or someone else would have said. --- End quote --- Thought you'd figure it out. Didn't want to make you feel like an idiot :D Don't feel bad though, Iv'e done the same thing a few times but usually RTFM. |O --- End quote --- LOL... Nice one! :) I still haven't read the manual but someone posted saying they searched the newest revision of the manual and it doesn't mention it anywhere. I haven't checked so I don't know if it says so or not, but i'll stick with the guy who says "it doesn't mention it anywhere", makes me feel a little less stupid! Ha Ha! :-+ --- End quote --- So I went and read the latest updated manual for the 121GW today, dated 4th Dec 2018. https://www.eevblog.com/wp-content/plugins/download-attachments/includes/download.php?id=19232 It doesn't say no where about the 55mA limit on the mA jack! It does however clearly say you should stick to alkaline and give lithium a miss. I found it to be a good well set out manual and as someone who isn't so well experienced with these things as others here on the forum, I found it very easy to understand and get to grips with. This meter really does have all the bells and whistles if you take the time to learn how to use it "properly" and understand all the features. I did think "the meter" had a couple problems at first so that kind of put me off it. Turns out RTFM is very important indeed for this meter! I stand corrected and the lithium mistake was mine but i still think the 55mA thing should be pointed out more obvious somewhere in the manual or even on the meter it's self as it is a rather neat niche function. I will make the changes needed as set out in the manual and give it another chance as it seems one of the main the things I thought were wrong with the meter were actually my being naïve or mistake and not the meter. I'll report back soon now I know how to operate it properly! I have a feeling I will be referring back to the manual a few times! :) --- End quote --- |

It's unusual to have 500mA in the amps jack ( because of low burden ) , but on older multimeters is written " A 500mA " so you can see even if you didn't read the manual or you forgot . I think they removed this on newer models , just " A " ... as in the picture from the manual . |

--- Quote from: Terry01 on December 09, 2018, 04:34:16 pm ---Now it is pointed out though I see it is a 50mA limit and not a "55mA limit" as someone else stated to start this whole thing. --- End quote --- The actual limit is 55mA, but in many multimeter specifications values are rounded down. |

A question about logging: Is it possible to log both frequency and voltage simultaneously in ac mode and automatic logging? |
