@kiriakost1969 Hi Kiriakost, I tried it, the readings I get before going to the low pass filter are around -318 & -317. I then go to the low pass filter in ACV mode and back to Min/Max/Peak (with low pass deactivated) and there is not much difference in the reading. What are you getting? How far negative is your reading compared to positive?
Great review Martin! I concur with your remark that 115 is very responsive, I also think that it has faster autoranging than 28II/87V models, maybe Fluke optimized hardware or firmware on 11x series. One thing puzlles me, I have not seen or heard lead alert when you switched to mA/A/uA range?
@mjlorton the lead alert is for when the lead is in either of the current input sockets, because they are both fused. So there is no lead alert when it is switched to any of the current ranges, because either the lead is correctly in either of the current sockets, or it is in the V etc socket, which is no problem.
Just a question, at minutes 34:00 through to about 35:45 you are demonstrating the micro-Amps with the solar panel. Through the whole part you had it still on AC volts. I don't know a great deal about solar panels... but was AC the correct microAmps setting for that test or should it have been DC? In what I do, I always work with DC current, and I'm constantly going to take a reading, then Grr!; have to go and switch it to DC and take the reading again. It gets to be a bit of a pain.
@samgab ...sorry, I mean it was set to AC microAmps the whole time of the solar panel test, rather than DC microAmps. Can't correct my previous post to better explain my question...
@mjlorton Ahh, but it's good you see: It perfectly demonstrates the frustration with it defaulting to AC. I do that all the time. Especially as I will often be switching between microAmps and MilliAmps... Every time I flick back and forth between the two, I have to remember to press the yellow button each time, or I get a garbled reading, then have to take the reading again!
@samgab Ok, annotation in place...but yes, very easy to make the mistake...and how clever of me to demonstate that ;-) !!! Do appreciate your feedback and eagle eye. Thank for the info on the TL175 leads as I was not 100% sure that Fluke were including them. Cheers,
Hi. Another excellent review, thanks for the time and effort that you put into it.
Thanks for referencing my comments too :)... Even after watching this review, I still think my initial feelings on this are the same, I'd still go with the 87V again. The 87V feels very robust, more than tough enough. I look forward to seeing if you end up with both side by side. Also, I agree with what you said about preferring it to default to DC Amps. Pity about that. New 87V came with the same TL175 leads.
Hello Martin I need from you to verify a software bug on the 28II.
Use the Min/Max/Peak and measure mains sine-wave 220 or what ever you have there.
You will get -315 & +315 (220V)
Then get out of this mode and activate the Low Pass filter ACV mode.
Then activate again the Min/Max/Peak and measure 220 Mains.
I bet that it will not measure -315 & +315 (220V) the measurement will show more negative volts than positive.

@mjlorton Hi Martin, I got a new precise measurement today.
Mains Volts 222 Min/Max/Peak -309/ +308 that looks normal.
With LPF on I got -317/+311
Your Fluke 28II looks to be the latest EUR version ( Latest Fluke naming ID),
My model was made at the beginning of 2011.
I am saying all those so to point out, that its possible to have discover an old bug of this model.
Even so I discover it five days ago, and I am seeking for the truth about it.

@Nermash Thanks for your comments. I will double check the alert feature and feedback. Cheers,

@samgab ...except if you have the lead in the A socket but the dial set to μA, in which case you get a lead alert in a current range.
samgab 2 months ago
@samgab Yes, makes perfect sense. Thanks for pointing that out.

@samgab Good eye, I did have it on mico amps...but AC instead of DC....I will add an annotation. Thanks.

Awesome review Martin. Afraid I'm a bit of an Agilent fan myself however I still love your thorough reviews on the Flukes etc.

@orbiter8 Thanks for you comments....I will try and get an Agilent as I've not had one in my hands yet...Thanks for watching.
