Hi Russell
Can the HS36 read millivolts as in a pilot light thermocouple?
Thanks

What is the millivolt output of the thermocouple you are testing? The HS36 accuracy for 200m is 1.2% + 5/0.1m.

I just set mine to AUTO VDC, it will auto-range what ever DC voltage your looking to read.
I have no problem measuring the 17mVDC or so from a thermocouple to reading the higher mVDC from a thermopile.
Love my HS36...here is a reveiw I did some time back.

Nice review slc. I was thinking about something new. You didn't mention anything about moisture. My UEi DL379Pro goes crazy around the occasional spritz but I am still not ready for a full waterproof meter and they always seem to be missing something 
Also I see you have the adapter head with leads but have you ever just connected the leads with the tips removed to attach an accessory head? Any drawbacks to doing this? I'm cheap

No issue with moisture...funny you should bring this up. Was on a service call this summer and was troubleshooting a rooftop. A freak rain storm blasted through and I loaded up everything, but accidentally left the meter hanging there. Came back an hour later and was very happy to see that nothing happened to it. Now not saying everyones experiences are the same. I have gone in and out of -20 ice cream freezers and did not have any issues with condensation hurting the meter...yet.
You can just plug the meter leads right into the base of any head. That works fine. Bit of a tight spot trying to get your fingers to wedge the ends onto the terminals. Figured for 15 bucks for the adaptor, can just beat the crap out of those leads.

Hi Sic
just asked because I got a weird reading on a no pilot call. But yes you're correct it reads very well in Auto range or at the lowest setting.
Hey itsiceman
I just recently purchased a UEI DL389 and after a short time I found out
the UEI will not display micro amps below 1.0.
I consulted with their tech dept. and the Canadian division was quite surprised when they checked it out and found this to be the case but could not give a reason why this is so. The tech support in the U.S after consulting with their engineers told me its just the design of their chip and they felt that a reading below 1.0 was a poor micro amp range so they just designed it this way.
To me that is not good enough. There is some spark boards such as Johnson controls where the acceptable range is like .75 micro-amps.
Check it out next time you are on a flame sensor call. If the current is below 1.0 microamps it will not display .9, .8, .7 etc It will only display 0.
Needless to say I felt this is flaw in their design, so the UEI DL389 went back to my wholesaler and I got my refund and promptly went and purchased the Fieldpiece HS36. Awesome meter and I am very happy with it. Only negative was that the DL389 had the inrush capability @ 20mseconds
Where the HS36 does not have inrush reading capability.

Also big kudos to you
Thats a great review you posted. Very well written and great pics.
Big Thanks
I hope more reviews such as yours will be posted on products in the future.
Kinda wish there would have been a honest review posted on the UEI DL389
then I may have not have had to find the flaw after the purchase.
Thanks again

The UEi is fast with voltage drops too. Sorry don't have a M# but I had compared with a building Eng's Fluke and it would read lower voltge when a compressor was starting and tripping a control board safety. All I remember was it being a clamp meter.
