Hello,
Unfortunately not, like add frequencies and temperatures measurement. :(

Hi everyone ,
I modified follow page 20, and detect a problems with value of switch Range up : example 10000 counts , they set address 12,13 =27D8H =10200 mean when DMM counter over 10200 will be switch range , but if voltage measure is 10v so it will show OL on screen , really not good :-\ . Solution is set switch range up= 9800 and switch range down =960 so we will cover full range , voltage display auto switch range when over 9800 count , ex: 9.700v ->9.799v -> 09.80v -> 10.00v ->50.00v , down 10.00 ->09.80 ->09.70v ->9.600v ->9.500v . should be better
brainwash:
I've modified my unit with the Arduino skecth JAY_i2cArduino210E.ino from @jayjr1105 .
The calibration values on my 1106 were completely different than anywhere else.
I've calibrated the DC clamp as outlined in the video by "joe smith" using the two in-line trimmers on the back. Now I'm consistently <20mA at zero, allowing me to avoid the dotless mode.
So the 2A modes for me are: dot DC, dot AC, dotless DC, dotless AC. Until ~2A I can use the dot mode and zero the meter, above 2A I can use the dot mode without zeroing, since 20mA of error is not a big deal.
The only downside to using this as my main portable meter is the slow continuity mode.
mgruber:
I just got myself a UT210E to check the standby current at the battery terminals of my car in 2A mode thru the clamp, which worked fine.
Then out of curiosity I switched the mode dial to 100A to check the current when the car is running (my car has a 90A generator).
I then was distracted by a neighbor and forgot to remove the meter before starting up the car (which typically creates about 400A for a second or so).
Now my meter reads about 0.200A (slowly decreasing) in 2A mode as opposed to the 0.000-0.0002 I had out of the box.
Did this 400A spike manage to permanently damage s.th. in the meter or will this return to zero after a while?
Hydron:
You probably just need to degauss the clamp.
Ideally this is done with a steadily decreasing AC current in a big coil, but you might be able to do it with a permanent magnet attached to a drill or something (move it away slowly to decrease the oscillating field to zero). I've even corrected small offsets by hand with careful magnet waving but it's not the ideal method!
