Is there a way to slow how fast the display changes per second? In colder weather the LCD just can't keep up with any quick changes making any reading very difficult to read. Only thing I came up with was to change the range and seems to help. I have a different meter with a internal temp sensor that will automatically slow the display in cold weather for this same reason just wasn't sure if there is a feature like this that can be set on the 87V when needed :-//

For sure its not a solution, but perhaps this will improve a bit, by enabling the smoothing feature maybe ?
By holding the "Range" button when powering it on, display will show "S---" means smoothing feature is on.

It would seem odd that the meter would slow the rate at which it tries to update the display just because it's cold. However, the cold LCD will respond slowly so I could believe that the bar graph would be useless.

How cold is cold? Manual says operating temperature -20C to +55C. While I can easily test -20C, I have no incentive to!
What is the measurement that you are trying to read? Does the reading fluctuate a lot or is it a wide range?
-
Yes the smoothing feature will probably take care of it. Thanks.
This is a new meter for me so only noticed it twice so far and it isn't too cold here yet (20ºF)
I'll take some video to help explain.
I am taking readings indoors and out sometimes in walk in freezers but typically in and out of those short term.
The meter does stay in my service vehicle so when it is cold out my meter is cold and from there I go on a roof or inside.
The last time it was an issue was on a ice machine water level sensor that sends between 4.5-5 VDC to a control board depending on the water level position. Another time was just checking simple yes no type of readings between different points in a 115VAC control box. Thanks for the help guys.

Hmmm, one example where the old analog VOM has an advantage.
-
That's ironic. It's been about 20 years since I laid my old roll top Simpson to rest.
I think I made the switch to digital back then because they were easier to read lol :o
;D

Agilent OLED meter might be a better option in extreme low temps. If the chuffing batteries lasted more than 10 minutes.
