Although it bought for about half a year, it suddenly displayed an abnormal numerical value (ordinary orders of magnitude) without warning, and it began to wander. Also, since the cross section is round, it rolls.

The feeling of use of the power switch is bad. I am satisfied with the performance.

I had PH - 6011A, but due to breakdown, there is stock, I purchased the next day shipping. 6011 A has 2 digits after the decimal point, here 1 digit. Although there is no functional problem, it takes time until the value calms down. If it is 2 digits after the decimal point, you can see that the value is moving and you can wait until it stabilizes, but it is difficult to understand whether it is stable if it is one digit.
