When using the ohmmeter function of the digital multimeter to check continuity, what does the "ol" in the display mean?

It usually stands for open loop, another way of saying there isn't continuity.

or  it can also means OVER-LIMIT

beyond the limits of the meter to register, such as "infinity" on a resistance scale

which are both the same thing

Explanation:

there is no universally accepted definition of art. although commonly used to describe something of beauty, or a skill which produces an aesthetic result, there is no clear line in principle between (say) a unique piece of handmade sculpture, and a mass-produced but visually attractive item. we might say that art requires thought - some kind of creative impulse - but this raises more questions: for example, how much thought is required? if someone flings paint at a canvas, hoping by this action to create a work of art, does the result automatically constitute art?
