On a IM-270 any dose less than what will display a zero?

Explanation:
The IM-270 readout is in tens; it can display 10, 20, 30, and so on, but it can’t show single-digit values. So any dose below 10 units won’t register on the display and will appear as zero. That’s why the threshold is 10—doses under that level are effectively rounded down to zero on the readout. If you could have a smaller increment, like 5 or 1, you’d see readings above zero at those levels, but the IM-270’s display resolution doesn’t allow that.
