Piece Counting Indicator

In piece counting, a "three window indicator" likely refers to a method or device used to count pieces efficiently or accurately, but without more context, it's difficult to provide a precise explanation. However, I can offer some general interpretations:

1. Manual Counting Device: A "three window indicator" could be a handheld device with three small windows through which you count pieces. Each window might represent a certain quantity of pieces, and as you count them, you move to the next window until you've counted all the pieces.

2. Digital Counter: It might also refer to a digital counter with three distinct digits, each representing a count of pieces. This could be a handheld device or even a feature in a piece-counting machine.

3. Visual Aid: Another interpretation could be a visual aid or guide used in counting pieces. This could involve dividing the counting area into three sections, each with its own indicator to help track the count as pieces are sorted or tallied.

Without more specific context, it's hard to pinpoint the exact meaning. However, these interpretations might give you a general idea of what a "three window indicator" could entail in piece counting.
