When A dial is zeroed at the 3 o'clock position, a positive reading when measuring horizontal moves would require moving the machine to the __________ when looking at the equipment from the fixed machine to the MTBS.

When a dial is zeroed at the 3 o'clock position, it means that the baseline reference is established to measure any horizontal movements from that point. A positive reading on the dial suggests the machine has moved in a direction that would increase the reading from the zero point.

In this context, if you are viewing the equipment from the fixed machine to the moving target bearing surface (MTBS), a positive reading is associated with a movement to the right. This aligns with the way the dial gauge indicates changes; as the pointer moves clockwise past the zero position (3 o'clock), it reflects a positive measurement. Therefore, to achieve a positive reading, the machine must be moved to the right, altering its position in a way that the dial indicates an increase.

Understanding the concept of how measurements are taken establishes the basis for recognizing the implications of dial positioning when aligning machinery.
