step 3 Engine Machining for 4g63

Having a hard time with understanding the dial bore gauge. one minute the measurement is on either sides of the zero but it seems to be counted as the same Clearence. for example the big end conrod showed 0.002 of an inches of clearance but it was to the left of the gauge. what would be the reading if it was that same number but to the right of the gauge. i may need to revisit the gauge reading section because I don't remember seeing the difference.
