Yes, we can, though it would help if we knew what we are talking about.

Common instrumentation acronymns are:

LRV means Lower Range Value

URV means Upper Range Value

LRL means Lower Range Limit

URL mean Upper Range Limit

---------

What does LSL mean?

What does USL mean?

LSL LOW SCALE LIMIT OR LRL LOW RANGE LIMIT

USL LOW SCALE LIMITE OR URL LOW RANGE LIMIT

BOTH MEANING IS SAME

In my experience, "LSL" means "Lower Sensor Limit" and "USL" means "Upper Sensor Limit". If the sensor cannot register negative values, then you cannot set either range value to a negative number.

Well, a LRV (value) of -1 is less than zero. -1 < 0

If the lower limit is zero, how can a value less than zero be accomodated?

Check out your associate's (alter ego?) identical question, with far more information on the situation in this thread on Control.com
