Why can't I change the display measurement unit on my SMC Networks PF3A801H-L?
If the display measurement unit on your SMC Networks Switch cannot be changed, it may be because the selected model does not have a unit conversion function. The unit selection function is not available for models fixed to SI units. If this is not the issue, consider replacing the product.
