T+Pro vs T+Pro CAN

 

The Canada (CAN) version doesn’t have the 277V voltage indicator. Instead it either has an “AC” button (as indicated below) or a 347V button.

The reason is because typical 3-phase systems in Canada are 600V whereas in the US they’re 480V. On a 600V 3-phase system, the voltage from any leg to ground is 347V. On a 480 3-phase system, the voltage from any leg to ground is 277V.
