The Yellow Jacket probes pair the same way as the other brands we support - see How to Pair Bluetooth Tools - with the exception of the amp clamps. When viewing the amp clamps in the Toolbox screen they will always say "Tap to Map"; they cannot be assigned there. The amp clamps get assigned on the electrical measurements page as shown below. Unlike the other multimeters where you capture the measurements in the Power tab, you need to switch to Phase to Phase measurements as outlined in red then click "Activate".

If you're using multiple Y-Jack amp clamps, a pop up window will appear where you will need to chose which amp clamp you would like to reference for the measurement. Then click the green "Capture" button (not pictured).
