ALTO - Update to the latest firmware directly from Google Chrome or Microsoft Edge browsers
How to Connect Your ALTO To Your Computer
Connect a USB-C cable into your computer’s USB port. The included USB-C cable is ideal. If not using the included cable, make sure the cable is not a power-only cable and has data lines, most cords included for devices that only need charging (flashlights, earbuds, etc.) don’t include data lines. Cell phones, USB hubs, any cable that came with device needing more than just power will have them.
Turn off the ALTO if it is on
Hold down the right button
With your other hand, insert the USB-C cable into the meter’s USB port.
When prompted on the ALTO screen, release the right button and hold the left button
Keep holding the left button until a couple seconds after the screen goes blank. A storage device should appear on your computer.
