1.11 (Release date: June 20, 2017)

Key improvements

•Fixed measurement functions for all oils & alcohol
•Added a feature to re-align the touch screen.

To re-align the touch screen, hold the power button and quickly tap screen 5 times, then release power button.  We recommend using a wooden chopstick or toothpick to touch the alignment dots as it would be more accurate than your finger.  Please do not use a sharp metal object as that may permanently damage the screen.
• Fixed issue that caused firmware to update to the same version


This version of firmware has a *much* more extensive way to factory calibrate the device.  The default values should work for most existing devices, however, if you are still experiencing measurement issues there are two courses of action:

(1)    In about a week, we should have calibration kits available – along with firmware that allows you to perform the same factory style re-calibration. This would be the best option from a time savings perspective.
(2)    Send it back to us for re-calibration. Go to support site and file a ticket: Request Support Ticket.  Typical turn-around time for this process is 1-2 weeks.

As always we appreciate your support and patience.

Thank you so much,

tCheck Support Team
