Maintenance and Testing
Your meter needs little or no maintenance with normal use. It automatically
tests its own systems every time you turn it on and lets you know if
something is wrong. (See "Screen Messages" and what to do about them.)
To make sure the display is working properly, turn off the meter. Press and
hold ON/OFF button to see the complete display. All the indicators should
be clear and look exactly like the picture to the left. If not, please call the
Customer Care Service toll-free at 866-994-3345 (Eastern Time, Mon-Fri
9:00AM~5:00PM). During non-service hours, please contact your local
dealer.
