Maintenance

5.1 CHARGING THE BATTERY

The device can only be used on battery power. Therefore, the battery must be charged regularly. One battery charge is sufficient for approximately 2500 measurements or 19 hours of continuous use.

To charge the battery, place the MESI THERMO UNIT on the MESI LARGE CHARGING PLATE (CS4SYS) or MESI SMALL CHARGING PLATE (CS2SYS). During the charging process, the light on the module will flash orange. Only when the device is completely charged will it start flashing green. For more information, see chapter 4.7 – Multifunctional buttons.

If the capacity of the battery is significantly decreased after a period of intensive use, the battery is most likely spent and should be replaced. As the device does not contain any parts that can be replaced by a user, contact your local distributor or the manufacturer for battery replacement.
