The display may only be cleaned with an appropriate glass cleaner. Rub the display
with a dry, clean and lint-free cloth. Do not allow cleaning fluid to enter the instrument.
Internal battery replacement
An internal CR2032 coin cell battery powers the real-time clock circuit which provides
continuous time stamp for the instrument. If the battery fails, the system clock and time
stamp for the logging function are not available but other instrument functions are not
affected.
Under normal usage at room temperature, the battery is expected to last up to 10
years. However, the battery life expectancy is reduced if the device is stored at temper-
ature above 40°C for an extended period of time.
If the instrument cannot retain the date and time settings after turning off the AC input,
the battery is discharged.
Contact your local service partner for battery replacement.
