Maintenance
Regular maintenance improves the life span of the instrument, the following chap-
ter provides information on instrument maintenance.
Cleaning
Before cleaning the instrument, ensure that it has been switched off and the
power cable is disconnected.
Clean the outer case of the instrument at regular intervals, using a soft, lint-free
dust cloth.
Instrument damage caused by cleaning agents
Use a dry, lint-free cloth to clean the product. When cleaning, keep in mind
that the casing is not waterproof. Do not use any liquids for cleaning.
Cleaning agents, solvents (thinners, acetone), acids and bases can dam-
age the front panel labeling, plastic parts and display.
The display may only be cleaned with an appropriate glass cleaner. Rub the dis-
play 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 pro-
vides 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 instru-
ment 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
temperature 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.
