Maintenance
Cleaning and storage
1. The white plastic sensor dome should be cleaned with a damp cloth when necessary.
2. Store the meter in an area with moderate temperature and humidity (refer to the
operating and storage range in the specifications chart earlier in this manual).
Battery Replacement
When the battery power falls low, the ‘BT’ symbol will appear on the lower left-hand side of
the LCD. Replace the six (6) 1.5 ‘AAA’ batteries by removing the rear (center) battery
compartment screw and accessing the battery compartment. Observe polarity when
placing the batteries in the compartment. Ensure that the compartment cover is securely
fastened when finished.
