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 battery 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.
