2.1 Installing the Batteries
Install the batteries first.
CAUTION
Select a relatively moisture-free location when installing batteries in the meter.
When installing batteries, observe correct polarity (battery orientation). Failure to do so
may damage to the meter.
Remove batteries from the meter if it is to be stored for an extended period of time.
Do not leave dead batteries in the meter. They may leak and cause meter failure or
erratic operation of the meter.
When replacing batteries, replace both batteries at the same time. If only one battery is
replaced, the new battery may discharge into the old battery, which may leak chemicals
and damage the meter.
If the battery box gasket is damaged or dirty then the unit may no longer be waterproof;
replace the gasket in this case.
