BATTERY REPLACEMENT
All components have been selected to mini-
mize current drain without compromising func-
tionality.
In order to minimize the battery consumption,
the meter is equipped with an auto-shut off
function which switches the meter off after 5
minutes of non-use.
The power source is 4 x 1.5V batteries with an
expected life of 60 hours, or over 900 measure-
ments.
To always grant accurate measurements, the
batteries are monitored to ensure that readings
are not taken when there is insufficient power .
A "LO BAT" indication will appear on the lower
right hand side of the display when the batteries
are weak and require replacement; at this point
the instrument is able to perform only 50 more
measurements.
A "-BA-" indication will appear on the display
when the batteries are too weak to perform
measurements; the message appears for a few
seconds, and then the meter will automatically
switch off; at this point it is absolutely neces-
sary to replace the batteries to use the instru-
ment.
